That is the sign of bad caps, open up the back and look at the caps in the power supply, when caps have high ESR, the ESR will go down when it is heat up. I use hair dryer for a lot of troubleshooting for 30 years. Bad caps can look normal with no sign of leaking/bulging.

Make and model?

Hdtv flashing green light for timer tv wont turn on


If the TV is a few years old the flashing green light means the bulb need to be replaced. That's why the TV will not show a picture. Check your owners manual on how to replace.

It sounds you need a new Projection Lamp; they usually last for 2000 hours or more. The led blinking is the lamp warm-up period and it fails now, if you replace the lamp be careful very static sensitive and blow the dust out with air while the TV is open. Hope this Helps.

New bulb worked for a short trail run now wont light up. flashing green led colour wheel is turning on start up


when you changed the lamp, did you blow the dust out of the projector? if the screen on the side of the lamp is blocked (i.e. with dust), the lamp will blow quickly. if the projector were to overheat, by the fans not running or blocked vents, everything would shut down and the led would blink red.

My sony sxrd projection tv wont turn on


From what I've been able to find, the problem is the fan that cools the bulb is not starting when you turn the tv on. Blow on it to get it going or clean with compressed air. The fan could be clogged up with lint etc. It's on the rear left of the tv.

Hitachi 60sdx88b


The flashing red light means that the tv is in protection mode. The tv will not turn on when the red LED is flashing. The most common problem for Hitachi are the convergence output ic's. But they useually do not cause the LED to flash. This tv does also have a problem with Q777 going bad. This will cause the LED to flash. If Q777 is bad the horizontal circuit needs to be modified. This must be done by a tech.

TV randomely turns off


it may just be a static buildup from the dust.
open the tv and blow it out with a air compressor.
if that doest not work then the circuit may be overloading.
remember it stores a charge for days.
