Question about JVC Televison & Video

1 Answer

I have a JVC AV-48P776. TV refuses to turn on after power outage.

I have a JVC AV-48P776. The power flicked off in my house with the tv running. Now the tv will not turn on. No indicator lights or any sounds when I attempt to turn it on.

    I checked the fuse (printed under it was F801 125V 7A). It unfortunately looks fine clear glass and the wire appears to be intact. The power cord itself seems good as well. I simply used an electric tester on where the cord enters the tv and it shows power.

    No, the light doesn't light up on the front of the tv either. Don't think I feel comfortable messing around on the power board. Sounds like I'm gonna have to have someone look at it. Figured it was worth a try to see if there was something I could do. Thanks for all your help, much appreciated.

This is a model first made in 2005. Follow the ac power cord into the set (unplug it first from the wall etc) and it will lead you to the glass fuse. JVC QMFZ049-5R0Z-E F905 FUSE, 5A 125VThis is the part number and F905 will be printed on the board next to the fuse which is 5 amp. If you are lucky the fuse just got surged out when the power came back. Some advice--do not buy a "generic" fuse like at Radio Shack--they will not work most of the time and blow for no reason--this fuse looks normal but you want one like it that is slow blow or thermal--most TV shops or parts dealers will have something not generic--brands like littlefuse etc. Check the fuse first--if it is blackened or the wire inside the glass broken you have found your likely problem. If the fuse is good further testing with a volt meter will be needed. Let me know what you find---I am here to help. SD TECH

    This may be beyond a do it yourself repair--what is needed here is to go further into the power board and see if voltages are present--

    Does the power light on the front of the set not even light up?

    If possible look for a shop that does JVC authorized repairs--they will have access to schematics and info on the JVC technical site---small shops will not have this and may only guess as to what the problem is.

    I will be here if you need help or advice.

Tv wont power up makes a noise but no picture

Your power transformer is likely shot. It'll cost at least $200 to have it replaced. Someone can come to your house to diagnose it. Usually costs around $65.
