PoteauPets,

OH KNOW!!! Not the news I wanted to hear. I hope you all find a simple solution for this next problem. How frustrating!!! By the time this is over and done with, we will know this TV inside and out huh?

Re: Philips 42PFL5432D/37

This time however, there are a few things different, when I lose the picture.

1. The green light stays on.
2. White lights in the back stay on.
3. Sound stays on.

1) That suggests your main/logic board is working.
2) That suggests the inverters are getting 24V DC (that is new Panasonic 1500uF 35V caps are working).
3) That suggests your main/logic board is working.

New ideas.

1) Let's get an overall shot of the main/logic board so it looks like this (top down view). Tbuch saw 3 bad caps on her main/logic while I spotted 4. Maybe there is another on the main/logic board that you are missing?

We want the picture composition to be like this with resolution as close to 2000x2000 as possible.

2) This is a shot of the same TV by someone else. Circled in red is the t-con card. Take off the metal shielding and post a picture of it with the same picture composition as above.

3) Notice that the t-con card has a connector coming in from the bottom. Reseat this connector. There is a very small possibility that the connector when in the vertical position isn't making 100% contact.

The connector may be fragile so be gentle/careful with it.

4) Notice that the t-con card is the most northern module. When the TV is vertical and mounted on the wall, it is possible that all the heat rises towards this t-con module and it is failing due to heat and no air circulation. With the cover off and the TV in the horizontal position, heat dissipates in a different pattern versus wall mounted/covers on.

THE NIGHTMARE CONTINUES !!!!!!!!
The t.v. played all night last night so I put the cover back on this morning, hung it back on the wall, and within an hour, IT WENT OUT AGAIN !!!
I turned it off and then back on only to get less than an hour, sometimes only a few minutes, before I lose the picture again.
So, when the hubby gets home, he helps me hoist the big stupid heavy thing down off the wall, and lay it flat on the entertainment center. I proceed to take everything off the back once again. I inspect all the caps, new and old, nothing is visibly wrong, polarity is correct, no bloating etc. So, I switch it back on, wait for it to go off again, and it plays for over 3 hrs. What the heck is going on?

This time however, there are a few things different, when I lose the picture.

1. The green light stays on.
2. White lights in the back stay on.
3. Sound stays on.
Any suggestions ????????????? I'm sooo frustrated with this t.v. but am not about to give up. IT'S WAR

Re: Philips 42PFL5432D/37

Hi,

I am still unable to find the part number for the 1000uf 25v capacitor. If anyone could help with this that would be great. Then hopefully the next time you hear from me it will be my success story

The Panasonic EEU-FM1E102 should be suitable. They are available from Digi-Key as their stock number P12379-ND.

Re: Philips 42PFL5432D/37

Another case of "even if it's not bulged, replace it."

Well, it was only a matter of time before those 3 Capxon went bad. We have already seen multiple pictures of that group of 3 bloated.

Re: Philips 42PFL5432D/37

Glad you fixed it! Enjoy your TV.

Another case of "even if it's not bulged, replace it." Especially applicable to cheap capacitors.

I wonder if the caps on the main board started bloating because the main PSU caps had gone bad? And this was putting excessive ripple across these caps, causing them to bulge before the main PSU caps.

Re: Philips 42PFL5432D/37

I am sooooo soooo excited.

Good job. Don't forget to order a new business sign.

Re: Philips 42PFL5432D/37

exception of the one rated 220uf 25v, what do you suggest for this guy?

main();

{

printf(" http://search.digikey.com/us/en/prod...2383-ND/613744 ");

}

Re: Philips 42PFL5432D/37

Hi Guys,
The caps finally made their arrival this afternoon. I removed and replaced all 9 of the CrapXon caps. Put the board back in, powered it on, and it's stayed on for a little over 2 hours now. I am sooooo soooo excited. Remember, I could barely get an hour before it would shut itself off. I think it's fixed !!!! Thank you guys for all your help. I couldn't have done it without you, that's for sure My 10 year old daughter is so excited to be able to watch her morning cartoons again before she starts her school day.
Oh, and one more thing....when I started this whole adventure, I was a little nervous about soldering. I had to replace one cap, then re-do it because I put it in backwards, but after doing all 9 today, I think my solder joints are the prettiest ones on the board......lol
I'm uploading some pics for your perusal. Thanks again guys, WE DID IT !!!!

Re: Philips 42PFL5432D/37

Hi I'm back.... Javascript got boring.

Anyway, I have compiled a list of all the recommended replacement capacitors that I will need to order with the exception of the one rated 220uf 25v, what do you suggest for this guy? ~Thanks!!!

Also, I am having an issue locating the part number

For replacements use Panasonic FR caps (91 cents each) at digikey. Shipping from digikey is about $2.75 USD and you get the parts in 48 hours or so.

Re: Philips 42PFL5432D/37

That is why we always ask for photos of your boards versus referring to stock or other people's photos.

That's a very good idea!! My newbie eyes may not see what yours does

My programming days are long, long, over.

Ahhh, mine are just starting. In fact the TV is on hold for the night so I can work on my schoolwork

Re: Philips 42PFL5432D/37

Yep, that is the one I was referring to, after closer inspection i did notice that it is bloated.

Re: Philips 42PFL5432D/37

Is the 4th the gold colored cap on the opposite side as the three?

Since I can't see the complete board and its relationship, it is the one circled in red. I think it is bloated, but it could also be a lighting trick?

With 3 more obvious bad caps.

I see 4.
