Question about Televison & Video

1 Answer

I was watching TV and suddenly the screen went black. No picture, no sound. On/off timer LED on TV started blinking. I could not turn it on (or off) with remote or ON switch on TV. I found that if I unplug and plug power cord TV comes on for a couple of seconds (I can hear the sound immediately and picture starts to come on) but it TV screen goes black in a couple of seconds, no sound, and on/off timer LED blinks. Basically, TV is ON, but I cannot do anything with remote or manual buttons on TV unless I plug and unplug the power cord in which case TV comes on for few seconds before ON/OFF timer LED comes on. I found that during those two seconds if I push power swich on TV it shuts off TV and on/off timer stops blinking. Now I can turn TV ON with my remote. But as soon as I turn it on, TV shuts off in a couple of seconds and you know rest of the story. I never moved this set since I bought this TV few years ago! I always had a surge protector. What do you suggest to repair?

    This was JVC model JVC AV-32F734, not Flat panel TV. I bought it in 2004. I understand that this is frequent problem with many JVC TVs based on complaints I read online. I can do some basic soldering. Does this change your recommendation? Where do I get service manual?

The television is shutting itself off to protect itself. The blinking light is a code pattern. The specific code determines whether or not you need an LCD Controller Unit, Main Board, power supply or something else. You would need the service manual. There are parts distributors you can get it from and the parts as well. If soldering and tv repair is not something you are entirely familiar you may want to seek a tv repair person. The manufacturer's support may walk you through the service menus to complete a factory reset depending upon the symptoms.

    The service manual on CD Rom and the parts can be purchased from herehttp://www.partstore.com/Model/Matsushit...
    Probably needs a crt tube socket board and (hopefully not) a main board.

    Would you know the range of cost of repair, or should I just junk it and look for new one? If it costs $250 to repair, I can get new one for probably $450 for 37 inch flat panel with about the same viewing area. Could it be just resetting the TV and can be fixed without hardware fix?

    CRT TVs are reset by unplugging them for 3 hours. There usually isn't a way to reset them. However you would know that for certain with the CD Rom. If there is a reset according to the CD Rom and it doesn't work than the cost of repair would most likely exceed $250.

LG 42PC!R Plasma TV turns on and then green led blinking with no ppicture and sound !


Your problem is most likely a fried circuit board. I always connect my good electronic to a back up battery. but your problem might have been storm or surge related, I would take it to a repair center and get an estimate.
