After booting up my pc (currently being built using various bits and pieces that i can find) the led on the monitor changes from amber to green & the screen comes on including boot screen etc.
PC boots up and will run fine for about 5 minutes, then the screen goes blank. Turning the monitor off, then back on brings the screen back but goes blank almost immediately again. Shining a torch at the screen shows that it is still working. I'm assuming the backlights are working (as they stay lit for the first 5 minutes or so) and that the capacitors(?) running them are overheating or something causing them to cut out. I can't afford to buy another monitor at the moment so want to fix this one myself but need a detailed walkthrough so i know exactly what i'm doing. Any help would be greatly appreciated.

Re: Screens works for 5 mins then goes blank!!!!!
It could also be that the video card is not compatible with this monitor. After the pc boots up, can you get into windows? Does the monitor always go out at a specific time on boot? Say for example; you boot the pc, windows startup splash screen comes on; screen does a quick flash and goes blank. Then it maybe the BIOS setting for the video. Try changing the IRQ setting. You could also try putting the video card in another slot. Do you have the manual for the motherboard?

No, not worn out batteries. For my experience, if the batteries were worn, they would charge with the blue led being on and after that, the vacuum wouldn't hold his charge. just that. This is a different problem. Check the contacts between the charging station and the vacuum, mines got bent a bit and stopped making contact. This has happened twice and just fixed it about 30 min ago. That is why the led first lights and then goes off, there was just a brief contact between them. Nice vacuum, very powerful and handy but maybe it is just poorly made as it is engineered in Sweden but built in China.
Windows is treating the "internal" screen as separate from your "external" screen,
i.e., you've seen computer-geeks with two side-by-side screens, with the Windows Desktop
spanning both screens. With a bit of "tuning", you can nominate the "external" screen as the "primary" screen, and thus see the Windows Desktop (which currently is showing on the "internal" screen). Or, for about $100 plus $60 labour, replace the LCD screen on your laptop with a "pre-owned" LCD screen.
Change the SMPS, preferably with 450 & above wattage. Also you must be using an UPS(uninterrupted power supply or battery back-up so there are no chances of voltage fluctuation. At the time of changing the SMPS also remove the RAM and clean the contact points with a piece of normal white paper..............sodeep
The problem is not yet serious, no parts yet to replace. That is a result of a "cold solder" of the parts inside. Open the case, clean it with a soft brush and look for these cold solders on the circuit board... resolder what you find and check every pin...
see picture, the rings are somewhat the start of disconnected pin from being soldered.
After that test the monitor..... That's it... Fixya me okay...
All your doing in the bios is changing the boot up sequence to the drives?. If it was FN key and F5 similtaneously then Im baffled. In my machine its the FN and F4 together or at the same time and the screen goes back and forwards or both stay on.
This is an issue with IC 803 on the Z board. This is a 3.3 V regulator that supplies this voltage to the slot card cage. Most input boards use this voltage EXCEPT the component board which is why it keeps playing along whike the DVI, HDMI, or composite signals will cut out after warm-up.
This is a surface mount multi-pin IC and is a bit tricky to replace. The entire board is PN# TNPA3198xx with suffix determined by what model 7 series plasma you have.
This was a problem from around Nov. 2004 to Mar. 2005
