Re: 42" Philips-Won't turn on
So y'all think it's relatively the same problem?

Re: 42" Philips-Won't turn on
Yes.
These are bad capacitors:
http://www.google.com/imgres?imgurl=...w=1024&bih=667
You can see how the tops of them are pointed, when they should be flat.
Take off the back panel of your TV, and check the capacitors.
If any of them have a rounded top, they are bad!
Capacitors are can-like things that look like towers on the circuit boards.
While the cover is off the TV, it would be a good idea to take some pictures of the circuit boards.

Re: 42" Philips-Won't turn on
Appreciate that Ben, yea I did TV repair for close to 15 yrs, but about as many years ago. Then they didn't have flat screens then, but I'm pretty sure the block diagram/flow chart is pretty much the same. Also caps don't have to have rounded tops to be bad or leaky and screw things up. Jumping them with a good cap will sometimes show them but you have to be careful what circuit your doing that in as it can make things worse. Best things is just replace caps in RC timing circuits which is where I'm pretty sure this will be. Primarily the electrolytics.Yes.

Mine at present is back to working so I have to wait for the problem to arise again. I really would like to hear back from grizzly with some pics and really really if he gets it repaired.

Re: 42" Philips-Won't turn on
Here are a couple of threads already started on this TV. You may find what you need here. If you have anything to add, add it in one of the threads of that model number.

Re: 42" Philips-Won't turn on
Sorry if I am jumping in on the wrong thread here but,, I replaced the 3 caps on my 42PFL5432D power supply board,, and still I am getting this squeaking about every 1 sec, and of course no picture. Any thoughts. Its very difficult to locate the squeak but I think it is from the center transformer,,just not sure.Comment

Re: 42" Philips-Won't turn on
Multiple posts of the same problem in different threads is a good way to get ignored. Failing to give meaningful information increases the odds.
1. Where are the pictures of YOUR power supply?
2. Which caps did you replace?
3. What brand and series of caps did you use?
4. What were the original symptoms?
5. What are the output voltages of the supply?

To all the members here...
Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.
So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But... -
Hello, I have an Acer Aspire 4520 from a couple of decades ago and I want to repair it solely for nostalgia.
It happens that when I turn it on after having been disconnected for a long time, it turns on without problems, it tells me that the BIOS has been reset and that it will load the factory settings, if I tell it to continue, the computer turns on and everything works fine.
The moment I turn it off and want to turn it back on a second time, or restart it and try to start it again, it no longer gives an image, and it no longer responds.
If I remove the... -
Hi everyone,
I am dealing with the problem of turning on and off my Dell e7470 notebook.
The battery charge light is solid white, I press the button, the power indicator and the light on the button are solid for 1-2 seconds and immediately turn off.
The system does not turn on, there is no post.
I removed the RAMs and changed them, changed the battery, RTC battery, AC adapter, removed them and waited, tried again, it does not turn on.
The problem continues in the same way.
I tried to turn on the Fn key, nothing came to the screen.... -
