What's the cost to fix a cold solder joint? our tv picture will cut out and on/off red light blinks as well.

SOURCE: Picture and sound does not always come "on"

Trimmer, you`ve narrowed it down to a certain section and your absolutely correct that it is a bad solder joint, there are 2 things you can do, first get a bright light and a magnifying glass and go over the bottom of the board and look for it, should be fairly obvious with the magnifier, if not go here and order a can of "Freeze mist" www.partstore.com this is a great "tool" for finding intermittents, it`s coolant in a spray can, have someone watch the screen while you spray in the area of the intermittent, when you hit the bad part the set will work, re-solder the part and any joints around it that look bad, end of problem, good luck with it, BMW Rider

SOURCE: No picture; black screen; only red light blinking.

take to a service station i think just changing the displsy IC would do . but check in service centre

Sounds like a cold solder joint somewhere.

This may seem like silly answers but...
1. Be sure the power supply is plugged in all the way and that it is not damaged anywhere on the cord all the way up to the TV.
2. Be sure the Sleep Timer is not activated. You wouldn't believe how many times this is actually the case.
If these end up not the case then it is very possible that the safety circuitry in your TV's board could be going out. The TV is shutting it down due to it finding a problem with the circuitry in the TV. Most of the time people choose to replace the TV with a newer model as it is just cheaper to replace it than to have it repaired. This usually only happens in older TV's although I have seen it in TV's as little as 4 years old.

Testimonial: "Thanks 4 your help. I kinda figured I would need to replace the set, considering I had it close to 15 yrs. but I wanted to hold off spending the $$$."
