JTS1957:

Thanks very much for your reply, fortunately it is still in warranty and it is being collected this pm, for a no quibble exchange, great service by iiyama.

Also: you appear to be specifying another model.

Have you checked the power supply capacitors mentioned in the thread?

Afternoon, I know this is an old thread but hope someone might be able to throw some light on this please for me?

I have the above monitor but the blue power light doesn't work. That wouldn't be a problem in itself, but the monitor goes on the blink occasionally like it did ten minutes ago where the screen kept on turning itself on and then off ever couple of seconds.

Any thoughts very much welcomed.

Thank you.

same issue ,iiyama e2208hds, blue led flashing, delayed display on boot (10 minutes delay), capacitors 706 and 707 domed,(16V 1000µF) replaced with 25V 1000µF: So far so good .Thanks to previous contributors.

I have exactly the same monitor which had also gone completely blank with only a blinking blue light. When inspecting the circuit board I found the tops of C914 and C915 discoloured and slightly domed.
I replaced these with two 1000 micro farad but a higher voltage, I think 25V, the original were 16V. I think it a good idea to make sure the temperature rating is also 105 deg C. They just seem to fit in nicely.
So far so good.
Thanks to the other contributors who have helped me tackle this with some degree of confidence.

Also i my case with mentioned supply problems replacement of Capacitors C914&915 did the trick!!

Also after this sentence:
After a while (~10s) the monitor goes to standby, no noise from PSU any more, and strong orange led shines.
- the voltage rises up again.

Thanks

Hello, I know this is an old thread, but my iiYama ProLite x486s monitor has just stopped working. I have tracked it down to be (probably) power supply / inverter board issues.

The monitor is dead. When assembled (in plastics), it only shows orange (sstandby) LED. It's supposed to show blue led when ON. This led shines, but shines so little, that it's invisible through plastic.

When disassembled, the blue led is visible - faint - and display is dead, no picture.

I have found this thread and found L101 (on mine it's L901) dry joints. Also found dry joints on other places on the board. Resoldered - no luck, still the same. Capacitors are OK. Board is visually OK. Transistors are not shorted.

The problem, I suppose is that on the main connector (to monitor main board), the voltage on pin 12 is 12V when in standby - however when turned on (faint blue led shines), the voltage drops to 9V. On pin 3 (5V line), the voltage drops to 1V. I think the monitor wants to display "no signal message", because after a while it goes to standby again (strong orange led shines) and the voltage again rises up to 12V/5V on said pins of connector.

I'm just guessing here. Also, when I press the power switch on the monitor, the PSU (don't know which part) makes a high pitch / frequency noise for about ~2 seconds [voltage is now STILL 12V/5V BUT blue led shines faintly anyawys], after this period the noise stops (complete silence) and the voltage drops. After a while (~10s) the monitor goes to standby, no noise from PSU any more, and strong orange led shines.

This repeats when I turn it off via power button and on again.

It just completely died all of the sudden. No issues before whatsoever. Any help on what parts to check or what could be the problem is realy nice.

Also, the psu partn number is 715G1236-3-AS, but I have been onable to find a datasheet for it.

Thanks!
