With older TVs it can be just a crappy LCD panel with poor motion response.
Also turn off any and all noise reduction systems - they apply a lowpass filter to the image increasing blur in most cases I have no idea why anyone would want to watch that.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly ‘new' Tcon board this time, and... -

This time the original cable broke too close to the screen, it can't be fixed without tearing the screen... -
Have a Samsung UN50NU7400 which shows a boot screen and a screen saver if left on long enough but no picture ?
Would a moving screen saver confirm that the panel is ok or it could still be a panel issue ? -
Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".
It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...07-31-2025, 08:37 PM -
Hello, I need your help for a failure on a laptop:
It's a Packard Bell Kayf0, motherboard LA-5021P, Rev 1.0 with graphic issue.
I received this pc because it was turning on but not displaying anything, the fans are running normally and all chipsets heat up on startup but no picture on screen, no backlight either. I noticed that ENAVDD and ENVDD are not present and that there is no LCDVDD on the connector. I didn't check the screen because, maybe I'm wrong, but if there aren't these signals, even if the screen is good, it can't display anything? I tried heating the...
