Highly irritating monitor problem

almoststew1990 · 9 Jan 2021 at 10:35

I have an Acer Nitro XV272UPbmiiprzx. It's got an annoying problem where the monitor will reset itself (as if it had been completely switched off, and not just lost signal) every 15 seconds or so... but for 5 minutes before it "warms up".

However it' an intermittent problem and yesterday it didn't do it at all! So I am nervous about RMAing it (to a competitor) and it not playing up!

It's not the power cable and as far as I can tell the physical on off switch and standby switch appear to be working fine.

Any ideas about what could be wrong?

Have you tried different cables from the pc to the monitor, checked they're seated properly? Has this happened from when you received the monitor? Or has it just started happening recently?

yes the cables are fine, I've tried all the inputs (HDMI 1 and 2 and DP) and different sources (PC and PS4). It does it with any source and it's as if it is losing power. It only started on Thursday, friday it was fine (used all day for work), this morning it's doing it again.

Take a video of the issue so if its disputed, you can provide that as evidence.

100% this, take a few videos of the issue happening repeatedly, on different inputs, cables, etc. This covers you to a large extent from them turning round and saying it didn't happen during their testing. It's not like it's a subjective thing like noise/vibration or the like, it will be clearly visible on a video.

I had a faulty PS4 a couple of years back and it took about an hour for the issue to manifest itself every time. The retailer in question said to make a couple of videos showing the issues and they replaced it no bother. If it had just gone back to them for testing they would have had it on for 5 mins and then sent it back telling me to do one!

Sounds to me like a dreaded capacitor issue. Capacitors can fail slowly. At first they don't work well until they have warmed up a bit. They get worse and worse and eventually completely fail. I couldn't find any information as to whether the monitor has in-built power or a power-block, but if it has a power-block I would try replacing that first.
