Hardware Switch screen darkened (auto brightness off) and showing "phanthoms" (shadows?)

mendezagus · Mar 24, 2019

And i mean phantoms like if i go to the setting screen i see the shadow of the home page on the back grayed. it works flawlessly on docked mode. Do you think it´s the screen busted? i barely used it in handheld mode (no more than 20 hours, i didn´t even took it out of my home) and i read in this thread:

Does it persist in-game? Is it only after-images of the top menu?

Persist in games, it´s always like that (in handheld mode)

Yes, the scanlines. When i finish playing a game and return to the home screen you can see the screen of the game i was playing like a ghost in the back.

I´ll check the connection, i´ll have to get a small enough screwdriver

The screen controller might be failing, or there could be a bad connection. Issues like this aren't common on IPS screens, as they don't suffer from burn in, so it shouldn't happen unless there is a hardware issue.

I had an issue like this when I didn’t reset the screen ribbon cable into the connector fully, I would try that first and make sure the latch is fully in place and the tabs on the edges are against the connector. also if it’s only in handheld it’s at least not totally a brick XD

Thanks everyone! So you don´t think the screen is busted?. I´ll risk open the switch if there´s a simple problem like a conection failing. If the creen needs to be replacede i´ll rather send it to a shop.

I bought a GameStop premium refurbished that had the issue I had, but had screen flickering and partial and total blackouts on the lcd I could press on the back of the console where the connector is and it would get worse or better. I would try that first

Well, the faulty connection could be inside the LCD itself. Not much you can do if that's the case.

Ok people, i´ll see what i can do. Thanks for the replies, will report later when i fix the switch (i´m decided to take it to the shop)

If it’s covered take it shop and get swapped... If it’s not open, top left corner and above/side of fan are where the lcd clip is, turn switch on push it lightly, see if it makes any difference. If not check all your paste is not dry as that could of made hardware overheat and that would then be the issue. A reflow of board may fix it if hardware issues.
