Question about Mitsubishi WT-46809 46" Rear Projection Television
Hello, I recently had a this 42" TV model vs-42oca given to me as it was replaced with a newer model. I was told that the picture was not bright enough and it had a few problems with darker or night scene's. I popped the back off to see if there was an internal adjustment for contrast and brightness, when I looked in I noticed that the Blue Gun was not working. My question is, would there by any chance be a Fuse that could be associated with this module, or is there something else that could be wrong ? Or is the Gun basically shot ? If so, what are they worth to replace, if a person can even obtain one since the TV is quite old. I have also tried to unplug the blue on the board and insert it into the Red and Blue hook ups to see if I could get a response from the Blue Gun, but it would not respond. :-(
Any help would be greatly appceciated.
Blue crt gun is dead... it has to be replaced. Check carefully the gun neck if theres a crack or damage, I'm suspecting an overheating yoke ( a bunch of wires around or embracing the crt gun's neck), if theres a sign of overheating, you need to replace the yoke too, not doing it, your new gun will suffer the same fate of the old one, wasting your money.

Tips for a great answer:
Your TV has a light sensor that changes the brightness of the TV based on room brightness.
It's called an "Intelligent Sensor"
You can turn this off in your "Picture" settings.
Congrats on such a nice TV purchase.
