Query for Malcolm or another expert re monitor.

[del320]

My aging Mitsubishi Diamond Pro 720 has recently been going dim intermittently - white takes on a yellowish hue. Turning the brightness from 80% to 100% compensates but then, of course, it's too bright for me when it reverts to normal.

I've done all the technical things - wiggled the connections, turned it off and on, hit the casing and put another 50p in the meter .

Is my monitor on the way out?

(See, it's just gone bright again )

The only thing it can be will be a dry joint somewhere, the hardest thing on monitors is the dismantling the shielding covers, the fault could also be on the tube PCB, tapping around with a screwdriver handle should give an idea where the fault lies

You can pick up used monitors for next to nothing on eBay. I have a 22" Iiyama Vision Master which has the Mitsubishi Diamondtron tube, and I got it for £10 - it was local pickup (15 miles) so cost very little. It is almost new.

I am a photographer and find that LCD flat screens are almost useless for critical photo editing. The older CRT screens are much better as they display a much wider range of tones.

I also got a near-new 17" Iiyama Vision Master from my local Freecycle web site. Freecycle is a worldwide network of web sites where people advertise their unwanted items for free, rather than take them to the tip. There are adverts for items offered and items wanted. The Freecycle sites are operated as Yahoo! Groups.

The whole point of Freecycle is that things don't get to the tip.

But I might have expected that you would miss the point.

I did not miss the point I found it hard to follow,, the recycling plant near me Honiton is 1 mile away from Honiton freecycle. Nothing goes to landfill in the way of computers and TV,s and at least 50 of each are thrown out weekly, this does show that it is not working that well.

great useage on recycling wish we had things like that around here

Thanks everybody.

It looks like it's giving up then. No problem, I'll look around for a new one in the New Year.

The Mitsu was certainly considered a good monitor when I got it and I agree with TonyE300D that CRTs still have the edge for colour resolution.

Again, it's fine just now!

try argos they had some good deals on lcd monitors

I bring them home from the recycling center and fix 5 out of 10, many smaller ones are thrown away when they buy a larger one

A small warning

For those that don't know and are thinking of some DIY on a CRT monitor I copied the following message from another site:

"A CRT monitor has *VOLTAGES (up to 20,000) THAT CAN KILL YOU* and can hold that charge for days, weeks and even sometimes months AFTER it has been unplugged."

We got rid of 3 17" crt monitors last year as we were running out of desk space, we spoke to the local council & they run a charity where the monitors are allegedly picked up and given to people who need them (developing world & photographers ). They were very specific and said that we need to put the screens out the night before as the collection could be very early the next morning. When I suggested that this would not be a good idea as it was raining (ie the electrics would get damaged) and could we not get the guys picking the stuff up to knock on the door when they turned up, she replied that this was against regulations but we shouldn't worry as they pick up in the rain.....

I noticed the next time we went to the recycling centre to drop off diy waste, there is a skip full of crt monitors exposed to the elements - presumably to be shipped off somewhere to help someone..... or perhaps more usefully to be stripped and recycled..

TV's can have 30kv in them, just the same as monitors, the storage of the high voltage is done through the thickness of the glass on the bowl of the tube you have a graphite coating on the inside coupled up to the high voltage, and on the outside the graphite coating is connected to ground. this is the same as a giant capacitor.

I get the odd shock from time to time, but when you know what it is, it is not a shock.
I had one the other day, a Grundig that came from a damp house, when I turned it on you could smell and hear the corona, my hand was on top of the set and a sheet of flame leapt some 6" to my hand. My hand smelt like roast chicken for some hours, and it always makes me hungry

I'm interested where you get rid of them to? I have just dumped a 17" monitor (pretty near brand new) because nobody wanted it - the charity shop cannot take it even though I would have PAT 'ed it before giving it to them, the school likewise , and it ended up going for "recycling".

I would agree about not messing with CRT's unless you know what you are doing with flyback transformers and know where to find your front porch.

In theory thay shouldn't unless to trade buyers (which you are).

My old boss used to work in a radio tech's and they at that time used to put all the radios they had in the auction - his job was to take all the valves out, disconnect the mains lead and tie a knot in it - it went to auction , didn't work , got taken for repair , and the idea was that the customer got sold a new radio. Who knows? nice story though.

Sounds like you might have picked up that Ilyama from me I recently put some on freecycle

I think I still have a few 19" Ilyama's in the garage along with some 19" mitsubishis... (I kept them as spares should mine die - I am worried that producers will stop making CRTs...) del; should you be around Uxbridge anytime soon you can have one of mine!

My hand smelt like roast chicken for some hours, and it always makes me hungry

I found that severely burnt flesh smells more like bacon/pork than chicken
