SOURCE: hitachi P50H401 no power but when i replace sdr-u board

I just solved this problem on my TV. I replaced my SDR board and had the same lines. I reseated all of the connections, and gently pushed them in until I felt a slight pop. once I felt that I gently pulled on them to make sure they would stay in place. if they did I closed the locking lever if not, I repeated this action. then simply turned the TV on and all of the lines were gone.

SOURCE: My Hitachi p50s601 recently went dead and was send

the streeks are from the cables not being installed right. the cables that plug into the sdr board. if they are not seated right you get lines in your video. going side to side. some times it takes many tries until you get them in right. you can kind of guess what ones are not in right from were the lines are for the connecting cable to the screen. what i do is i do one at a time and see if the video gets better or worse and power it back on and off and work my way down until the video is normal.

Black horizontal lines on screen on my p50h401a plasma tv after replacing upper buffer board

Hello, the problem is with the buffer board ribbon cable. You have to really force them in there till you see no more lines, then close the latches in place "try using both hands" and press into the board HARD :)

HI,i was whacthing the tv and on top the screen did appear 6-8 horizontal lines,i did try to turn on/off,......i need help.thankyou.

Normally this is an overheating issue or a power supply issue. For the overheating issue, take a vacuum and some compressed air and blow out the back of the TV. Dust can collect and cause components to retain heat that will cause the TV to produce horizontal lines called artifacts. Sometimes these are permanent but sometimes they can be repaired before replacement.

The top half of tv has lots of horizontal lines going across bottom half ok

Was it dropped?
It sounds like panel has been damaged. There is an array of very fine connections on the top or bottom and the left or right (one each) and if you break the connecitons it looks like you describe.
Does it look like this? ?

JVC PD-42DX6BJ plasma 42 inch black horizontal lines over the pic

Here's a link to order the original the JVC upper Y-buffer board and lower Y-buffer board for this model from a major parts distributor if needed:

JVC "PD-42DX6" Replacement Part Upper Y - Buffer Board (LJ41-02760A)

JVC "PD-42DX6" Replacement Part Lower Y - Buffer Board (LJ41-02761A)

Based on the symptoms: It is possible that the Y-buffers are faulty, which may require the replacement of the Y-sus board as well. You may want to get a local technician to diagnose the unit and provide a second opinion.

Mitsubishi WD-62628 Projection TV Failure

The DM board is the one with the digital connectors on the back panel. If you already have it appart, you may as well check the caps on all of the boards. The caps that go bad are typically Jamicon brand caps in 1000 uF and 330 uF values. There are also a couple of 3300 uF caps in the PS that cause problems.

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
