Question about Sony GDM-W900 24" CRT Monitor

1 Answer

Sony 24'' CRT widescreen GDM-FW900 blurry after initial on

Not every time, but frequently, the screen will become blurry shortly after turning it on or having it recover from standby. This will last for 10 minutes or sometimes significantly longer, until the monitor loudly "pops" and all is crystal clear again.

I'm not sure what the specifics of the problem are, but I know of another person with the same monitor having the same problem. Secondly, even if I can identify the problem, I'm running into difficulty finding ANYONE who repairs CRT's in KC. I'm tired of the line "they aren't worth fixing" as this monitor is still state of the art for a CRT, has benefits in adjustable resolution, color, and video over LCD, and just 5 years ago was running between $1450-1800.

Help me save my CRT!!!

CRT shorts are common with this model and focus problems are a major symptom. however, the loud 'pop' you described leads me to believe that the flyback transformer may have a problem in the focus divider portion. replace the flyback, if that fails then the CRT is most certainly the problem

I too would like to know the solution to this question...we are having the identical problem and Sony doesn't seem to know how to fix it. Although, the picture from the DVD player is perfect, the pictures for cable & video games are terrible. Very frustrating!

Pop - bang noise then went dead after a period of time


You've blown a capacitor and probably the horizontal output circuity. It's time to get a new LCD monitor.

Sony trinitron xbr red diagonal lines appears then screen turns red and then shuts off. The red led light blinks 7 times. Please Help!!!


In cannot remember if this model of set uses on the CRT drive board a drive IC for the CRT colour channels, or if it uses descrete transistors. I have had component failure on this board that causes your description. The failure in your case would be with the red channel drive. Most of the time I had the semiconductors fail, and some of the support components.

Most of the time, a failure on this board is caused by some intermittant internal arching inside of the CRT. If this happens, the CRT is starting go defective.

Another cause of this fault is that the CRT is starting to go internaly shorted between the control grid and screen grid. As it heats up, the shorting becomes lower in resistance, and thus causes the pricture to go brighter until the protection turns it off. This would be with the red electron-gun.

With any failure with the CRT, the set is not worth to fix even if you can find a CRT for it.

I have a Samsung CRT slimfit that I bought in 2006. It has worked splendidly until about 4 months ago and suddenly I have started to notice the edges of the screen about 2-3 inches on both sides have...


In my experience from doing Samsung's warranty work on slimfit sets, they have issues with picture tubes causing problems on the circuit boards. Many times I would replace a board only to have it fail a short time later. The wide crt draws a large amount of current and many have purity (discoloration around edges) problems. I would suggest you try contacting samsung to see if any recall exhists on these and if that doesn't work I wish you luck having it repaired properly for under 275.00

Blurry/Hazy picture on Philips Tv


as your problem is the picture has become blurry/hazy 1 it sounds me that there is a little sparking near high voltage section that is near flyback transformer.please get it check. 2 if it is ok then focusing anode wire going to crt base from flyback transformer is not making proper contact due to some foreign material deposited on it. please call tech person if you ae not aware of it as tv is a very high voltage device.
