Question about Toshiba 61HX70 61" Rear Projection Television

1 Answer

Power shut off

My Tv will shut off, and the power light blinks. After being unplugged for 2 days it came back on and didn't do it shut off again for a week. Then it did it once again 3 days later. I originaly had plugged into a power strip. It is now plugged directly to outlet. The repairman doesn't have any idea what causes this, when he was looked at the Tv it was working fine and couldn't get to shut off. Any suggestions? Thanks, Jason

Theres an STR##### IC in the power supply thats intermittant and this is a very very common problem Im surprised the repairman didnt know this. Tell them to look it up on the schematic and come to your house and replace it. Most repairers wont do this in the house because they cant get the same money but in my opinon it shouldnt take more then an hour too do. Good luck Ps the ###### in the STR number are differant on differant models.

Our Mitsubishi projection tv went out one day. When we went to turn it back on all it does is blink the green light for a few seconds and then shuts off. What could it be? Where can we look to see where...


MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ONFOR A MOMENT AND GOES OFF.

PRESS AND HOLD "device"(input) and "menu"buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and twoblinks--this is the most common and easiest to fix.

Sony KDF-50E2000 shuts down and blinks repeatedly twice.


The 2 blink error is a temperature error and the 6 blink error is a thermal fuse error. You may need to unplug the set and get you a can of canned air, take off the back lower cover and blow out all of the fans inside the set.

TV turns off and power light blinks unpluged andd still does it.


Likely to be the STK convergence chips causing a protection circuit to switch the TV off. Have you got any onscreen convergence problems (i.e, colour fringes)?

TV auto shut off-power indicator light blinking-won't turn back on


You could have gotten an electrical surge that put your set into a shutdown condition and unplugging the set and letting the Microprocessor reset will fix this problem if it dosent blow out the main power regulator as you still or might I say have a regulator IC problem. IF THIS PROBLEM HAPPENS AGAIN MORE THEN A FEW TIMES WITHIN A SMALL TIME FRAME I WOULD HAVE THE SET LOOKED AT BEFORE THE REGULAOR BLOWS SOMETHING OUT!!!!
