Screen blinks - sometimes shrinks & disappears and then re-appears
I've seen this problem with CRT TV's before. I've a 9 year old Mitsubishi Diamond Pro 710 monitor that has worked perfectly until now. But it now starts to play up by shrinking the screen, sometimes disappearing the screen whilst "blinking" and then having the screen reformat itself back into a normal trouble free screen. Can't see any answers as to what to do in the Troubleshooting Guide in the manual. Any ideas anybody ?

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.
Your monitor is overheated and has blown the tube. The only way to fix it is to throw it away and get a new one. Your not supposed to leave your monitor on all the time especially with a game just paused on the screen.
I thought my problem was originally monitor related. However since I posted, the picture disappeared altogether, and my PC wouldn't even start to bootup. Fearing my mobo may have died I removed the hardware components, cleaned then re-assembled them. After all that, it turned out that my graphics card has a tendency to become slightly unseated. Once I was aware of this problem booting up resumed normally. It seems that the problem of the fading monitor picture seems to still occur, but soon after I use the machine after 'hibernation' state, and even then it doesn't always occur if I do use hibernation. I haven't used hibernation for a little while and so far the problem has not returned
Yes, absolutely know that one. It is a problem with the hardware in your monitor. I had the very same problem, there is no tuning or anything else thats going to fix it. Hopefully, you are still under warranty, well since it's six years old probably not. Since LCD flatpanel have dropped dramtically in price, I suggest you get a new LCD. The cost and trouble to fix it just isn't worth it. Best.
first of all you will to replace those buttons
as its useless after few years.
as per your problem is concern you might see some change after replacement.
still it does not work then there is a video problem
1 crt filament supply less
2 voltage on g2 is less .
3 check voltage on video ckt to be normal.
4 crt base loose.
5 there might be crt weak if it is old.
hope this will help.
well first af all ,you never find this "loose wire" because it is a mith.
what you have is a "cold solder" in the vertical IC, if you have a solder iron , and the ability to open it (without scratching),
and then take off all the shields (without cutting your fingers), and get the solder area (without breaking the Tube).
at this time ,it take you 1 minute to solve...!!!
iF not... leave it to the repairman!!!.
