Parameter dan Data IC Eprom TV Sharp Qbeat
Kerusakkan Yang Menyebabkan Siaran Bergeser
Lagi asyik-asyiknya nonton tv tiba-tiba siaran bergeser ,kadang cuma geser sedikit kadang juga banyak hingga membuat gambar tidak enak di tonton tentu menjengkelkan.
Komponen apa saja yang bisa menyebabkan siaran geser di antaranya:
Masih banyak lagi penyebab bergesernya siaran televisi yang belum bisa di utarakan disini mungkin ada rekan-rekan yang mau berbagi pengalamannya disini.Mohon maaf jika ada kekeliruan dalam menulis karena keterbatasan ilmu saya.
Terimakasih.
Komponen apa saja yang bisa menyebabkan siaran geser di antaranya:
- Tuner. Bagian ini merupakan komponen yang pertamakali menerima sinyal Radio dari pemancar Televisi.Disini sinyal RF diubah menjadi sinyal menengah (IF).Jika komponen tuner ini rusak ada beberapa gejala yang pernah saya temui diantaranya Siaran tidak ada samasekali,sinyal penerimaan lemah padahal antena sudah tinggi,siaran geser hingga membuat gambar tidak nampak (seperti gelombang air) kadang suaranya yang noise,salah satu atau dua band tidak berfungsi (UHF,VHF,VHFL tidak berfungsi).
-Dioda Zener 33 volt.Tegangan 33 volt sangat vital untuk mengunci frekuensi siaran (channel)maka sangat dibutuhkan tegangan yang sangat stabil,jika tegangan kurang stabil maka siaran akan bergeser.Dalam beberapa kasus dioda zener 33 volt ini sering rusak terutama jika panas berlebih (biasanya untuk kasus ini siaran akan bergeser setelah tv menyala beberapa saat,kadang dalam hitungan menit kadang hitungan jam).
-Resistor .Resistor ini untuk menghambat laju tegangan 33 volt yang akan masuk ke VT tuner biasanya Resistor ini berubah nilainya (15K).Dalam kasus yang saya temui resistor yang mensuplai tegangan 33 volt ini jika panas berubah nilainya.
-Kapasitor.Untuk memperhalus tegangan yang menuju VT (filter tegangan) dalam beberapa kasus kapasitor ini kondisinya kering sehingga jika kondisi panas siaran akan bergeser.
-Transistor.Sering saya menemui komponen ini jenuh,jadi jika di ukur memakai multitester normal tapi jika di pasang tidak berfungsi dengan baik.
-Trafo iF.Dalam beberapa kasus rusaknya trafo ini akan mengakibatkan siaran bergeser,bisa karena diputar putar sembarangan sehingga membuat berubahnya frekuensi IF.
Masih banyak lagi penyebab bergesernya siaran televisi yang belum bisa di utarakan disini mungkin ada rekan-rekan yang mau berbagi pengalamannya disini.Mohon maaf jika ada kekeliruan dalam menulis karena keterbatasan ilmu saya.
Terimakasih.
Cara mengatasi Tv Sharp Minta Password tanpa Remote
Mungkin rekan-rekan semua pernah mengalami kasus seperti saya Tv Sharp minta password seperti gambar diatas,sebenarnya kasusnya sangat simpel kalau ada remotenya.
Biasanya Password bisa direset dengan memasukkan angka "0000" atau"2398" maka password akan terbuka.
Tapi lain ceritanya jikalau tvnya tidak ada remotenya dan berada di daerah pelosok.
Rekan-rekan bisa membuka password tanpa remote dengan cara masuk ke servis mode tv sharp,biasanya menghubungkan dua buah jumper di main board (PCB) maka tv akan menyala normal,selanjutkan tinggal menonaktifkan Password tv di menu utama.
Semoga bermanfaat.
LCD Polytron 123 Mati Total
 Dapat servisan Polytron LCD 123 dengan type PLM 32B21 dengan gejala kerusakkan lampu standby mau menyala merah begitu power tv di hidupkan lampu standby mati tapi tv juga nggak mau hidup. Blok power supply  Setelah tv di buka terlihat ada beberapa komponen tv yang terbakar (FET,resistor,dioda) .Setelah baca-baca di internet baru tahu kalau yang terbakar blok inverter. Blok modul  Daripada pusing mau ganti satu set atau di perbaiki iseng jalur yang terbakar aku tetiti ternyata bukan regulator utama ,iseng jumper J529 ku lepas dari PCB lalu tv kuhidupkan ternyata mau menyala normal.Komponen yang terbakar seperti FET dan IC511 mending di lepas saja.  Semoga pengalamanku ada manfaatnya buat rekan-rekan semua.  |
Tips Mengatasi Kop Flyback Bocor
Berikut ini saya akan membagikan pengalaman saya guna mengatasi bocornya tegangan tinggi Flyback.Kasus yang di sertai bunyi mendesis dan kadang bau dari gas ozon yang sangat menyengat tentu sangat mengganggu kenyamanan saat menikmati siaran TV.
Berikut langkah-langkah mengatasi Kop FBT yang bocor
1. Bersihkan permukaan CRT di tempat Kop Flyback berada dengan kuas atau kain dan jangan lupa buang dulu muatan listrik di dalam Kop.
2. Jika dengan langkah di atas belum sembuh ganti kop flyback dengan yang masih bagus,untuk menegetahui kop yang masih bagus bisa di lihat dari bentuk fisiknya yang bagus adalah yang masih lentur dan bentuknya mulus serta jika di tempel di lantai keramik ataupun kaca masih mau lengket kuat.Kalau beli baru susah di dapat pakai saja bekas FBT yang telah rusak tapi kop masih bagus.
