Title: How long is too long for a monitor warming up?
Post by: channel27 on November 01, 2005, 05:53:12 am

Apologies if this is a dumb question... :-[ ... but do all arcade monitors take a few minutes to "warm up" or is this a problem which get's worse with age and is fixable?

My monitor has a Mitsubishi tube with a Nanao MS8-26U chassis and when I fancy a quick game on the machine it's in I turn it on and find myself waiting for 10minutes before I can kick some Akira butt (The game is VF1

10 mins is too long--a minute or 2 maybe depending on ambient temperature.  I've been told a cap kit helps alleviate the problem but I've never been in your situation so couldn't say for certain.  You might also want to talk to jomac as Nanao's are his specialty and may know of a reason that is particular to that brand of monitor.

Technically many tv and monitor service manuals tell the technician to allow the particular tv or monitor to warm up at least ten minutes before performing any adjustments. It gives time for all components (including the picture tube) to stabilize.

Every picture tube and every component ages differently in any tv or monitor. If you are stating that it takes ten minutes before the picture is bright enough to see clearly then you either have a weak picture tube or need some capacitors.

Thanks for the replies,
I get a picture after a few minutes, but for it to get to "full brightness" takes about 10. It is very cold where it's being stored at the moment tho, as my heating isnt working, so maybe that's a contributing factor? I blame the weather here in the UK! ::)

also here in the uk (cold stored)
my machine has the monitor up to a viewable screen just as the bios goes off screen (10 secs) and full brightness about 5 secs after that

old hantarex 20" monitor with nice new flyback, have not capkitted it yet as apart from the dud flyback there has been no issues. (checked loads of caps before diagnosing flyback)

Hi all,

This is a question I've been meaning to ask for a while and this thread is right on topic.

I have an old TV which I'd like to use for an arcade cabinet but the darn thing takes anywhere from 10-20 minutes to come on. By this I mean that, I turn it on and nothing happens (no picture at all) but after a length of time (10-25 minutes as stated ealier) it just fires up and everything is fine. Is this a sign of a particular component going bad or is it a capacitor issue?

Thanks,
Breaker.

With a tv set it could be anything like capacitors, bad solder joints, relays, sleep timers, remote control circuitry problems, etc. I would suspect as likely culprits though would be capacitors and bad solder joints with caps as the number one suspect. Go to the newsgroup sci.electronics.repair and post your monitor's brand, model, and chassis number and one of the professional tv repair techs may have some tips for you to check out.
