Re: Philips 42PFL5432D/37 PS 715T2432-3
Well i figured out my problem. Could not figure out how most of the components on the 24V side seemed shorted. Started to remove them and they all tested goo out of circuit. Knew something went fishy. Traced it back to that rectifier. Some dumbass (being me) when replacing the rectifier removed all old thermal paste to replace with new nicer compound. What they forgot to do was put the plastic isolator back between it and the heat sink. Since the back is metal and the heat sink is grounded out it created my short on the whole 24V side. Put...

Re: Philips 42PFL5432D/37 PS 715T2432-3
Dont think i would need the Q902 after testing again. Saw someone else had replaced it. Just getting to the point I will try just about anything.Leave a comment:

In green are the parts i have replaced. In red is what i am thinking about replacing. Plus at least two of the small diodes on the back of the board....Leave a comment:

Philips 42PFL5432D/37 PS 715T2432-3
Tried repairing this set already. Looked at common problems and threads related to these systems. I replaced all Aluminum caps including the high voltage, diodes ZD902 & ZD904, and rectifier D922. The set powered up fine went through menus and all was great. Bought a wall mount for bedroom, mounted and hooked it up and powered it on and got the chirping and no display again.
First time through i debated replacing D926 because it was only showing around 200 with the meter but did not. It is now showing dead. D922 that i replaced is also showing shorted again along with d927.

Re: Philips 42" 715T2432-2 issues
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.Leave a comment:

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...Leave a comment:

Re: Phillips 42PFL5432D/37 Chirping and No Picture
I am working on this same tv. started with just the visibly blown caps. thought about replacing the 4th big one but didn't. no fix and with chirping. I just picked up a new meter that does capacitance and diodes. I pulled 5 caps off the board including the 3 that i just replaced (which look fine) and tested them with my new meter and then a friends meter they all 5 show open loop. Is this normal? Secondly i went through and tested all the diodes. I also get that D912 is bad. ZD902 shows good and ZD904 seemed a little low but still...Leave a comment:

Re: Philips 42" 715T2432-2 issues
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.Leave a comment:

Re: Philips 42" 715T2432-2 issues
has anyone traced the source of this problem down or even replaced the whole power board and get the tv working again. I am looking at this issue now. replaced the 3 caps and now getting chirping. dont want to waste time tracing down everything else on the board if this many people have not gotten it fixed. would be nice to know if replacing the entire board would fix it too.Leave a comment:
