There is an issue with the audio processor. Most likely it is the main board needs to be replaced in order to fix the issue. You will need to remove the back cover in order to get access to it.

There could also be an issue with the power supply supplying the right voltage to the processor. This can be checked by seeing if the 18V DC is present at pins 3 and 4 of CN90 on the power supply. If the voltage is present, then replace the main board. If it is not, replace the power supply.

You have the television on sleep mode. You'll have to disengage the sleep function! Most tv have this option so that you can go ahead and snooze for a while and the tv will turn itself off!

I would check the capicitors on the power supply to see if the they are bulging at the top or leaking. I had a Samsung lcd that starting taking and hour to turn on then eventually it would not turn on. So I checked the power supply and saw four bulging capacitors that I replaced and now it's working like new.

Tv will not come on . Only red light that blinks three times.


Hi, you are having a problem with the STR-W6765 Primary Switching Regulator located on the power board. You can either solder this regulator on to the power board for 10 bucks or replace the power board.

TV has gone into "protect mode" to do just that to protect against the damaging failure that has been detected, you will need a servicer to diagnose the failure. Good luck and Merry Christmas!

I have a large projection toshiba tv. When I turn it on the red light indicator blinks but tv screen does not go on. Please help and let me know what I am doing wrong. Thank you.


one thing you may try first is disconecting the tv from ac outlet and plug back in ater 20-30 seconds, try to power back on. If nothing happens you're not doing anything wrong it might be that the tv needs circuit repair, the light blinks and you get sound indicateds a possible deflection board problem either horiz out transistor or surrounding circuit if you only get the blinking light no pix or sound could be also indicator of defl circuit failure or switching mode power supply acting up.hope this helps please let this site know if your question was answered.
