Re: PHILIPS 42PFL5432D/37 Power Supply troubles

I have tested the pins from the power board to the main board and the pins going to both master and slave inverter boards. I don't see any capacitors that are bloated. Unfortunately, after two days of the tv running almost non stop, and always being plugged in, it has never malfunctioned. I am going to put it back together and wait for it to malfunction again. Thanks for all the help and I am sure I will be back.

Well I have voltage on the pins measured when the tv is working, but now that the tv is lying on the table with its back off it won't malfunction. A little frustrated by this, but I am starting to think that the fact that it won't malfunction while partially tore down might indicate the problem has to do with overheating. I am wondering if there is some other diagnostic step I should take while I wait for the tv to malfunction again?

retiredcaps,
Will do, one clarification: when you refer to measuring the pins when the tv is not working are you referring to the tv being turned off, or are you referring to when the tv is malfunctioning? Thanks

Here are some shots of the main board. I have a multimeter and can use it to measure DC (with a little help from the manual)....

It started about two weeks ago. The first time I noticed it the TV locked up while I was watching a show. The picture and sound were both still on, but you could not change channels or turn it off. The led light on the power button remained green and blinked when you tried to use the remote, indicating that the TV was picking up the infrared signal from the remote, but nothing changed. Eventually I had to unplug the TV to turn it off. When it was plugged back in, the TV worked correctly, until the next day. The next day the TV would...

I have the same model with a similar, if not the same, problem. My TV essentially locks up after 5 minutes to an hour. To get it to come back on you have to unplug it. I never got the chirping sound, but I got a high whistle for about 5 minutes and it went away. This all started about two weeks ago and this morning it just stopped. I figured I would see capacitors bulging or leaking. I took it apart and I don't see any swollen capacitors. I have attached pictures. Would you suggest which capacitors I should replace just as a shot in...
