Re: tv won't turn on

Your problem could be the Convergence board is loading down the power supplies and will not let the TV set come on, or the power/deflection board, part number AA94-08574A, or the STR type regulator IC, part number AA13-00105A. If you locate the convergence board, unplug the connectors, and see if the set will come on. if the set does come on, replace both of the STK convergence IC's at once. The part numbers for those IC's are STK392-40. You can get the original replacement IC's from MCM electronics for about 15 to 16 bucks a piece. Do not use the less expensive STK IC's as they are not the same. the replacement IC's should have the name of SANYO printed right on the face of the IC's. Good Luck

Re: tv won't turn on

How do i locate a schematic of this tv? I probably know just enough to get me in trouble but i'm not in a position to hire someone to fix so it's either me or trash. I have the same problem but don't know which board is the convergence?? thanks

Re: tv won't turn on

Hey technman,
Thanks for the instructions. In my case the power did not come on after I unplugged the connectors on the convergence board. Do I need to replace both the power/deflection board and STR type regulator IC or just one of the two?

Trying to replace lamp in HDTV and having trouble. Does not function correctly after putting in new bulb. Boots up and then visuals go black and the green power light keeps flashing. Help?

Panasonic DLP TV Bulbs

Make sure its an original Osram or Philips bulb inside the housing. If its a cheap lamp it will act this way. If it is an original lamp, then you may have a power supply issue. It shouldn't affect your TV but you may want to try resetting the lamp timer by following the instructions that came with the lamp.

Tv won't turn on only a red timer light appears when the power is pushed on

First press on the power button on the tv remote control. if it is also not solved then i think your tv has a internal hardware problem which may be failure of some electronic components. It will be better to take it to nearest service center

Timer light is flashing but tv wont turn on!

When the timer light stoped flashing the remote control would not turn on the TV. The next time the light quit flashing I held the power button in on the TV for about 5 seconds and it came on and has had no problems since then with the remote or the local TV power button.
