Unfortunately, the Blue CRT will most likely need replacement. But you can get the entire assembly as a complete unit which makes it a easy removal and installation since the CRT is a complete one. Heres the link to that Blue CRT http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=220790336974&ssPageName=STRK:MESE:IT

I had to adjust the brightness to 100% and you can still barely see it and it has a blue tint


This TV is CRT driven and when the brightness is a issue you would need to diagnose the Blue CRT and or the Fly back transformer.

Many times the transformer is not providing enough power to that CRT witch can cause this to happen.

Without the TV in front of me it would be difficult to pin point.

Also you would want to consider if the TV is out of Focus thus causing this blue tint, Here is a on line part store that can help you in purchasing the parts for the tv if your interested in Do It Yourself repair.

http://www.partstore.com/Model/Toshiba/Toshiba/42H81.aspx?p=4&z=50&c=3b663bdcbb0b5634f5cc800d37496d25&bs=Category&bd=Asc&ms=Category&md=Asc&k=#1

First if the TV is not illuminating with the brightness function you would consider at this point the TUBE "CRT" or the Fly back witch drives them.

Thanks for your questions

Convergence issue Blue not convering correctly, but the other colors do. The blue is warped at the top and bottom of the screen. Is this problem something that can be fixed?


Yes,the covergence ICs and precision resistors can be replaced to rebuild the area. A reputable shop may charge around $300 . If you are technical person,I can guide you further to do yourself!

Samsung pcn5425r faded blue?


You either need a new Blue CRT or the Blue CRT circuit board. You can get both those parts at the following link for a real cheap price as they have them used which cost a fraction of what they would be new. Leave them a email with your model number and what youre needing they will respond back quickly.

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.
