I have a Hatachi 50" ultravision HD tv (sorry,no model #)that has begun to loose focus, (Blue and Red) outline of the picture screen. Upper right screen is seems ok. Have used manual went through the Magic focus with no change. What can be done or is it worth having tech to fix. I had it about 3 years, TV is about 7 years old. Any help appreciated.

I presume you'd like exact location numbers, part numbers, etc.

Hard to google, look up prior repairs, etc. when Model Number = NONE.

Will be on the rear cover and is usually repeated somewhere inside the set.

Replace the STK392-110's and check for any open/changed value bias resistors.