3. Jika dengan langkah di atas masih belum sembuh juga lapis permukaan kaca CRT tempat kop FBT berada dengan cat,saya biasa menggunakan cat meni besi mungkin bisa di coba dengan cat yang lain dan biarkan hingga kering.
4. Bila dengan langkah terakhir tegangan tinggi FBT masih bocor melalui kaca di luar kop FBT berarti tabung CRT bermasalah ganti aja dengan yang lain .
Demikian sedikit pengalaman saya mungkin dari rekan-rekan ada yang mempunyai solusi yang lain silahkan di tambahkan ...terimakasih..

Service Electric closing Mahanoy City office today

The building housing the Service Electric Cablevision business office
will close its doors today, with the seven employees being transferred
to the company's call center in the Humboldt Industrial Park, Hazle
Township.
MAHANOY CITY - Service Electric Cablevision Inc. will close its
business office in Mahanoy City today, with customers having until 5
p.m. to pay their bills locally.
The closing of the office in the town where cable television was founded is a matter of economics and efficiency, according to Service Electric Division Manager Timothy M. Trently.
"As you know, two years ago we purchased the Service Electric company (in Mahanoy City) and converted it over to Service Electric Cablevision," Trently said in a phone interview on Wednesday. "We're still part of the Service Electric family, part of the John Walsonavage family."
Trently said the building has more space than is needed to run the operation.
"This was certainly not an easy decision. The reason we are closing the Mahanoy City office is that there are only seven employees working out of that building, that building is very large and we're only using 30 percent of it to run the operation and 70 percent is going to waste. We're paying high electric, heating and air conditioning bills in a building that's not being utilized the way it should be. It's just not cost-effective."
Cable television began in Mahanoy City in 1948 when John and Margaret Walson Walsonavage erected an antenna on a nearby mountain to receive television signals from Philadelphia and bring those signals to their store that sold television sets. The mountains blocked those TV signals. Eventually, homes along the cable were also connected, creating the first cable television system. Walsonavage was recognized by the U.S. Congress and the National Cable Television Association as the founder of the cable television industry, according to the Service Electric website.
"We built our state-of-the-art building near Hazleton 12 years ago. Everything is under one roof," Trently said.
"Our warehouse is here. Our call center is here. All of our electronic gear is here and our satellite dish farm is here. Everything is at this one location, so it made sense to move those seven employees up here than relocate 60 employees down there and spend multi-million dollars there renovating that building for what we already have at Hazleton."
When asked about reaction from Mahanoy City residents about the closing, Trently said, "We've had some reaction. Yes, there has been disappointment expressed that we're closing the doors there, but also well-wishes for the employees and thanking us for all the time we served there. No employees are losing their jobs. We welcome them all to Hazleton."
In order to accommodate customers who came to the office to pay their bills, payment drop boxes have been installed at the Mahanoy City Food Store, 28 S. Main St., and at Klingaman's Office Supply, 124 E. Broad St., Tamaqua. Arrangements have been made to place payment boxes in the near future at McDonald's Lunch, 221 N. Second St., Girardville, and PRO Hardware, 220 S. Lehigh Ave., Frackville. Trently said a payment box site in Saint Clair is being sought.
Trently said payments by check can also be mailed to 380 Maplewood Drive, Humboldt Industrial Park, Hazle Township, PA 18202, or anyone paying by credit card can call the office at 800-242-3707. Payments can also be automatically be made each month from a checking account or credit card, or individually at the company website at www.secv.com. Call the toll-free number for more information on any payment option.
Trently said the company continues to upgrade the system that was part of the Mahanoy City-based Service Electric company.
"We've just recently completed our addition of the 115 high-definition channels there with the same basic channel line-up as we have with our Hazleton system," Trently said. "There are many more channels added to the digital tier and we'll be doing the fiber optics upgrades as soon as our hub gets built in Delano. We'll be increasing the fiber quantities so we'll be able to offer faster Internet speeds, better quality telephone service and, of course, television programming as it becomes available to us."
As for the building, Trently said options are being considered, including the possibilities of selling or leasing.
"We're certainly look at all avenues to see what the best use of the building could be," Trently said.
During Tuesday's Mahanoy City Borough Council meeting, President Patti Schnitzius read a letter from Trently informing the council of the closing. The letter was sent to all municipalities that are served through the Mahanoy City office.
The letter states the business office in Mahanoy City will be closed and operations will be transferred to offices in Hazle Township in the Humboldt Industrial Park.
"I spoke with Mr. Trently and said that I find it very sad that they will no longer be in the community," Schnitzius said. "It all started here. Mr. Trently assures me that Service Electric will continue to be a vital part of the community and help out financially, such as the Memorial Day program, the sesquicentennial and things of that nature."
Trently said that Service Electric will be active in communities as it as been.
"We will not and have not stopped being a presence in the community," Trently said. "We are there to be involved in all of our communities. We do major things and will continue to support Mahanoy City in any way we can. It's not like we're just picking up everything and forgetting about Mahanoy City. That's not how we do things at Service Electric."
Mayor Nancy Petritsch expressed sadness in the loss of another borough business.
"I understand they (Service Electric) are looking at business growth and their potential for growth, however, I do feel saddened that after all these years they find it necessary to leave Mahanoy City. I wish them success in their move."
