Re: blury ,double vision, and cant brighten up
Your TV has a convergence problem. Here are some of the most common symptoms.
Screen looks 3D One or more colors can't be adjusted when using the convergence menu. Screen is bowed in or warped.
Here is a quick test....
Using your original remote go-to the tv settings then goto the convergence or magic focus section.
Try to adjust the convergence.
You should be able to move them up, down, left, and right.
If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.
Its a fairly easy fix on the Hitachi sets.
You can get a repair kit that includes all the parts from www.TvRepairKits.com. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.

There seems to be two problems with the unit. The first symptom indiates your convergence IC's needs to be replaced. The second symptom coud be a several things, 1. Bad connections on the Crt board of the green tube, 2. The 200v screen bias voltage supplied by the flyback could have bad connections on it. Seems you have intermittent cold solder joints. Check the D board around the Flyback area for bad connections, or old grey looking solder connections all should look shiny. 3. The Green Crt maybe going faulty, the lines going thru the picture are scan lines and indicates that the Screen controls are to high. But i know you have'nt adjusted these so i would suspect the Green Crt is Faulty. But check solutions 1&2 first, One way to find out if its bad is to unplug the green crt board from the tube and turn the set on if it stays on and does'nt shut down then it is faulty, also while turning on look at the crt's neck for sparks which indicates arching in the tupe and will need to be replaced. Replacing the Convergence IC's will solve the distorted pic issue.
The double vision is from bad convergance ic's and posibly some support resistors or pico fuses. if you are not an electronics tech I suggest to have one do it. the ICs can range from $45.00 to $60.00 each and is suggested to replace both of them. some mitsies had one IC which I cant remember how much it was. tech charges vary. some prices may be $150.00 to $300.00 shop around.
