Re: Philips 42PFL5432D/37

My apology to PlainBill! I checked the model and it's 42PFL7432D/37 chassis Q523.1U LA
I mixed up the 7432 with 5432. I am searching for the service manual, hope to find one soon.

The service manual is available from Elektrotanya; you have to search on the chassis number.

There are already several threads for that chassis; I suggest asking the mods to either move your posts to this thread or to open a new thread.

Re: Philips 42PFL5432D/37

Tracked my caps and found they were mis-delivered to another town, but only 10 miles away, so I went and got them. Now, caps in hand, ready to begin.......=-)
Looks like I have to take out the main power board before I start.

Not sure if you got any or not but Solder Wick is a great tool for desoldering the old caps, I have removed and replaced caps without solder wick but it's a pain and isn't as clean of a job as using the wick.

Re: Philips 42PFL5432D/37

backoi, there is something very strange going on here. I downloaded the service manual for the 42PFL5432D/37 and got the chassis illustrated below, which is a good match to the one PoteauPets is working on, but not at all like the pictures you posted.

What is the model number and chassis number of your TV?

Re: Philips 42PFL5432D/37

Still no caps today.

From all the feedback Digikey usually delivers in 2 days with USPS 1st class to USA residents.

Re: Philips 42PFL5432D/37

Did you change any of the caps on the power board?

All the caps look like Rubycon ("K" vent) and then there are 2 blue caps with the "+" vent.

Re: Philips 42PFL5432D/37

Dang it. Still no caps today. Ordered them Tuesday before noon, was hoping to have them today for sure..............=(

Re: Philips 42PFL5432D/37

The service manual is available from Elektrotanya. This TV uses a split power supply design that makes troubleshooting a LOT more interesting. I'd suggest downloading the service manual, Philips is excellent about supplying troubleshooting information. I'll be downloading a copy myself and be ready to help.

The fact that you have 24 volts to the inverter and the blue light goes on and off indicates both power supplies may be working. The first step is to check that. Since it does not appear the connectors are labeled, the manual is going to be a big help.

Re: Philips 42PFL5432D/37

1) Do you have a source hooked up like a DVD player to see if there is a picture and sound?

2) Does the power always go off after 1 minute?

a) If you turn off the TV and turn it back on, does it stay on 1 minute and go off again?

It can't be turned on. I tried to hold/release the power button on the side of the TV and sometimes, I was able to turn the unit on after hitting the power button few times, then the power button worked and I could turn it on/off as usual until I shut off the main power, then the problem re-occurred.

3) Can we get a picture of the entire TV backside so all the boards are in view? We want to see the relationship and cabling between boards.

See attached pictures.

4) PS. Sharp eyed readers and future people will notice this is why we always INSIST on photos on your own TV. The boards are completely different even though backoi says the models are the same in post #36.

1) Do you have a source hooked up like a DVD player to see if there is a picture and sound?

Yes, I have one. Since TV can't turn on, so the dvd wouldn't do anything.


2) Does the power always go off after 1 minute?

Yes, after pluggin in the main power cord, one of the LEDs on main board stayed on 1 min, then it went off at the same time with a blue indicator LED in front of TV. See attached pictures.

Re: Philips 42PFL5432D/37

Recently, it had no picture and no sound.

When power on, the blue light in front stays on for 1 minute, then goes off.

Re: Philips 42PFL5432D/37

Post clear focused top down pictures of YOUR boards using manage attachments and NOT inline. See my sig file in this thread for exact instructions and size guidelines.

Hi, I attach the pictures of power board, main board and inverter boards. Please let me know if any picture needs to be retaken for clarity. Thanks!

Re: Philips 42PFL5432D/37

Hi, I would start by going up to the beginning (the 1st page) of my posts and see how Retiredcaps has walked me thru everything step by step. It will help you to see what to check and what to look for until you find the problem.

Re: Philips 42PFL5432D/37

What else should I check?

Re: Philips 42PFL5432D/37

Hi, I am new to this forum. I have the same model TV. Recently, it had no picture and no sound. I checked the power to both inverters, measured 24V DC. Visually, I didn't see any sign of caps burned or deformed. When power on, the blue light in front stays on for 1 minute, then goes off. What else should I check? Thanks for help!

Re: Philips 42PFL5432D/37

Went to Radio Shack and got the iron and the solder that you had linked to me. Checked to be sure they were the right part number(s) also. They didn't have any extra tips though. He said they have to be ordered from their online store. So, now I wait anxiously for my caps to arrive.............lol
Yes, electronics do get cheaper each year but some things are still a little too high to just run out and replace. I think my cut-off point is just about at a 42" flat screen price...heheheh
Funny thing is......Right before I found this site and learned about "bad caps" I had searched online for prices for new flat screens (above 50") and then compared that to the estimated cost to fix my tv's unknown problem. I thought, if I'm gonna have to pay $200.00 or up to fix it, I might as well get a new "larger" one instead.
So, if all goes well, when my caps arrive, I will replace the 3 capXon LZ's and my tv will be rocking again for under $20.00......woo-hoo

Re: Philips 42PFL5432D/37

I already called and checked availability and had him set them aside for me.

Check the part numbers carefully before purchasing. Radio Shack sells more than one iron and solder.

Re: Philips 42PFL5432D/37

It just kills me to think of all the electronics that we have thrown out over the years with the same problems.

Part of the reason for the above I think are:

1) Electronics gets cheaper and cheaper every year making repairing a less economically viable option.

2) People are brainwashed into thinking newer is better (see iphone/ipad/ipod generation).

3) Some, not all, TV "repair" shops simply swap entire boards and don't even do component level repair. For that, they buy an OEM board which costs $$$ and charge you $100/hour for the service. Quite often, I have seen people here say that the repair costs exceeds the price of a new TV.

4) Some electronics are impossible to DIY repair. Try soldering in a 200 pin IC at home. Try working on cell phone boards where you need 30x magnification just to see the component.

Re: Philips 42PFL5432D/37

I already called and checked availability and had him set them aside for me. They are open till 9:00 so I am thinking about going over there this evening.
