Question about Toshiba 43HX70 43" Rear Projection Television

1 Answer

TV turns off and power light blinks

My Toshiba 43H70 will turn on for about 30 seconds, then click off. The power light will then blink slowly. About 2 seconds off 2 seconds on etc. It will then not turn on any more until I unplug the TV and wait about 20 minutes to plug it back in. It then repeats the same thing...

Hi


Thanks for using FixYa. Clicking sound can be from a bad capacitor on the power supply board. To start with open the back of the unit and check the power supply board for any blown capacitors. Also check the flyback as it can be some loose wires in the coil. Usually this happens when there is a vibration in the horizontal circuit, the flyback and/or coil can make this noise. Also inspect the fuse if they are working fine and please make sure to turn off and unplug the TV for at least 1 hour (this will drain off current from all components especially capacitors) before you perform any repairs. Opening the unit is only recommended if you have some electrical expertise. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

Hello

If the power light blinks slowly,

you've tried to turn on the TV during

the lamp cooldown cycle. Wait

approximately 30 seconds, and the TV
will turn on automatically.

If light blinks, pauses for about a

minute, and blinks again: the lamp is

trying to turn on (TV will turn on

when successful). If TV doesn't turn

on and sequence continues, the lamp also
needs to be replaced.

To order lamp call 1-800-338-0376.

Have your TV serial number

and lamp type available (you'll

find this information on the

sticker that's on the right side of
the TV).
OK.

My toshiba 42HL167 won't turn on


Try this fix from the toshiba website. Q. I have no picture or sound, but I have a blinking power light?
Models: LCD-2007
REF:FAQLCD00090
1. Try resetting the TV by disconnecting the power for 30 seconds and then plugging it back in. If this has no
effect, try moving the TV to a different power outlet that has been tested and is known to be good.
2. If your unit continues to fail, please contact our Customer Solutions Department at 1-800-631-3811 Monday
through Friday, from 8 a.m. until 7 pm CST for a local Toshiba Authorize Service Station Hope this helps you with your problem.

TV turns off by itself after being on for 60 seconds


Led blinking Three times means B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.
Hope this helps.

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!!!!
