Lost Picture
I am loosing the picture on my JVC AV-27730. It makes a little crackle
sound and would come back when I would slap the set on the side. This worked for a few weeks but no more. I took the back off and if you flex the main board with a little pressure the picture will come back for a while but not long. I am being careful to not touch anything where I can be shocked. (I think.) Thanks for any help. |

Most often it's caused by a bad solder joint. Use a magnifying glass to look for it. Start in the main power supply and the high voltahe sections. If you don't know how to do this, find a technician or TV repair shop. If it's only a loose connection, it will probably cost you just the standard labor charge with no parts. If you allow the symptom to continue, parts mey be damaged, making the problem most costly to repair - because the technician will need to find and replace the bad component(s) and find the original loose connection that caused it. |

Thanks to you in helping me to diagnosis the problem with my JVC TV picture.
I just got around to examining the board and found the culprit. I resoldered the joint and now I have a picture. Thanks again, Harry "Harry" wrote in message ...
