Check the power board, capacitors seem to be possibly faulty on this model. TV will need to be taken apart.

Model PJ556D will run for a few minutes and then shuts off. Once it cools down it will start back up, but shuts off again a few minutes later.


Hello, Greg.

The most common reasons are the temperature is too high or the ventilation holes are blocked.

Unplug the AC power cord, wait 5 or 10 minutes then turn back on.

There could be dust or the air filter needs to be changed.

Take the lamp cover off the bottom. It's possible that the screws holding the lamp are loose.

Hope this helps.

Tv cuts off and green light flashes


If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.

Good luck!

T.V. TURNING OFF AFTER ABOUT 5 MINUTES.


Go to Samsung.com for solution. There is a switch that just needs to be repositioned behind access door on rear. Fixed my HL-S5086W ok.

Viewsonic N3000w LCD TV randomly shuts off...


It seems that the power fails quite often with this one burning the Inverter boards transformers. OZ960G chip may not be broken, so try getting a new power from somewhere. Measure the transformers. suppose to be somewhat 5 ohms. tolerance is +-1.5 ohm. of more, replace.
