    Does this look like burn in?

    Got this a week ago. Just finally got to it. It's a Toshiba 42HP66. I had a good logic board so I tried that first. I think it might have been worse before, but I can't really say. This uses the same PDP as the Viore PDP42V18HA I parted out last month because it wasn't worth buying a main for, and also because it had slight burn in. I'd left it connected to my laptop with no screensaver for a couple days, lesson learned. So I actually have another PDP to try, but it's not much better. And it's a whole lot of work just to see if it's burn in before I part it out. Vs and Vs are dead on too.

    It's the whole darker area in the middle that I'm talking about.

      A few days is unlikely to burn in the screen, but it might cause image retention, which needs time to fade.

        This one, I have no clue how long it's been down. I guess I'll try the other PDP later. That one's been sitting for at least a month.

          think I read about some tvs having a setting or procedure, something about white screen that helps clear up screen retention?

            Run it for a day or two with static from atsc tuner. Worth a shot to see if it normalizes.

              I think he means NTSC static.

              I agree, though, it's probably not really burn-in of the phosphors, a good wipe run or snow static for a couple days would likely clear them right up.

              I've seen several plasma panels that I thought for sure were starting to burn in (from computer outputs left on too long / media center selection screens, etc.) that faded out just fine after some time on random noise but it takes a lot longer than the typical built-in 20 minute or so scrolling-white wipe cycle in most plasmas.

              You'll probably have to feed in a video signal of static from an external source or disable any auto-shutdown as most tuners will recognise no/low signal and shut off the TV for inactivity.

                I meant atsc, just static from a dead ota hd channel.

                  that was it, white wipe, havent come across only a couple plasmas, they look very challenging.

                    HANNSG Hi221 -- 2 secs to black feat. CCFL flicker & "burn" marks on power board
                    by ttmi100x
                    Greetings everyone,


                    I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...


                    The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
                    Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.

                    Upon closer inspection...

                    Insignia NS-43D420NA20 backlight on no display - LCD panel burn failure
                    by howardc64
                    Eventually discovered a burn mark near lower corner of LCD. Here is a summary
                    • Backlight on, no image
                    • Disconnect right buffer board (view from front), left side display comes on
                    • Masked off pin 7+8 (both ~12,5v on both left and right buffer board) from t-con to right buffer board (view from front) display works but have some lines
                    • Buffer board is pretty simple
                    Removed the front bezel to examine edge of the glass. Found burn mark on lower right (view from front). Plastic bezel covering the burn mark region shows heat signature on the inside surface facing the LCD panel. Last 2 pics. Bright...

                    Westinghouse TV WD48FAB100 Not Powering On – Burn Mark Found on Power Supply
                    by Seville
                    Hello all!

                    Westinghouse TV WD48FAB100 Not Powering On – Burn Mark Found on Power Supply .

                    I have a Westinghouse LED TV, model WD48FAB100 that is not powering on. Upon removing the back cover, I noticed a burn mark where the AC cord connects to the power supply/main board. In this model, there is only one board combining the two functions. Previous owner said the TV experienced a lightening strike, but who knows. I checked the main fuse, tested OK. Here are a collection of readings from the power supply ports. Looking for some guidance on what to test/check next....

                    Sony VA panel burn in
                    by dumbdd
                    I have a Sony 75x940e that I just fixed with the help of the forum (bad emmc). For the last couple of months I was noticing some burn in of the android home icons on dark backgrounds (photo is attached). I always thought VA panels were immune to burn ins. Is there anything I can do to fix it? Could it be because of a failing component other than the panel itself?...

                    Help with Dell Latitude E5470 that shuts down when moved at all. Powers up, but no charge, power jack has brown burn marks
                    by lowpost99@gmail.com
                    I have a Dell E5470 that powers up and boots windows no problem. Using a non-standard universal type charger, it shuts down immediately if moved, (power short in that charger or AC power jack) because the battery has no charge and isn't charging orange/white lights blinking on the front. When first powered up, BIOS power alarm stated that it could not detect the voltage setting and I had to dis-able the message to get past this. It got into Windows fine, as long as not moved, so I dis-assembled it looking for a cold solder joint on the power jack that I thought might be lifting off the MB, but...
