Does the Asus PG27UQ board seem damaged or worn out?
Does the Asus PG27UQ board seem damaged or worn out?
Hey everyone, back in 2018 (or around 17 years ago?) I purchased this new monitor – it had impressive HDR capabilities. But soon after, it began to shut down whenever the temperature rose, right before the warranty expired (three years). By that time I’d moved from the US to the EU, and the warranty wasn’t honored. Sadly, Asus refused to repair it, claiming they only replace the unit in your area with a new one if there’s an issue. Still, I managed to send it to another region at my expense, and eventually the repair shop replaced just the heatsink fan – though the second one was left untouched. In the end, I got a spare fan from them to keep on hand for future needs.
About three to three months after it arrived, the same problem resurfaced. Over the past few months I’ve tried some makeshift fixes – like directing outside airflow onto the monitor – but as temperatures climb it keeps cutting out. So I decided to take it apart for inspection and cleaning. To my surprise, there’s a second fan inside that wasn’t replaced by the repair team before. I swapped it out using my spare unit, and at least it’s quieter now.
What really caught my eye were strange markings on the motherboard beneath it. I’m not very familiar with damaged boards, but these look unusual. The repair center never mentioned anything about them. It seems like something was wrong – maybe overheating? Overall, the monitor works fine when you ignore these three issues: 1) It powers off when temperature exceeds about 22°C – unplug and plug back in to restart; 2) Sometimes the LED menu icon appears unexpectedly after turning it on; 3) There are times when it shows no display at all, which resets by pressing the power button again.
This has been happening since the start. I’m curious what others think. Another thought: Linus might want to make a documentary about these kinds of devices – they seem amazing at first, but after a few years they fail and parts become hard to find. Plus, companies like Asus just tell you to stop using them. This unit was listed for over $2000, so it’s definitely a big deal.
It doesn’t seem bad, just dirty with likely flux residue. The board I fixed today was quite unpleasant. I’d probably check the power supply instead.
