Posted about this set last July when it was slow to turn on but otherwise operated normally. The turn on time got worse so opened it up to find swollen capXon. Put it aside until recently I recapped the PSU tand reassembled for testing - still no turn on just a steady red standby light but all voltages were up on the PSU . 24v reads 23.8 , 12v reads 13 , 5v reads 5.2 apart from on/off 4.6 and led lead has 89v. So the PSon has worked but nothing else as main is not sending BLon an Adj voltages nor anything to T-con. I forced backlight on no problem so I'm happy PSU is OK.
The main is T.MSD306.69A 12023 and screen T500XVN01.0 and this main is used in many different branded sets including Bush Teac etc and has a history of eeprom problems as kits are advertised. I checked obvious things on main such as 3.3v to u8 and 1117 regulators reading correctly. Just seems that main processor isn't completing the turn on as the red standby doesn't change to green and set unresponsive to any button or to remote. Have tried heat, freeze, short pins 5 6 on eeprom but no change. Of course no firmware support found.
Does anyone have any input re this main or advice or suggestion ?
