After a nearby lightening strike, I have no picture or audio on my phillips 32pfl5332d37. when powered up the blue and red light come on together and go off. Then the red light blinks slow then fast, pauses, and repeats slow/fast, over and over. is it the power board that is out?
Optional Information: Make: phillips Model: 32pfl5332d37 Already Tried: power down and up several times. removed back and looked around. Tested fuse.
Hi!
Have you tested any of the DC voltages going from the power supply to the main board?
Tim
no
Can you do this?
I have a volt tester but am not comfortable opening the back while tv is plugged in. wouldn't know which wire to test but I think I can identify the main board and the power board. Is there a board I can just change out?
Ok well the problem you have is that you could have a bad power supply or a bad main board. Chances are its the power supply but not guarantee. If you want to shotgun it and gamble the $120 for a new power supply you can, if you click HERE, it will bring you to a page where you can order it.
If the board looks okay, could it still be damaged? Both boards look okay. is there a simple instruction or diagram you could share where I can see where to test DC power and other things to test .....if this gives an answer?Doesn't the blinking pattern indicate a certain problem?
Yes it can look perfect and still be bad.
To test the DC voltages, you do this on the wires between the power supply and the main board.
Yes, but it is generic, it could mean a bad main board or a bad power supply.
What should the dc voltage be on each wire? do I test them where the emerge and enter the boards?How do I change out the power board? I saw 3 screws, a plastic clip, and 2 or 3 wire assemblies. is that all there is to it? What are the odds it is the power supply board alone?
You should get 5v, 3.3v, 12v. Yes, you check them at the connector where they come out.
Yes, just a few screws.
I would say 75%.
