Re: need inputs
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.

Re: need inputs
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)
human interface is working fine
Input levels are...01-23-2024, 10:21 AM -
How do I find my "board path" as shown on openboarddata.org ?
Full model: Mid-2012 Macbook Pro 15" Retina A1398 (EMC 2512) MC975LL/A02-14-2024, 12:30 AM -
the board had some corrosion but on unimportant areas like for the led or diode to Lan port, but I have already removed those corroded components
the vCore VRMonly has 2 of 4 phases firing, at least according to my shitty dso138mini, the 2 phases that aren't firing are indirectly controlled by the isl95712 via
an ISL6625
the PWM pin from the controller to the isl6625s are at 2.4v, ie the idle state
so far I have not found any broken traces or resistors for the vCore circuit
I have flashed both bios chips to latest firmware
I have replaced:... -
Hi all!
A friend asked me to repair his biomass (pellet) heater. This heater has a pellet feeder powered by a relay that's not switching anymore
I measured the voltage at the relay coil socket while entering the individual tests procedures and it has 6-7v while the relay is NOT on the socket, and drops to 0v when the relay is plugged in the socket, like the source is providing nearly 0 mA. I measured the relay coil and it is correct and not shorted so the issue is in the board, fed no amps to this output
I checked the board at home and this output is driven by an... -
Disclaimer Firstly I am by no means expert and this is still a learning experience , I buy broken stuff , with the intention to fix or learn something by failing.. I wanna break this into a few sections, please feel free to mention the section if replying , to assist me on getting a better understanding
Part 1 , identifying Rails .. So for the record , I understand on NVIDIA cards there are several Rails. Along with their Supposed Voltages ( Voltage depends on age/ generation )
Part 2. Blown / Missing component check .. I purchased this from the original...
