Do the lines go from left to right - or top to bottom? Next, do you find the lines on the top or bottom or the left or right side respectively ? Examples - See picture
Customer: replied 2 years ago.
The lines go completely across the screen, side to side, and mostly in the middle third or 1/2 of the screen. Some are a single line, others are bunched together with my guess being maybe 50 lines or more now.
I've already bought an LED TV as a replacement but really like the picture and features of this TV, so before I shoot it I'd like to consider fixing it. Thanks!

All on top or bottom half of screen? Or is it on both top/bottom. It sounds like the "middle third" translates to BOTH.

The middle half of the screen.

Well, sounds like the Y buffer is bad...or it could be your panel. Buffers are cheap compared to a panel. Those lines, they didn't all appear at the same time I'm assuming, they just appeared and slowly increased their amount over time? If so, that sounds more like a buffer. Panels generally cause all lines to appear at once. Consider that. If you think it slowly appeared over time, then get the Y buffer. If you have the rear cover removed, look at the Y buffer which is located on the extreme left side of the TV panel. There's a number on a sticker on it. Match it to one of these 2 possible buffers available for you TV model number. We want the right part. -- Y Buffer, not the X buffer at the bottom of that page. If you double click the Y Buffer picture, they highlight the number you want to look at found on the board, ok?

Thanks! I'll give it one last try to save this TV.

There's 2 choices, make sure you match it to your board in your TV. If you double click the picture and follow the directions at that site, you'll find the actual part number on your board highlighted in pink in the picture. You'll have to double click the picture 3 time for that, ok?
