Question about Hitachi 53UDX10B 53" Rear Projection Television
Is their multiple ballasts / power boards. One for each lamp? If so how do I know which one is bad and needs replaced. If I have to replace 3 of them that is pricey at $200 bucks a pop.
As I mentioned this TV doesn't use ballast(s), it user CRTs and the time when you need to change one is if the picture looks out of focus of one of the colors.
You might not even need to change it, if it powers up and you can see it lighting up. These CRTs use a liquid coolant inside to keep them cool, that liquids becomes contaminated over the years and will affect the quality of the picture.
This website has a very good info on how to do it.
Why do you think you need to change the CRTs?
