Question about Toshiba 43HX70 43" Rear Projection Television
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...
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.

Tips for a great answer:
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.

Have your TV serial number
and lamp type available (you'll
find this information on the
sticker that's on the right side of
