Philips TV, Model # 50PL9126D/37

We turn the TV on the blue power light on the front turns on, everything is fine for about 15 seconds then the screen goes black and 2 red lights (the lamp and temperature lights) come on the power button. The sound is fine but there is no picture. My husband opened up the TV and found that the lamp comes on, gets brighter and then just shuts down. I need to know what exactly the problem is as I wouldn't think it to be the lamp alone as it comes on and gets bright. I am just praying it is not the lamp engine because then we are talking $900 to fix.

Check to make sure all the ventilation opening on the tv arent plugged. if not, then you will have to make sure all the fans inside the tv are working properly.

I have a Philips 50PL9126D/37. I began having my screen go black (audio still playing) and a red light appeared in my blue power button. I removed the back of the television and checked the lamp, which was...

You cooould have a bad ballast, but it's probably either that you put the lamp in wrong, or you have a defective lamp though. There's a 33% chance that any of those are the case. Unplug the TV for 30 seconds. Plug it back in. Try turning it on again. Make sure you didn't over tighten the lamp during install. Especially the screw on the side. It should be a tight connection. Send the lamp back and get a new one. Usually they come with a warranty. If the new one doesn't work, it's either the ballast, or the power supply.

This is a plasma unit and philips plasma's are nortorious for bad power supplys, your problem may very well be the power suppy in the television, it is possible you blew a low B+ fuse on the power supply. There is also a issue with the Y-sustain board failing in this model, If you open the back and looking at the unit from the rear the y board is on the left side of the unit and the PS is in the center. disconnect the Y-sustain power plug from the power supply and turn on the unit if the unit stays on with no red light then the y board is bad. it does the same then replace the Power Supply.

42' plasma magnavox model # 42MF230A has no picture and no sound

I had the same problem with an Insignia 42" 1080p. Turn off the tv power and disconnect all cables (i started with power cable, then HD cables then HDMI). Wait 30 seconds with nothing plugged in, then I plugged everything back in (in reverse order) and it works fine.

Philips 50 Inch Plasma Model 50PF7320A/37 will not turn on

Commonly it's going to be a power supply related problem. The two boards that need to be looked at is the Main Power Supply Board or the power supply board for the screen. The one that powers the screen, some manufactures call it a Backlight Inverter Board.
If you have some electronic experience, you can sometimes find a Service Manual for the TV over the internet for less than $20. It will have the all resource material for repairing your TV model. It's just the matter of replacing the bad part on the circuit board.

Philips 42PF9956/37 Plasma TV - Looking for y sustain board

it isnt the Y-SUS board, it is the Power supply, iv fixed this exact problem twice in the last month, try turning the tv on, and when it turns green, unplug it real fast, while light is still green, after 15 seconds plug it back in, then hit the power button, if it dont come on, hit the power button again, this time, as soon as it turns off, hit the power button again to turn back on, sometimes you can trick the tv and it will turn on, at least i was able to do it, and once it comes on, it should work fine, untill you turn it off again.
