Question about Toshiba 27A50 TV
Red light flashes on front of TV. When tapping on the main pc board componets near the center on the board area the pic and sound comes back. Sometimes the TV will work for hours without a problem. I believe the intermittent issue is a cold joint. If someone can find the cold joint on the board that would be great!
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
