Question about Toshiba 42HM66 42" Projection HDTV
I turn on the TV and it makes a low squealing noise for about 45-60 sec. when it wams up operates just fine. Started this after 18 mo. of trouble free operation. Any suggestions?
If you can solder, try checking all the boards for poor solder connections. Resolder any that appear grainy or have rings. If that fails to resolve the problem, then we will have to start looking for failing capacitors in the power supply area.
Please note that there are potentially dangerous high voltages inside the set even when unplugged.
Keep us posted,
