Panasonic plasma TH-42pz700 has left hand side of screen distorted

Sometimes when turning on the screen the left hand side (full half screen) picture is distorted showing a multi colored picture. The right hand side is perfect. Can anyone help?

    Thanks SD Tech. Does this mean there is a dodgy connection to the left board or even that the board needs relacing? The problem doesn't happen all the time and is often rectified by turning the set on and off a number of times.

The set uses two boards to drive the screen --one for each half or side.

Different names are used like sustain or in LCD sets inverter.

    you can wait if you want for it to get worse or fail but on occasion when it fails this can damage another board or parts currently good.

Just taken mine in for repair and was told this. "After checks to Switching and Data flow to PDP, Suspect the Plasma display panel to be at fault
which also may well have caused damage to the buffer and logic boards."
I am presently trying to get currys to replace it as it 18 months old.
Forgot to say was quoted £1200 to fix!!!!

most likely this is your y or x sustain boards and if that does not fix it . it could your pdp panel cost varise on part . The cost of your pdp panel is very expesive this th has lots of problems. I would call your local tv shop and have them give you a estimate.First ask thme how much they charge for a estimate. good luck.



Thanks doctor video

SOURCE: intermittent 3 inch green vertical line-5 inches from right side

it you have a repair skills you need to open the TV and make sure all the ribon connectors around the circuit boards are proper connected
and if all seems to be ok, the DG board will need to be replaced.

If you dont have any repair skills I would recommend you to take you TV to a repair shop since this is complex repair

SOURCE: Panasonic TH-42PX60U PLasma - 1/2 screen blacked out

If the screen split is exactly 50/50 top/bottom You are not getting SU or Scan Upper drive.
These are lovely set to work on.
Most likely is SU board itself - Not repairable just to be replaced.
Sorry I work in the UK so I can only guide that the UK part is around £30
SU may have been damaged by failure if the PDP (Plasma Display Panel) but is 9 years only had 2 screens damage the SU board.
There are several setups to do after fitting a PDP. If you don't have the service data - Do not risk it, Reduced life of the Panel and a safety risk.

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.

How do we get the picture back full screen when it will not show the menu because it is only showing the lower half of the screen for some reason

HELLO.
Sounds like one of the buffer boards has gone.
BEFORE YOU TAKE MY ADVICE PLEASE BE AWARE VERY HIGH VOLTAGE INSIDE, IN SOME SETS 2,000 VOLTS DC.
you will need to turn set off for 2 hours before any work is carried out.
as you look at the back on the bottom are 2 or 3 sets of long thin boards, one of them is gone.
either change one at a time or the whole lot.
hope this helps.

Panasonic TH-50PX70EA HAS A HALF SCREEN PERFECT BUT OTHER HALF IS LINED AND CHANGES COLOUR AND SOMETIMES GOES BLACK GETS CLOSE TO PERFECT THEN GOES LINED AGAIN PS sorry for caps

If its a Plasma it uses sustain or t con boards--sustain will usually be two--one for left side and one for right.

Only boards are sold for these sets--no individual parts--discover which board drives the right side and replace it while crossing your fingers--either it fixed the problem or you have a bad display panel (entire screen unit which is fatal from a cost point of view).

Iwas watching my panasonic plasma and the screen went green.

One of the "Y" buffer boards have failed. The buffer boards are located on the left side of the set looking from the back. There are two of them. One for the upper half of the screen, one for the lower. Disconnect and replace the one that had the blank portion of the screen.

White dashes across top left of TV screen

That is what I was going yo suggest. You can also adjust the picture size. "Just" will show all of the picture even the distortions on the edges. "Full" will in effect overscan and trim those edges off.

Picture problem, half screen blank

On a plasma there are 2 buffer boards, upper and lower, it all depends which half of the screen is on as to which buffer to replace, the buffer boards are located usually on the left hand side if you have the back off the unit. You maybe able to reseat the ribbon cables and get the video back up
