    This is a wild guess, probably someone else can tell if im right or not, but i would guess its moisture or similar that have made the top layer of the panel get loose in the corners.

          Re: need inputs

          I've heard of a situation where light from the back-light 'leaks' around the edges due to ill fitting parts but I've never personally seen the problem so I dunno if it looks like that.

          The solution to that is to adjust the parts and/or use electric or metal tape to block the light leakage.

              Re: need inputs

              Which model Dell is that?

              I've heard of the backlight leak problem and saw a site that showed a step by step fix. They used electrical tape to seal the edges of the panel. But that was a while ago. BRB...

              Going by the picture there and comparing it to yours, I don't think you have the backlight problem. His looks like a fading effect. Yours looks like someone scraped the pixels off. Looks more like the panel edge bond has failed and the layers are separating.

              Hopefully someone has seen this before.

                    I think only number 1 is applied here since I used different video cards. caps are all checked using multitester, esr, and cap meter.

                            I think maybe some kind of delamination problem.

                                Hello Everyone.
                                This powerful amplified subwoofer doesn't make any sound after lightning striked near the house were it was plugged in.
                                It consists in :
                                • a power board were the full H bridge class D amplifier and main power rails are located
                                • a preamp board (ref. F.01U.299.771) receiving 2 symetrical inputs(IN1, IN2), a digital chain (A-D converter -> Digital Signal Processor -> D-A converter) and a micro controler in charge (at least) of the human interface (lcd display and 1 rotating button)
                                Power rails are ok.
                                human interface is working fine

                                Hi All,

                                Thanks for reading. Based on the interesting fact that the vertical lines issue don't seem to effect the menus whatsoever but rather everything around the menu regardless of video is shown, I'm trying to set mine whether the issue is the main board or the t-con board.

                                Again what's baffling is that the menu is not effected whatsoever. However, any other video displayed regardless of inputs or when no inputs exist exhibits the vertical lines and seem to effect black areas only.

                                The lines are green in color when the tv is in "Game Mode" and...

                                by karthur
                                On this Vizio D65x, the volume will change on its own. I don't mean like during commercials where the volume will increase. I mean its like the (+) volume button on the remote is pressed and the actual volume dialog is displayed on the screen going up. It will do this, then the volume may start going down. It might go all the way to "0"or it might stop at a different number, then start going back up. The whole time its doing this, the volume dialog is shown on the screen.

                                It wont do it until it has been "ON" for 20 or 30 minutes, so it does seem to be heat related....
