    purchased the manual - thank you!

    Just wanted to clarify - of the boards listed I see only 1 Scan drive, then a Scan Out Upper and a Scan Out Lower; and also a Data Drive Lower Right and a Data Drive Lower Left. Which
    one (s) would we be looking to taking a shot at replacing? Sorry - just bugging you again because
    of the single Scan Drive board that I see listed - and we were going to do as you suggested and try
    replacing the 2 boards, going with the assumption that the other side would be going out too!

    thanks again,
    susan

The first thing needed is a Service Manual. This will help you take the TV apart and remove circuit boards properly without damaging anything. This Service Manual will give you factory part numbers for replacement circuit boards plus other helpful information about the TV. Here's where you can get one:
http://www.service-docs.com/store/catalogue.php?cat=278&exp=&resultpage=36&shop=1
You can shop around the net for cheaper or maybe free one. But, free Service Manuals are rare.

When you take the TV apart, I'm 90% sure the bottom left side buffer board needs to be replaced. Sometimes called a Scan Drive Board or Buffer Board. The Boards on the bottom control the vertical image and the Boards on the side control the horizontal image. The right board controls the right side and the left board controls the left side ( Well, you get the idea ). It maybe a good idea to have both bottom boards replaced. One board goes bad and the other board is probably not to far along to go bad.
Good places to find replacement boards ( at a non rip-off price ) are at Shopjimmy.com or E-bay. Just make sure the part numbers match up on the board itself or the Service Manual.

    Don't worry, your not bugging. :)


    I believe it would be the Data Drive Lower Right and a Data Drive Lower Left. When the board burns out, it would have a bad smell to it and it would over heat. Look for dark burn spots. It may not show any signs, but it should be the Data Drive Lower Left causing the problem since the left side of the screen isn't working. The Data Drive Lower Right may go soon since it's the same age ( just a precaution ).

    I'm glad your TV is fixed. Have a happy Valentine's Day. :)

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.

Plasma TV with vertical lines


Help! My Plasma by Magnavox is putting black verticle lines on the right side of the screen - comes and goes - and I replaced the entire Direct TV-HD unit - wires, everything - and had TV company repair - and it still came back. The TV repair refuses to take TV back because it does not show up when they come. Although I videotaped it and showed them which has the date and time - they still refused to take it - and tried to get me to sign a paper saying it was working while they were there - which of course I refused to sign - so they left and nastily said they will not be back-find someone else. I still have the lines - and do not know what to do! Can anyone help?
