    I took it to the Panasonic repairman during its warranty period and they told me they couldnt get the part, that this was a dual voltage television and the parts arent available for it. The phone rep the serviceman was talking too even claimed the part doesnt exist in their (Panasonic's) system. This television was under warranty when all this happened and as of now I still have a broke Panasonic television that cant be repaired by Panasonic. All I have is the part number of the circuit board that comes from the Panasonic repairman yet doesnt exist according to Panasonic.

It will be best to contact the authorized service center for Panasonic at your town. Some critical parts to Plasma displays will be very difficult to get by open electronic spare part market.

SOURCE: Panasonic Plasma problem

I have the same problem on my Panasonic PT-50DL54 DLP!

I just received my television back from repairs and hopefully, with fingers crossed, the problem is solved. The Panasonic repairman replaced (5) faulty power capacitors. I do not know exactly what that meant, however, he stated that is what was causing the set to shut off, triggering the various blink codes. Anyway, good luck... I think we all are experiencing the same problems due to a faulty design flaw. Let's hope this works...

SOURCE: Panasonic TH-50PX750 only has picture on bottom

This could be the screen itself, or it can be the driver board. You will have to bring the set to the authorized service rep. They will swap out boards to determine where the fault is.
If the set is out of warranty it may be fairly expensive to service.

SOURCE: Just yesterday, my Panasonic TH-50PX75U HDTV

There are several possibilities here. Four different boards are involved in the horizontal scan of a plasma tv. The most likely order of failure for what you describe is; SC board, Su and SD, and finally the SS. These are Panasonic's names for what are more commonly known as the Y Main (or Y-Sus), the upper and lower Y buffer boards, and the Z main (or Z-Sus). Sorry I can't boil it down any further for you,... would have to measure voltages, etc.

SOURCE: PANASONIC TH-42PX60U 42 - half of screen not working

I had the same issue. I am going to replace my scan buffer boards. The upper half of mine works but the lower half is black so I would replace the lower Scan buffer board but in case of future issues I have ordered both upper and lower for $44.
The scan buffer boards are fairly simple to locate. Open up back of tv there are two biffer boards identical. The item or product code on them contain letters either SU or SD (Scan up and Scan down)Look up tv parts and item code you will find a place to order or just get the 1 800 number from tv manufacturer.

Panasonic TC-P42S2 .. Transparent 2 inch wide vertical discoloration on panasonic 42 inch plasma, very left of the screen.


Fixed mine, myself! Black 3 inch vertical band (stripe) appeared after a cros country move on our PC-T50G10. Occasionally we would see white band with multicolored pixel width stripes. Took the risk of taking off the back to see if I could see anything. Found places on sides and bottoms where plastic like 2" flat cables could be seen. Guesstimated where the band was and found that I could flip down a black cover on one end of the cable. Tried to pull it, gently. Mistake. Realized it wouldn't one out like computer hard drive cables, so I took out the screws holding the plate on the other end (it's only an inch long). That allowed me remove the cable. Took it out, cleared away dust, put t back and closed the black over. It worked! Put the screws back in, back on and... we are happy (although I do have four extra screws!). Just be gentle.

Right half of screen black with thin blue line top to bottom about another line inch over another thin line starting blue then red getting thiner to bottom


This is a very common problem with this Panasonic set where half the right side is bad and the other half is good. This has been traced to a general plasma panel defect in the manufacturing precess. The panel lasts only about 1.5 years and they go bad. The only solution is to replace the plasma panel. The charges for the cost and labor will double the original prize of the TV set.Good luck.
