Pleased with myself. Fixed my monitor

Yo.

I'm feeling quite pleased with myself.

I have a Philips 43" 4k Monitor, its around 3.5 years old at this stage.

In November, I noticed a bright spot, which was horrible. Then I noticed over the weeks following, more bright spots.
I was devastated (well, as much as can be when your monitor is unwell).

I replaced it with a small 34" MSI 4k curved gaming monitor. But it's not the same. It's too small. .

Last night, I decided to pull the monitor apart, look for anything broken.

I found that 1/3 of the little light domes had fallen off their LEDs. So instead of a diffused light, I was getting focused light, hence bright spots.

I checked every one, and with a gentle poke, they ALL fell off.
Wow... OK... so I grabbed my super glue, and spent an hour glueing each one back into the correct locations.

Then I rebuilt it, and.. Wow, no more spots. Perfect image...!

Very pleased. Now I have it mounted above my 34" on a large pole, I feel like some sorta trader.

Happy days.

So... if your large monitor has bright spots. Check the Lighting system.

Nice job

Sounds like that one was engineered to fail just out of warranty :/

There's probably a lot of truth in that. The only Philips screen I had, which was ace btw, failed after a few years with the OSD controls randomly appearing and phantom button presses changing all the settings (contrast, etc, would go up and down, up and down).

I had to open 'er up and remove the whole PCB with the OSD controls on it. So I could only control the monitor via EDID/DDC, but hey, how often do you really need to fiddle with monitor settings

Looks like you could be right, they used standard hot glue to put the little domes on. As we all know, hot glue melts and looses its stickiness when warm..
After many months of use, they just let go.

I used some Superglue gel on each one, so I very much doubt they will fall off again.

Ive seen a few of these monitors on eBay, sell for peanuts due to the same issue. I may keep an eye out and snap them up
