Re: Samsung PS42A450P2 plasma screen problem
Wife got tired of being without TV, so I bought a new Vizio LED LCD TV today. Have not given up on Mr. Samsung Plasma though...
I found a Main Board for sale that comes from a Samsung PN42A450P1D (a North American model): http://goo.gl/O3i3J
Will be about USD 75 including shipping.
Based on other items for sale on Ebay it looks like the North American TVs use the same Logic Board (model LJ41-05078A) as the European TVs.
So...I am guessing that the North American board above is "close enough" to my European model PS42A450P2 that it can communicate with my Logic Board, even though the TV model suffixes are a little different.
Does that seem reasonable so far?
OK..other differences:
1) The connectors (LVDMS, Power, Speaker and IR) are in different locations on the Main Boards. I guess that will take some hacking. May be tricky trying to extend the LVDMS cable.
2) The North American board is a little shorter than my European one. But actually, my board is mounted to the TV frame using the set of screw holes 2nd from the top, so should not be a problem. Board widths are the same.
3) I probably have to cut some holes in the TV case since the signal input connectors are different. (No SCART jacks. More component-in jacks.) Will be a real Frankestein job, but it's the back of the TV, so I don't care.
What do you think? Worth a try? Looking for some words of encouragement or calls for sanity.

Re: Samsung PS42A450P2 plasma screen problem
Just want to put some closure to this thread that I created back in September. I decided not to pursue replacing the main board on the Samsung and am going to see if I can part out some of the remaining functional components.
A big "thank you" to everybody on the forum for your help. It was fun doing the diagnosis even though the patient didn't get saved.Comment

I have a Dick Smith 37" LCD TV, Model GE6804. I am using it as PC extended monitor only.
Problem is while watching tv, I hear a semi loud click(like a electrical breaker tripping due to overload, just sound like it but no actual electrical overload), then screen is covered with green or pink. I can still see the original picture image but overlayed by green or pink. See attached images. Pink.jpg is what I see, and Normal.jpg is before green or pink screen, What I captured was pink screen, but about 80% of time it's green and 20% of time it's pink.
Then each time... -
hello,
I hope someone on this forum can assist me.
I have a panasonic TH-42PC77U plasma television.
the lower 1/2 of the screen has become flaky....in and out, then finally goes black and you can only see the top portion.
i have performed the reset to default settings quite a few times. Panasonic recommended..did not believe this would help...it didn't.
I have removed the back panel and looked around for something obvious...burn marks in a board, etc....nothing obvious...
I have read some posts that suggest the problem is related to the boards on the left... -
This curved LCD TV has an issue affecting just the right side of the screen. It is not a backlight issue, although it might appear so from one of the attached images. The problem appears to be the right side of the screen not updating properly. Moving images on the very right side will leave a trail of ghost images. Although even just the computer cursor sitting still makes a vertical ghost band the entire height of the image. The color on the right side also looks like it doesn't have the full bit depth (the Windows background looked kind of dithered on that side).
I went into... -

My Panasonic Plasma model P55VT50 has started displaying "interference" on just the left half of the screen only (left when facing the screen). Sometimes it's concentrated in about the first 30 seconds after startup, then disappears. Other times it's fine at startup and then randomly does it later on. When it flashes the interference it's very quick and doesn't stay on the screen unless it flashes repeatedly in a row.
This image is a screen shot from a video I took. This is an example of the interference at its worst. Often the interference is much smaller...10-14-2022, 04:54 PM
