Question about Mitsubishi WS-55857 55" Rear Projection Television

Mitsubishi WS-55857 55 Turns off

My rear projection TV turns off after 30 or so minutes. I have run a fan on the boards trying to cool it down, but it does not seem to take a difference. Any help?

Oh, I am not sure if its related, but the picture kinda pulses a little bit. I don't think there is a time correlation between when that happens and the TV turns off.

Thanks for any help,
~Eric

I have the same problem and it is costing me $300 to fix it. Not that big of a deal but a pain none-the-less. I'm sure we aren't the only ones that have found defects with this television set.

Sony grand wega randomly shuts off for about 15-30 seconds every 10 minutes. Fairly annoying


No lights?? Are all fans running properly? Check for dust buildup and clean out. Dust can slow down the fans enough to shut it down. Sounds like a cooling issue.

Have a Mitsubishi 52725 52" DLP The TV shuts off frequently. It tells you "the TV with shut off in 30 seconds". It seems warm but I have a fan in the rear to cool it down but sometimes it still...


does it give you the "airflow" message?
if so it needs a new thermal sensor by the lamp, known issue defective sensor..

if not, suspect bad capacitors
there are many bad caps across 3 board , all part of the chassis.
a repair center will ship the chassis into mits for rebuild, about 400 or 500 total bill

My 50 Viore dlp tv turns itself off after just a


HI, this may be a simple cooling issue. try inspecting the cooling fans that are located near the power sector. if these cooling devices are not operational, they will cause the power board to shut down periodically, due to heat build up.

If the fans are operational, this will confirm a weak and defective power power board.

Philips 51 rear projection


Thats a common problem with the DPTV300 through 355 chassis. You will either need to call in a repair tech for that type of troubleshooting, or replace the LSB circuit board ( Large Signal Board). You can get a replacement LSB circuit board at the following link for about half the price of what they actually cost. Here the link.

This is very common in Samsung DLPs. The DMD board may be going bad or it could be one of the fans that cool the engine while it is running is going bad (even though the fan looks like it is running, it is not running fast enough to cool the engine). Just before it shuts down your picture should read at the bottom of your screen which fan is bad. But I have found that does not alway happen.

Panasonic pt-52lcx65 picture problem


Have a sears technician come over ,call them and set up an appointment, they are the best techs out there for tv issues, they will come out even if you did not buy the tv from them. Most of the Sears tv techs come from Philips which closed down their tech shop a while back. It sounds like you have dirty or faulty fans on your board. please advice.
