Lost the green tube where do I find one? The color is either red or blue on my set.


Need the model number of the tv. Are you sure it is the tube itself? The fluid in the CRT may have turned cloudy and need replacing. Check to see if the bulb is glowing in the CRT neck. Can you see any light coming out of the bulb?

If you need to replace the CRT, it is always recommended to replace all three in order to keep the colors balanced. Look on Ebay for a used CRT. You need to get the part numbers off of the CRT assembly, usually located up near the face of the CRT itself.

Turns on for 30 sec then goes bright blue and goes back into standby. turn back on it does it agian


This is blue CRT problem in tv as it is rear projection tv that has three CRTs red-green-blue inside to project color picture on front screen.
Blue CRT (tube) will be replaced to fix the issue and it is job of Pro because lots of adjustments are required after replacement of tube.
Local tv repair shop will help you for that.
Thanks

53 inch projection tv...seems like the color red and color blue have shifted giving me a picture with red and blue shadows


For CRT projection TV's, this indicates that the Green picture tube is burned (warn out). The less green that strikes the screen, the more redish the image will look. You will need to find an old school TV repair shop that knows how to replace picture tubes.
In the case of a DLP style TV, the color wheel needs replacing.

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..

Screen goes all blue


if it is a KP65ws500 it is one of a group of sets made by Sony where all the picture Tubes(set has a RED, Green, and Blue Tube.) ARE BAD. Most of these sets had all three tubes replaced during a program Sony had. The tubes are NO LONGER AVAILABLE---the only way to get one is remove the tube and send it out for rebuild---most of these cost about 250-300 just for the tube.

The set is shutting down because when the screen goes bright blue it detects one of the CRT's(tubes) is pulling way to much current.

The problem with Replacing your Blue Tube is cost and----sooner or later the other two(red and green) are going to fail also.

best advice is maybe not to fix it.

I replaced dozens of the tubes in these sets when Sony had a recall and provided the tubes for free and paid for the labor etc.

I know I am not giving you good news but I do this here for free and if this has been helpful give me a vote here. Thanks!

Bulb Replacement


It might be the the socket board on this model not the crt tube. Closely look at each tube these tubes end up contaminated. They start looking like lemonade inside. Usually the blue and green, with the tv off see if the green and blue are as clear as the red with a flashlight. You might want to call a service center. Cheaper in the long run over the cost of a tube.

No blue manual convergence - Samsung pcj522r


Thats a very strong possibilty the phosphorus may be burned off the CRT face. Does the blue project when powerd up and looking in from the raer of the set? Look into the blue CRT lens while its playing If you can see a clear picture I would think that you have some open resistors in the blue circuit, If you cant see a picture its time for a CRT. If you need a CRT let me Know I have a good source for them Used.

You have a bad blue picture tube. If you replace it the red and green will be weak and probably go sooner than you think. Everytime I had to replace a tube in a sony projo tv i had to replace all 3 picture tubes at the same time. It's very expensive if you don't have any type of warranty coverage.
