Question about RCA HD56W66 56" HDTV
I read from a post that you fix about 10 of these RCA HD56W66 projection tv's a week. I am having a problem with mine where it won't turn on. I plug it in, the green light comes on and I can hear the tv starting to turn on, and then after about 2 seconds it shuts back off and won't turn on again until I unplug it and plug it back in, and then it does the same thing. I am a former military electronics tech turned civilian geek (network/system admin) so with the proper manual/instruction I can fix about anything, I just have no manual or schematics for this. The nearest repair shop for me can't make it down to me until New Years Eve and that's just to do an initial diagnostic, not even to necessarily fix it. Is this something you have seen before and do you have any suggestions for me? Any help would be greatly appreciated.
You hear what? is this sound a high voltage static? The fact that you have flashing light means the main fuse is good and your processor is receving power. THe processor is detecting a shutdown situation that causing it to shut down for safety. high voltage situations are the primary causes. but it can be one of about 20 conditions. at the shop we have a computer that reads error codes much like a autombile. the primary things to check for are a shorted horizontal output transisitor. if you hear a high voltage static then it means you tubes are trying to fire but are drawing to much current.
