It is the protection circuit cutting in and shutting off the set. This is because it detected a short or near-short circuit somewhere within the 8 or 10 sections of the set. Most common is high voltage, deflection amplifiers and main power supply.

You must know how to troubleshoot the circuit and systems in order to repair these kinds of set. You can get lucky, sometimes, by just probing around looking for something that does not look right.

If you are an electronics technician with some good skills I can give you better advice, but if not, you are better off seeking professionial help.

Its possibly a fault protection which automatically turns the set off. when this happens, try unpluging the set for a moment and plug it back in. Possibly a internal fault.

Tv suddenly started being blurry with red double images real bad in top half of screen. its a hitachi ultrascan hd about 10 yrs old.


You need the convergence ICs replaced they are soldered in so its very technical , a repair shop will charge between $230 and $400 to replace them. you can try the autofocus or manual adjustments, but probably need the ICs and possibly a few resistors too.
(2)STK392-110 or kit # X480293 comes with 2 ICs and some resistors
