WoW a 10 year old Hitachi TV. I was authorized for these sets. The problem could be one or a combination of many problems. These sets have the stand up type regulator PCBs that went bad all the time! Also could have a Power regulator IC defect. A sweep power supply problem . The flyback did go bad once in a while on these sets. If the set got a power surge, thers like 5 IC's that pop and 12 Diodes that short along with the display IC. If your not a tech You shouldnt attempt to experiment with the set yourself, so It probably wouldnt pay to fix this set If you have to pay a tech to work on it? It all depense on how good the CRT's Are. If you can get a servicer to diagnoise it at a decent price and check the condition of the tubes, Maybe it would be worth investing some money into this set, as these are or were very very good TV's. The balls in your court now. Good Luck

Tries pushes the power switch on the remote few times,each times push wait like a 1 mins or 2 mins for the tv Tuner signal board to take it effect.This process should get ur tv picture back,because the tv Tuner signal board it is old and having problems,evenually require replacement of a refurbish tv Tuner signal board.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish tv Tuner signal board for the replacement.
You can't. Either it came with them or not,.....yours didn't. It's like wanting to make a black & white tv into a color t.v. Although I used to get that all the time.....It's just a tube you pop in!!!! Sorry, the set has to be designed in the first place with that.
