Do Not do any thing with Red Bulb (picture tube).
Let me ask couple of questions about picture problem.

1- Does TV show red picture separately like 3D picture effect or do you see double picture in screen?
2- Does TV give red shadow on high bright scene, specially on white objects in picture?

Let me know about above symptoms to suggest solution.

The most common issue with these model of Sony CRT rear projection TV's is faulty CRT's. the blue was the most common of them to fail. If that is the case then you are unfortunately out of luck as the CRT's are no longer available. there is a possibility of finding a service technician who can remove the faulty CRT and have it sent away to have it rebuilt. The problem is eventually the remaining 2 will do the same thing at some point. Take a few moments to rate my answer... Thank you. : )

If the picture goes Blue, it is probably the BLUE CRT failing. Sony does not make the CRT ASSY available. You must remove the BLUE CRT and send it to Sony so they can replace the CRT on the old COOLENT COULPLER. There are a lot of negatives about doing it. The biggest is the cost. The rebuild will cost about 300.00. Most of the time the RED and GREEN CRT also should be replaced other wise you will have a color imbalance. Now you are talking about 900.00. In short, it is just not cost effect in my opinion.
I hope this helps,

It sounds like you have a bad GREEN CRT.
I would not invest the amount of money to replace the CRT. It would require a Qualified Service Person to come out to your home and remove the GREEN CRT ASSEMBLY and send it to Sony so they can rebuild it. Too much time and money would be wasted. I estimate it would cost around 800.00.
I hope this helps,

If you are talking about the outer screen, it is available----part number is:


It is about 142 dollars--this set actually has three screens, this is the outer one--the inner two are MORE expensive--usually you have to remove all three to replace any of them--I can tell you the site that does sell this part--you need to be sure which screen you want--They are the largest OEM parts dealer in the world---Located in the Los Angeles area of California--allow for the fact if not for resale they will get you for sales tax and SHIPPING---

If the outer screen got a scratch or cleaned with the wrong thing it is possible to remove it and just use the other two screens--yes you will have glare if it is not there--the inner two screens deal with picture-if either of them is damaged you have real problems--

Usually someone cleans the outer screen with something that streaks or discolors it--hard to watch once it is there and almost impossible to clean streaks away.

Let me know if you want to know the place in California that sells this--they can tell you actual cost with shipping etc.

First ensure that there are no other electric devices around your TV.
If this does not solve the problem it is most probably a CRT problem.
There are three small picture tubes inside your TV, called CRT (cathode ray tube). They are of three different colors - red, green and blue. At the end of a tube is a small board located that supplies the information that needs to be displayed on the screen. Your TV has a problem in the red CRT. It might be the CRT itself or a component on the board that connects to it.

Solving this requires the help of a qualified repairman because there are parts inside your TV that are still holding dangerous amount of voltage even if it's unplugged from the wall outlet.

The self-diagnostic function of the projection TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue. As per the two examples below, some of the issues may be resolved without the need for service.
  • If the STANDBY light flashes three times in sequence, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
  • If the STANDBY light flashes four times in sequence, the TV may be overheating. To resolve this issue, ensure that the back of the TV is well ventilated.
If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
  1. Turn off the television. IMPORTANT: For a projection TV that uses an internal lamp, wait 5 minutes after turning off the TV to allow the lamp to cool before continuing with the following steps.
  2. Unplug the TV power cord from the electrical outlet.
  3. Let the TV remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the TV is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the TV.
  5. Turn on the television. NOTE: If the TV does not turn on immediately, the fan may need to finish its cycle. This is part of the cooling process for some projection TVs and is normal operation. After the fan turns off, attempt to turn the TV on again.
If the issue is still unresolved after following all of the troubleshooting steps, service may be required . Please note the number of times the STANDBY light flashes and relay that information to the service center.

The set needs degaussed this is common issue, most tv's have a degaussing coil in them, but they are very weak and will not correct extreme issues. It is possible the internal degaussing coil has stopped functioning. If this is one of these sony 40" crt's this is a big problem. and any metal near by will cause gausing of these tubes. Have a tech come out and degause your tube. A technician will have a very powerful loop coil that will clear the problem with one or two passes. But if it returns, check for perminant magnets near the set like large speakers or any other thing, this can also be caused by a child;s toy with a magnet it it if the child has rubbed it across the screen. This is not a destating issue and can be corrected easly.

Those are retrace lines, the screen controls which are a technical control located under the front gray panel of your tv needs adjusted. This also could be an indication of a bigger problem, most common would be the focus block failing. it could also be of the picture tubes failing but this is not as common or possibly the crt driver ic's. There are specific diagnositc steps to preform to isolate the potental failure. this could lead to the tv going very bright then shutting down.
The first thing a tech is going to do is to adjust the screens and leave, somtimes this is enough, but sometimes it is not. if you want to try and adjust the screen i have an instruction set below, but i must warn you that there are high voltages present when attempting this adjustment and can be dangerous if you are un familure with tv repair.

Turn your color all the way down and the brightness in the middle, then find the focus block, it will be a block with 6 controls one row will say screen the other will say focus near the picture tubes, adjust the screen controls(one control for each color) until the picture has a good black and white look to it, then turn your color up and it should look fine. This is how i balance out the picture. But there is another method that allot of techs use, the other method is to adjust the brightness up until you see what is called retrace lines it is a jagged line going down the screen, once you see these lines back the adjustment down just until they disappear. Do this for all three colors. This method works but on an older set can throw the white balance off because of tube wear.
