Question about Computer Monitors

I have to heat up my CRT

My problem - Relisys TE770-RU 17'' CRT Monitor

When my monitor was working correctly, I would plug in the monitor, the green power light would come on for a second, then it would turn amber (power down, I believe).

Now when I plug the monitor on the power light simply flashes and there is clicking noise, I have to repeatedly turn the monitor on and off at the plug switch to get it to eventually come on properly. I noticed this was worse in cold weather or in the morning when it was cold.

I tried an experiment, I placed a fan heater a couple of feet away from the monitor and switched it on for 15-20 minutes then turned the monitor on, It came on as normal. I've tried this a few times now, even in the morning and it comes on as normal. So when I warm my monitor up in this way it works as normal.

I was wondering if anyone had any ideas what the problem might be.

Re: I have to heat up my CRT

It is a weak cathode heater inside the CRT. One fix, besides what you are doing, is to replace the glass tube (crt) inside the monitor. Unless you can find a used one, may be hard to find now. It may also be possible to supply the heater filament with a separate supply. I believe this requires a 6 volt supply, so try adding a 10 volt (FUSED- 2 amp) supply to the filament only.

Can you send me a manual for the relisys monitor model c708

This is not a store. It is a site for getting helpful tips.What type of manual are you looking for, a user manual or a repair manual? If the latter, I think you are wasting your time. Though this was a good monitor in its day, it is just not worth repairing. It is hard to even give away a CRT monitor these days.I recently gave 40 brand new boxed TE770 to a charity, because nobody wanted them at any price.
Have a look in your local papers and pick up a bigger crt monitor for next to nothing. Then get rid of the one that you have.

Crt Monitor Macer Model C708 as soon as i connect the power cable there is no power, no display

Have you checked that power is reaching your PC? First, check your power socket by plugging something else in. Next, you need to check the monitor's power line.If it has a fuse in its plug, check that by substitution if you don't have a test meter.It is very unusual for the power lead itself to get a fault because monitor power leads are heavy and of good quality.
It is possible that an internal fuse has blown, but if it has, there must be a cause. I would not advise you to even check that due to very high internal voltages even when power is off. Unforunately, CRT monitors are worth so ilttle these days that they are not worth repairing. Your best bet is to find a used monitor locally, which should not cost you much because they can hardly be given away these days.Look in your local papers.

2. Open your on screen display and go to Volume settings. See if it set on mute or set to 0.
3. Turn of your monitor & PC and unplugged all the cables from your monitor and PC wait for 10 seconds and then replugged it all the cables and audio cable back. Then turned on you PC...
4. If it still doesn't work.. open the back cover see if the speaker cable are plugged in.
5. If that doesn't work...then your monitor AD board built-in speakers are defective.
6. Why not just used a external speakers, it give better sound quality.
Have a nice weekend!

some how your screen resolution has changed above or below what your monitor can display. you need to boot your computer using another monitor that can work with the resolution your computer has switched to(i used a spare crt monitor when it happened to me) change your resolution in display properties to a normal level like 1027x768, and while the computer is on swap the monitor cables to verify the lcd is working.
It is perfectly safe to unplug the video cable and plug it back in while the computer is turnned on.
