50" Philips 50PFP5332D/37 no picture, has sound

[SCCAMPER]

My Phillips 50" plasma tv lost picture but has sound. Tv was on but not being watched when it quit. Dont know if it made any noise or such. We had no luck leaving tv unplugged for 24 hours. Blue power light comes on steady. Ive looked at all the caps, tested the fuses, and looked for burnt spots on boards. With power turned on, several green led's lite steady and 1 flashing green led. I can hear relays click on at tv center and can hear a buzz from a board on screen right(right side if looking at screen, left side if looking from back). Can anyone give me an idea of where the problem could be so I can scrutinize and further check closer. If I need to provide any further info let me know, thanks.

Please post pictures of the boards inside the TV under "Manage Attachments". People won't respond if you don't attach photo's as a reference

Pic 1&3 are rotated(sorry), each are boards on side of tv. I can hear noises from boards in pic 1&2. Some of the small boards are behind chassis brackets and hard to get to, if I need to tear apart I will.

Those pictures are really too small to examine anything. Can you get bigger ones in good light?

As it stands, in the second pic it looks like you have bulging caps, remember they only have to be slightly bulged before failure. There looks to be one next to the middle heatsink, and *possibly* ones near the left hand heatsink, they are very small and hard to see.

get beter pics tonight. thanks

The best I can do at this time is take photos closer to caps, only have a phone camera. Ive looked closer at the cap in center of heatsink and it does look like it has a small buldge, the others in question Im still not sure about.

Here is one that looks different but no others to compare.

The one with a black top - is that bulging at all? Can you press in the top?

I'd say replace all the suspect caps, and see if that fixes the problem. If not, we need to look deeper.

In no particular order, place the following items on your 'to do' list.

1. Replace the bulging cap under the heat sink. It almost certainly is not the cause of the problem, but it should be replaced.

2. Ignore the cap with the plastic top. Those disks always bulge.

3. There are cables running from the power supply to the Y-Sustain (left side) and X-sustain (right side). The voltages on those cables are noted on the power supply. Some of them, such as Va, Vscan, etc. are listed on a white label on the back of the panel itself.

4. Check the fuses on the sustains.

5. Decent 4 megapixel cameras are available used on eBay for under $15, including shipping. Buy one.

6. The service manual is available at Elektrotanya.

7. Philips has a service manual covering troubleshooting the plasma panels in the TVs they sell. To locate that it is necessary to know the model number of the plasma panel in the TV. That information is also on a label on the plasma panel.

Thanks for all the help. I will work on my to do list and update when I have some new information. The site has a wealth of information and Im still taking it all in. Thanks again.

so was there ever a solution to this problem? I'm having the same issue. The black cap seems like it is slightly buldging also. How can I replace this? Seems straight forward, although, I haven't done anything like this since high school.

The big black cap has a slightly domed top even new. Post some photos of oyour boards. Are you getting the same no picture but has sound?

Were you able to resolve this issue of not getting picture? I am having similar issue.

When you say no pic, are you getting backlight?

Hello I am new to this site, I recently got a 50 PFP5332D/37 tv. I turned it on and I have a very dark screen, almost No color to it at all, I do have sound. I tried plugging in my dvd player and that does play and I have audio but again the picture is almost all very dark. When I try to select the menu button my screen pixels seem very slow to operate, the screen seemed to slowly fill in in various spots but eventually did fill in. The blue light is on in the front and I did notice 1 green light on in the back, not sure if there should be more on or not? Any ideas of what to check first would be great!! Thanks so much

For a little more information I did remove the back of my set and check all my fuses with a fluke meter set on ohm's to sound when resistnace is good, every fuse beeped telling me that they are all ok. I did notice that when the set is on there is a Led blinking. the location is on the lower left board and the Led# is 2002. On the same board there are 2 other Led's and there numbers are 2000 and 2003 and they stay on solid! All the other Led's on the set stay on solid, so I am wondering is there a fault here and thats why it's blinking if so how do I figure out the root problem?

Re: 50" Philips 50PFP5332D/37 no picture, has sound

The green light blinking and the other 2 staying solid is normal. Thats what it does on my set. I think its blinking because it's getting a signal. Is the dark picture complete or does it have a lava lamp apperance?

When using continuity beep mode on any multimeter to test a fuse, the results are unreliable.

Most Flukes will beep "continuous" for resistance readings less than 30 ohms.

A good fuse should measure less than 1.0 ohms.

I have a fuse that beeps on my Fluke. Is it good? Nope, it reads 18 ohms.

Some cheaper multimeters will beep continuous for readings less than 1800 ohms.

If you've got a dark, very poorly lit screen, it's almost always the X-main/Z-sustain board (Samsung/LG terminology.)

Guys, I have an issue with this same model. Can anyone tell me what may be the cause by the attached image? Power comes on, display lights up, but picture is "bleeding"??? Is this a capacitor issue?
