Question about Dell UltraScan P1110 21" CRT Monitor

1 Answer

Weak red and green color of Sony GDM500PS

Last week, my GDM500PS got the deflection problem. As most people suggested in the Web, I replaced the IC007 (CXA2043Q). When I powered up the monitor, it is OK initially. However, after 5 minutes or less, the red color is missing and the green color changed to greenish yellow. At first glance, the red gun is dead. But the white color is still white (that is, RGB is OK). It seems to me that the new chip causes the malfunction or wrong color processing of the monitor. Do I need to use Sony DAS software to tune the monitor or is there any simple method to adjust it? Thanks.

Sont Projection Tv colors


Your red tube is weak or defective. If weak, gain can be adjusted up on the red tube.(cheapest cost) If red tube circuit is defective that will have to be fixed by a technician.(cost between $100 to $200) If tube is worn out, it will have to be replaced(250 to 500). Any work should be done by a qualified tech. Prices will vary depending on your area.
If set is over 5 years old, I recommend replacement.

My LCD projection tv(KF-50E200A) displays projection lamp week when switched ON and out of red color display on the screen. Is this will happen if the projection lamp is week?


no and yes
the lamp warning is to alert you that a timer has expired that clocks the approximated life of the lamp in "hours of use".
it is never accurate and is dependent on whether or not it was reset the last time a lamp was replaced.
reset the lamp timer in the users "setup" menu.

the lamp has NOTHING to do with color, it only provides light.

check the connections between the TV and cable/satelite box...the red.green.blue component connector...the red one is likely loose.
if this does not correct you color problem, your optical engine has failed.
very expensive repair, not for the DIY type guy.

On a white picture my screen has a yellow color to it and at times mill have a blue blur on the bottom left corner of the screen. also i get blue dots in the middle on the screen.


Hello: Seems like you have a picture tube problem. The yellow color is from a weak green crt. I suggest replacing the Red and Green Crt's in this model. They are nortoriuos for Failure especially the Red. The cost for these tube vary from 110.00ea to 150.00each. I don't know if you want to spend that type of money on this set, as i Know this peticular set has an expectional picture quailty, my experience with replacing sony picture tubes, is to replace all three tubes, as the new ones will show brighter. So replacing the red and green crt's and not the blue is not recommened. But thats up to you, you might not notice the color difference yourself. You also have the option of sending the Crt's for refurbished ones or having the originals rebuilt by a company in Calif, called VDC, Video display Corp. They sell and refurbish sony CRTs. This route is much cheaper, the only problem is having the crt's taken out and sent for repair. The other option is to think about purchasing a new set. As this repair price could reach into hundreds of dollars, Around $600 to $700 for parts and Labor..

Color is terrible - lot of green


If this is a CRT type most probably loosely connection of the other color gun. Commonly attached to the backend of the CRT.Dust problem or transistor is busted for color red and blue. Or some minor component connected to driving color.

There is an extended warranty on the optical block which is causing your problem. Contact Sony directly at 800-222-SONY to arrange to have a technician look at the TV and have the optical block replaced. Sony is covering parts and labor for this repair. For more information visit the Sony website

Red hue on TV


I have the same problem. Researching a replacement lamp. After 5 years the lapms expire and it is the most likely failure. Confirm with a local service person using the Sony website to locate a service center.

Replacent in not difficult but the bulbs are >$200. Cheaper than a new TV.
