Philips Plasma 50PFP5332D/37 won't turn on red light blinks 6 times...

[reed]

Hello Everyone,
I am having a problem with my Philips Plasma 50PFP5332D/37.
Power on blue light comes on, you hear a click and then red light flashes 6 times.
I found a problem fuse on power supply board and replaced it with new one. Powered on and blew fuse right away with same red flashing light Now I am stumped! I took a pic of the board and put a red arrow pointing to the problem fuse. Does anyone have any advice on how to troubleshoot or best guess problem from experience? Any help greatly appreciated

Welcome aboard!! Something obviously popping that fuse. An old trick that you can try.........you will need a handful of those fuses to test. As you can see your power supply board is feeding several boards in your tv (audio, y-sust, z-sust, logic card etc...

What you can do is replace the fuse again. This time before powering the tv on, unplug one of the cables that feed another board. Then power it up and see if the fuse pops. If it does re-plug that board in and move onto the next one. With any luck at all you will be able to pinpoint what board is setting off your power supply. It will cost you a few fuses to conduct this test but may be worth it. A bad y or z sust could cause your issue. Seriously doubt an audio card or logic board would cause this. I would start with the sustain boards.

Thanks I'll stock up on some fuses and try that. Hopefully i'll have some good news to post soon!

unplug the y-main first; its is most likely the issue... these and the 42 inchers have the same issues... it most likely has samsung guts and LJ92-xxxxx y-buffers...

If its your Y-main & Buffers
I'd send it to Coppell... Only because its a 50incher; if it was a 42 id say part it out...

Yea funny I was just reading about that on the Coppell website last night. I'm not seeing any burnt areas on the boards but wont know until I find out which board is the problem. After reading up on Coppell i'm hoping its not an issue with the logic board uhh, at that point it would be a boat anchor lol

I doubt you have a sustain board fault. The sustain boards failing rarely blow a primary side fuse, the SMPS is current limited. You probably have some shorted transistors on the PSU after that fuse.

My tv has a blue light flashes 6 times then 5 quick times. It was alright. Like it was black and white. But now it's all pitch black. What do I do ?

Do you recall what type of fuse it was? I'm having the same issue, and would like to have some on hand before I have to pull that mammoth off the wall

You have shorted fets that are blowing the fuse, you need to test the parts on heatsinks before changing the fuse.
