I had to repair one of these for a friend when I was only good on Sony (not boasting here, I worked for 2 Sony dealers so I HAD to do them right)
The Hitachi had "Jail bars" on the left side of the picture. Still under the impression a 3 year old TV couldn't possibly have a bad capacitor, I wasted lots of time before a bad 47 mf(?) 250 volt cap was found on the CRT PCB? on the CRT's G2 supply line. This allowed horizontal-rate ripple to modulate the G2 voltage and cause the odd symptom. Once done, it looked great.

Ok, got a chance to clean it up and pop off the back cover. Not too bad inside! just a little compressed air and it's done.
 All i have to do is some detailing on the front and that should do it.Dave,i didn't see that cap on the crt board.I guess maybe on the main pcb?
