Sony kdl55hx800 red light blinking 2 times


Expert: Shahid replied 2 years ago.
OK, 2 times red blinking light shows problem with main power supply board that isn't working and need to be replaced in TV.
Power supply board has two type or supply, one is called standby power and other is main power, main power supply isn't working for some reason like defective regulator chip etc so TV shows that red blinking error code.
Power supply board replacement would resolve the problem.

you might need to have voltage checking at this time. if their is a dc output voltages at the power supply board.if none the main board will not turn on.then probably their is bad component at the power supply board.

Toshiba 42wh38b Projection TV won't come out of standby


That problem is usually have 2 causes..Its either power supply board or main board..

Please take this steps on how to determine the problem:
1. Open the back cover.
2. Check the power supply output...It should have 5vdc for the main board..12vdc or 16vdc for the audio and 24vdc for the back-light inverter..
3. If those 3 voltage supplies have encountered voltage drop...The problem could be on power supply board..
4. If the power supply output is normal..The problem could be on the main board...
5. If the problem is power supply you should check if the capacitors are bulged on the top and try to replaced it..If you can't do that you can purchased new power supply board..
6. If the problem is on main board there is no D.I.Y repair on that so you need to buy a new main board that fits to your TV..
Hope this solution will be helpful..

My phillips 60 inch tv 60pl9200d/37 wont turn on the power button flashes blue


Look in the manual. (Page 4)

Turn the TV on From main supply: Ensure that the main supply is turned on. A blue indicator light on the front of the TV lights up. When the TV is turned on by the main supply, the blue indicator light will blink for 45 seconds. This is the lamp's start-up period. When the light goes off, press the POWER button on the remote control or power switch. Press POWER to turn on the TV.

Power light flashes red 6 times. No picture.


The common fault often points the problem being to the power supply or the main printed circuit board.
If you are tech-savvy, you can open the back of the unit and measure, using a multimeter, the voltages from the power supply printed circuit board as well as the main printed circuit board, if the power supply is sending insufficient voltages, its common that you will get the flashing red lights.
Also check for any blown capacitors on the power supply as well as any shorted resistors. I hope this helps.

Green light comes on


Most Mitsubishi sets have a feature known as error code operational check. First up unplug the set and replug it. Press and hold the "Device" and "Menu" buttons for 5 seconds. You wil see a series of blinks a 1/2 second pause and another series of blinks. COunt the blinks before and after the pause and let me know. If its an issue other than power supply then you should get an error code. Power supply is the only thing that the operation check does not check.
