Hi


Thanks for using FixYa. From what you have described it seems to be the issue with Y-main however, Y-buffer and the logic board should also be checked. These boards are located on the right side of the unit and to check them you’ll have to open the back of the unit. Once you have opened the back also check for any blown/bulged capacitors.
All this is only recommended if you have electrical expertise & know how to solder/re-solder components as these units contain high voltages even when in off position. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

My 5 years old Plasma TV found half of the screen picture view not very clear.. The half colour seen blur..


Your Buffer boards or the YSUS main are bad. THe YBU-Y Buffer upper controls the top half of display, the YBL-Y Buffer lower controls the bottom half and the YSUS Main controls both those boards. They are located to the Far Left on and opened Set.

Bottom half of the screen flickers and goes black


Hi
I would suspect this to be the lower Y Buffer board, with the back removed of the set it is on the far left hand side( lower ) and coonects via ribbons to the screen, get the part number off the board and Google or Ebay for a replacement.
Hope this helps

Most cases the Y-SUS, Y upper buffer, and Y lower buffer is the problem. The replace the 3 boards are located on the left side of the chassis when you open up the TV. 90% of the time this will solve the problem.
Look for burn marks on the upper and lower buffer boards (mostly around the chips with the heatsinks on them).

Hi Mikshanks,

I had the same problem with my TV. It was a horizontal problem with different shades of color, and black spots. I replaced my Upper & Lower Y-buffer boards. Your Y-sus board should be okay since it still powers on the screen. You should replace the Y-buffers Upper & Lower, and it should work. I hope this helps.

best regards,

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.

Phillips 42 inch Plasma -Screen Issues!!!


intermittent loss of picture on either bottom or top half of screen is specific to y buffer boards located on left side of screen going from top to bottom when looking at back of tv. the y lower buffer would be the board to replace to resolve the loss of bottom half of picture. if the top half also is going out intermittently could tied to upper buffer as well but just a note the y main board to right of these buffers drives those two boards so in some cases could also be part of the problem. if only bottom half is affected i would recommend replacing lower buffer only

42" magnavox plasma tv


I partly agree with imaliszewski the problem is Y buffers (upper & lower). There is 3 parts to the Y board (Y-main, Y-upper, and Y-lower). There was an issue with defective Y-buffers in a memo sent out by the Plasma manufacture. The problem could be that you just got a set of these defective buffers in your panel. Or as Imaliszewski stated a current problem. but if you replace the Y-buffers repace them as a set. If your TV goes out again after changing the buffers. The panel is causing the problem by drawing too much current. That was a Defect I found out why working in a Philips/Magnavox warranty repair facility.

Model 42mf231d/17 42" plasma


If the loss of picture is either on top half or bottom half of screen. there are y buffer boards that go from top to bottom on left side of screen when looking at back that control those sections. when there is loss of half of picture then buffer associated with that area would be at fault and would need to be replaced. when i see a degrading symptom such as loss of picture on top half or bottom half leading to no picture issue normally you would check heat syncs on y sustain board and if not heating up after a few minutes of being turned on would recommend replacing y main and both y upper and lower y buffer boards as they complete a circuit

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
