Question about RCA L32WD12 32 in. LCD HDTV
I used my TV last week for about 4 hours, left for about 8 hours, came back to use it again, and the unit would turn on, but wouldn't power up to the green "on" status, and would turn back to stand by after a minute or so. I tried to let it discharge for well over 12 hours and still nothing. Any ideas?
Hello Big Bristow, It sounds like you may have a shutdown problem. This will require troubleshooting of the television. I must ask if you have experience in electronics, I ask because this is what you will need to troubleshoot this problem: a schematic of the television (to know the correct voltages, signals and signal levels) a multimeter to measure continuity of fuses, and the voltage level to match with the schematic values. an oscilloscope to measure the signals and signal levels and compare them to the schematic values a high voltage probe to measure the high voltage points on the set. These are the basic pieces of equipment needed, in the more advanced are you will need a NTSC signal generator (the Sencore VA62A Universal Video Analyzer does a good job). If you dod not have a background in electronics I would not advise you doing any work on this set and you should take it to a TV repair shop.
