Thanks for the info Ron. I have seen those kits. I already did the main 3. Looks like i will order the rest of the caps and the 2 diodes this weekend and give it a try.

Hi Mavrick2k,
did you resolve this ? I'm at the stage of replacing the Zeners ZD904 and ZD902, I'm also replacing the rectifier STPS40H100CW, Dual Schottky Diode, 40A 100V Common Cathode, Dual, 3-Pin, TO-247 at D922, I've ordered most of the caps as well.....getting fed up with this PSU....seems like its a common fault, just wondered if there was a iron clad fix for it....other than trial and error

Re: Philips 42" 715T2432-2 issues

I had not reordered parts. I got busy and had not had time and then i did some more research. Seems like people do get it running again by replacing majority of caps and zd902&904. One post had stated the Q902 - Shorted. Got a new meter that did capacitance so tried testing a few caps. pulled five off the board and all five tested bad. Then tested with a friends meter with the same. Thought about getting a esr meter but dont want to spend the money for as little as i would use it. I tested 922 and got a short. So I am putting in the order now for 11 caps 2 diodes and that rectifier.

Re: Philips 42" 715T2432-2 issues

I've resolved the issue with the power supply I had, same issue chirping on startup/load I've replaced the following parts and now have a working PSU

C953,C952,C951, C955, and the big 220uf 450V cap

ZD904, ZD902

D922

(5 caps 2 Zdiodes 1 rectifier beats your 11 caps 2 Zdiodes and rectifier ....<grin>)


Just thought I'd pass on my success on this repair (your mileage may vary)

I've got to say I'm appalled at Phillips the company they are about as much use as a chocolate fireguard when it comes to helping the end user.....that's the problem these days with this throw away society we live in .....its' a shame

I orderd 11 caps because i figured to go ahead and get rid of all the crapxcon while i was at it. I did not order the big one though and I did not test it. Was yours bad or did you replace it just because. I prolly should have ordered it as well.

the problem i have traced down is the zd906......spray it with a can of air upside down and it should change the chirping sound. and thats the problem. fixed my tv
