Philip Plasma 50pfp5332D/37 Single Horizontal Colored Line

[Round2thrift]

I have this 50 inch philips plasma TV has a great pictures when i first turn the set on i get two colored lines at top of TV. when i switch it off and back on i only get one line in the center of the set. there is also a sparkling on the y sustain side of the TV. I had to change the upper and lower buffer board. This line is very thin and seem as if it is on top of the image

Any help would be greatly appreciated

Advise do some research on google plus the forum. Read what you should add to a thread. Run the test patterns. Test voltages. Help us help you.

Watch this, helps if you did some research for yourself on this chassis, Ysus failure kills buffer you need to test the Ysus for short circuits:

Ok so thats with the Ysus changed you now have image ? I advise you reseat the buffer connections going to the screen. If it still persists then check the buffer Ics in that area see if one has a shorted line. Panel failure like this is very very rare.

yes i now have image, i have clean and reseated the buffer Ribbon , the x-main , the logic board and the ribbon to the address board you mention test pattern i have not tried or know what that is

I found a post from tom66 on how to run the test pattern by jumpering the 3 and 4 pin on the logic board. Test worked fine still showed the horizontal line threw all colors but green

any suggestion? anyone?

The line was in the exact centre of the image in first pic (Like Frame-Collapse on a CRT!)

Second picture its displaced much closer to the top....

Check buffer connections--those plug sockets can be trouble if ham-fisted repairs been done...

Fact that the line has moved proved panel is OK, and prob Buffers OK too. YSUS is working so is XSUS. Possible the cont board is messing round....

You are right alastair the black screen shot with the line across is without any input connect the second is with DVD playing i have reseated and cleaned the ribbon as advised by reecey on buffer, still got the line what is hand fist repair? that has not been done by me anyway and is there a way to test the control board?

Re: Philip Plasma 50pfp5332D/37 Single Horizontal Colored Line

Ham-Fisted = Rough Treatment careless and forcing things...

Cont-board by substitution as you have already run test-patterns.

The Position Of The Line Isnt Constant--Therefore implies poor connections from panel to buffers.
--Each Line is addressed by its own part of each buffer chip.

Only things that could make a line change position are fiddling with buffer/panel connections or the cont-board messing round...

Re: Philip Plasma 50pfp5332D/37 Single Horizontal Colored Line

No i have not ham-fisted it lol but i did change out the control board can this be bad even after the successful Pattern test? if that the case i got a bad board the original was toasted

Re: Philip Plasma 50pfp5332D/37 Single Horizontal Colored Line

Got My used Control board today installed it and what do you know, No More Lines that fixed that problem. thanks Alastair E and Reeceybuger123 you guys were spot on. I still don't have a crisp picture seems a little out of focus do not have the original remote even adjusting the contract does not help any suggestion will help

Thanks

Good work enjoy the Tv also I suggest you fan cool that Ymain and recap the 3 680uf caps on it and the Xmain too as well as heat-sinking the buffers keep the fucker going

Re: Philip Plasma 50pfp5332D/37 Single Horizontal Colored Line

[ReeceyBurger123]

Re: Philip Plasma 50pfp5332D/37 Single Horizontal Colored Line
