Question about LG DU-50PX10 50 in. Plasma HDTV

Open Question

I have a DU50PY10 ( 50" LG PLASMA HDTV) and the picture is fuzzy and the cable jacks do not work. I had a TV Technician look at the problem and they stated that the "Y Board" and "inuerter" board are bad. I thought it may be the plasma tube but they said they had to check those 2 boards before they could rule the problem beiong from the plasma tube. My question is: Can you find replacement "y boards" and "inuerter boards" for this TV anymore since production stopped in 2006? thakn you

SOURCE: LG "NO PICTURE" , IF FIX WILL RECUR? ,DID LG FIX DESIGN FLAW 42PC3D

I had same problem - no picture, but sound worked - LG 42PC3d - was two months past warranty, but LG agreed to fix it as a warranty call. Service guy was out within a week to replace the Z SUS(?) board. Works fine now. This must be a typical problem, as LG did fix it, even though the warranty had expired. Good luck.

The problem is the "Y-SUS" board. It is inside the set on the left side with several aluminum heat sinks, under the left side brace bar. You can order this board from Union Electronics at www.ued.com .Search for part number: TNPA3243AB-PA

It lists for about 115$

SOURCE: LG 42 Plasma has a black Fuzzy Screen when 1st turned on

Doesn't sound like a fuse-related symptom but rather the sign of a failing capacitor in the high voltage supply; when weakening, their characteristics can improve slightly with warmth but it is likely going to get worse. I don't know your set so can't say if the HV supply is integrated with the main supply or not.

Your model number is incomplete so you will need to add some characters to get the right part.
This company does offer some warranty on their items which are primarily gathered from disassembled sets but check with them:
Jimmy's Parts
If you replace the failing board, don't throw the other away, it is a repairable item if you find the right technician.

My TV doesn't have picture its fuzzy in different areas not the whole screen and makes with clicking noise when its turning on.


Invariably the HDMI cable that you are using to connect the signal is bent and pressing hard against the wall. Can you verify with other ports and other sources.

Picture is fine for about an hour then goes fuzzy


Hello Townsend, It sounds like a problem called blooming, or you are having a problem with focus control which are signs of a problem in the horizontal and high voltage section of the tv in the case of plasma TV this would be the excitation circuit. I would suggest that you take the set to a TV repair shop to effect repairs.

Just bought the Samsung 550 Plasma Hd Tv can you tell me if we just use a regular cable from the wall to the Tv will the picture quality be sort of off.. WE have an HM MI cable from the cable box to the TV...


unfortunately cable does not give you the best quality picture and "fuzziness ' is the reduced resolution being displayed on the tv.
the easy way to check the picture quality is to get a decent hd antenna and scan using it for free hdtv signals, if these are also fuzzy, on all channels then the tv has a problem but if it is only on a few lower resolution channels then its just the way it is until everyone is hd 720 or better.

LG Plasma Problem


This could be the main drive board failed, or the plasma display backplane has a defect. These types of repairs are generaly fairly expensive.

I would be considering to get an estimate just in case it is simple fault. But, if the repair will cost more than a few hundred dollars, I would strongly suggest a new set. Also, servicing an older set is a gamble in case something else will soon fail.
