Have a friend who brought me a lg 50PQ10-UB he explained there was an issue with its power button *which i could see why. it sucks* but they said after the tv got put together again after fixing the power button something *popped* and although the tv is working in the menus it is very staticy? with lots of weird pink dots. and when i plugged my snes to it to test how the video works. It's got a huge burn-in issue. Nothing like i've ever seen in a plasma before. there's letters staying on the screen for long periods of time. This is something new i've never seen and would like some opinions. I don't have time to take pictures atm but i will tommorow.. Let me know what yall think. Thanks

Re: 50PQ10-UB Weird burn-in issue
I would check -Vy and Vscan supplies. If you have a scope, check the ramp up/down waveforms are good. Also check the Vs and Va.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

I agree.Comment

Re: 50PQ10-UB Weird burn-in issue
Sadly don't have a scope to check that and yeah there multiple spots that become sluggish I've seen spits in the top left and right tooComment

Re: 50PQ10-UB Weird burn-in issue
With the menus being normal I would suggest main or control board. Run the test patterns via control board jumper and see what you get.Comment

Re: 50PQ10-UB Weird burn-in issue
Ok small update.. check the voltages all the 15v are around 17.3-4 the 5v are near 4.8 and the 193v are near 193v ... the logic board is blinking like a long blink then a short blink.. or __ . _ if that says anything i looked at the service manual and it sucks really. nothing good in it. thanks for the help so farComment

Re: 50PQ10-UB Weird burn-in issue
You will also need to check Vsc and -Vy which can be done without an oscilloscope. These points are marked on the Y-sustain board.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: 50PQ10-UB Weird burn-in issue
Ok saw only a spot labeled like this -<--vy-->+ with a resistor in the middle hopefully this was the point i was suppose to test. for vy 189.5 and for the resistor spot for vsc 135.2v *also check where the y-sus connects to the buffer board for vsc. at that spot said 39.5v for vscComment

This one's a weird one, and still unsolved despite it having gone back to Dell once.
Specs
i7-8750H, GTX 1060 Max Q, 500GB SSD & Seagate 7mm 1TB HDD. 17.3 IPS screen. This has the fingerprint reader in the power button.
Backstory
I bought this from eBay, from a wallpapering shop. £650 in 2020 which was a good price considering it's a gaming laptop. Physically it's in perfect shape, apart from the hinge mounts on the palmrest failing in the time I've had it (I have a new palmrest for it). The usual thin plastic crap modern build quality!...10-23-2023, 04:09 PM -
So, I have a really bizarre issue that I'm struggling to identify the cause of. Working on an 820-02020 board with some bizarre keyboard/input-source character mapping. My suspicion is a possible damaged SPI ROM (U1970), perhaps, but I'm really not sure in this case:
1. The issue is pretty weird, but when installing MacOS, I noticed my WiFi password did not work. I quickly realized the special characters (!@#$%^& etc) were not mapping correctly.
2. I noticed the keyboard layout/input-source is defaulting to JAPANESE every single time I restore the board. I am not... -
