Flickering monitor at startup...

Sort of strobe like for the first 30 secs pretty much every time I turn the PC on. Is this a sign of a monitor going, or mobo/gfx.

I replaced the gfx card 6months or so ago with a ATi HD 6870, so hoping not that.

I've checked and can't find any external connections loose, but it always seems to be on start-upo, or when the screen has powered down due to inaction...

All thoughts cheerfully filtered and the half-glass empty sidew will be seen...

My old monitor did the very same. Flickered like crazy when it came back on from standby or first switched on.

Sometimes it wouldn't come back on from standby and had to reboot. Once I had it on it was perfectly fine.

I upgraded and tried to get it going for my dad but it just wouldn't have it. Pretty sad because it was a lovely monitor :(

Ok, even after the pc rebuild, the screen still flickers like mad at start-up. Once it's heated up, it's fine though, but I guess it's all downhill from here.

So, just fr when things do fall over fully, what brands should I be looking at.

I currently have a 21" samsung, which has been really good up until now.

But I was wondering are the asus screens good - http://www.amazon.co.uk/dp/B004T2LMP2/r ... pe_vfe_dt2 - as asus seem to have a good name for laptops these days, including screens.
Or what about this acer - http://www.ebuyer.com/341650-acer-p246h ... -fp6he-a01

Other makes that are worth looking at?

It seems that 24" seems to be the sweet spot cash wise now, only question, is will my HD6870 be able to drive it ok? I'm not that worried about having to run everything at top sliders, and the 24" seems to be the same res as my 21", so that means it should be fine, right?

My 6870 does just fine at 1920 x 1200 for everything I've used it for.

Your 6870 will laugh at anything as low as 1920x1200, or the sadly far more common 1920x1080

You can pick up LED backlit 24" screens for well under £150 these days, even Samsung and ASUS screens. You're always going to get something semi-decent from the likes of them, and given everything is still TN then I wouldn't worry too much about which one exactly.

This will most likely be a capacitor that needs replacing on the monitor's power supply circuitry. Seen this a few times where there are bulged capacitors.
e.g.

The only thing is finding the capacitors, most are fine but I've got an old one that I attempted to fix, and a) I can't tell if it's bulging or not and b) I couldn't find a replacement for when I looked anyway.

Marvellous, another problem solved and only a day over a standard tech support 2 year response time.
