Ln55c650 keeps flashing bright to dim very fast after about 30 minutes of being on if i shut it off for a few minutes it goes away til about 30 minutes the picture never goes away just gets bright and dim...


I had the same issue occur on my ln55c650 (screen flickering, not the actual image but the front lights flashed which was too distracting) and they had to replace the power supply pc-board. Seems some issue with power module in the TV rather than the side panels. Luckily for me, TV was still in warranty.

My screen is very dim


boot to the BIOS (F2 at boot) and ensure that the LCD brightness is set to 8 and then reboot, if LCD is still dim, then, check the Control point system manager display settings and see if the LCD is dimmed there.
If no change, run diags Power + D at boot to run the LCD BIST test , if the 4 colored screens are DIM during the test, then the LCD has failed and needs repplacement.

Nintendo DS Lite, Dim Green Light, Brigher Green Light then off


Hi,

If the green light reacts as you state then the chances are the fuses are fine.

Again, with the reaction of the green light being as you stated i'm going to assume you have a problem with one of your screens, tell me... when the green light comes on does one of the screens flash? If it does then we have found the answer...

The screen that doesnt flash is the one with the problem, you can try taking the DS lite apart and re-connecting the screens ribon to see if that sorts it, if it doesnt then im afraid you will have to buy a new screen. These can befound on ebay for a reasonable price.

I have written some guides on how to change your screens and how to disassemble the DS lite, these will guide youthrough the processes you need to take. These can be found by clicking on my name and then scrolling down to "tips and tricks", press the "view all" to see all of them and find what you need.

I hope this helps.

Regards,

I have a syncmaster t220/t220g monitor, I have had it for about three weeks. It just started to dim on varous screens (random) not sure why.


If the screen is getting dim to the point where you can't read it, it might be due an intermittent backlight. If this monitor is really only three weeks old, you might consider returning it to the store where you purchased it and exchange it.

Screen Keeps dimming and contrast function does not work


Hi,
This is possibly, a loose cable or the screens inverter board is overheating. the inverter is similar to a booster in a flourescant light fitting. which converts power from DC To AC and boosts up the panels Light Tube. CFL if it,s faulty or overheating. this will cause the panel to dim.
also check the plunger at the underside of the screen, isn,t sticking down. designed to cut off the panel when the lid is closed. Finally some model laptops, only boost the brightness running on A/C Power. the battery would run-out fast with screen at full brightness. if theres an fn key on the keyboard, press fn and the brightness button to adjust screen brightness.
