The tube will be around 400.00 and then the repair tech will want maybe 150 to install. Try this link they may be able to get you one some what cheaper and give free tech support so you could install it yourself.

Screen goes blue


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,

Blue screen when watching tv


hi,
i contacted toshiba and this what they have recommended, i am concerned whether it will be cost effective to repair.

''The Blue CRT is being driven at maximum brightness, it could be
components in the associated drive circuitry or more likely an internal
Short circuit of the Blue CRT itself.

I have not rectified the problem but would be interested in the cost of repair if any can give me an idea

Hope this helps others as well

regards

chris

Toshiba 46H84 Blue CRT Misaligned


The problem is you convergence IC's. STK392-110. If you are not experienced I would contact a tech to do this work. Repair costs should be 200-400 depending where you live.

Blue crt assmbly maybe?


its very possible that the blue CRT is horting the set out. Heres how you can test it. Remove the speaker grille and access panel behind the grille and you will see the crts. remove the blue crt circuit board from the end of the blue crt and make sure it isnt touching anything then try powering up the set if it doesnt shut down then you have found the problem and you will need a new crt. or you can switch the blue circuit with the green and try it iwth the blue on green and the green on the blue then if the screen turns green before shutting down you will know that its a problem in the blue drive circuit and not the crt. lety me know if you need further assistance.

burn in is caused when the phosphorus is gone from the face of The CRT . The only way to get rid of it is to replace the afected CRT or have it rebuilt. CRT rebuilders are hard to locate and most rebuilders are almost equal to what a new CRT would cost.
