To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Check connector P11 and SS11 and make sure they are not loose. If they check fine, disconnect the connectors from the power board and che connector P1 and P11 for shorts. If you found a short, then replace the power board. If no short, then check SS11 for a short and replace that board if needed.

Toshiba 50hp95 will not respond and has flashing red power light. It seems many people have this problem, what's the solution? We have tried all the Toshiba suggestions.


My 50hp95 had the same problem; the red power light is flashing and the tv will not turn on. I unplug the power and plug it back in and the TV clicks, but the power light continues to flash red. My problem was a bad Seine module which you can bypass if you do not need to watch HD off air programming. Since I get my HD from the cable, I can bypass it. All you need to do is remove the back panel from the TV (unplug the TV first) and on the main circuit board unplug the white connector labeled PJ63A. The main circuit board is the one in the center of the TV and the PJ63A connector is the bottom white connector on the left side of the main circuit board (the label is printed in white on the circuit board under the connector). Once I plugged the TV back in it worked immediately.

My tv


Try unplugging it for 1 minute, replug, and see what happens.

If the above doesn't work, and If the TV simply fell hard and now you have the blinking red light there is a good chance you simply knocked out one of the main power connectors to the main board. Alas, there is also a chance you broke a connector too, but you won't know without opening the box.

If you are out of warranty and don't mind opening your LCD TV, you can open the rear and check for loose cables, or even a dislodged fuse.

The above is the easiest thing you can do.

Color/Pic problems Mits WD-65731


it sounds as though there is a problem on the main board and yes,it will be expensive to repair.i would guess between 400 to 600 possibly more depending on how much damage is on the main board. i know this isnt what you want to hear but i have a friend that has a tv repair shop and i know he gets big money for repairs on big screens.
