Question about Hitachi 50SBX70B 50" Rear Projection Television
My 10yr old 50SBX70B flickers and cuts out after a short ON period. Changing outlets turns the unit back on for short period then repeats pattern. Suspect power supply and told its repair could amount to $450. Would it be worth it? Its a great TV when workung.
Yes it could cost as much as $450.00.Your set Needs Both of the STKs replaced. Hope you can solder or get someone who can, STKs are convergence ics they also control power too! If you have in your set STK392-110s use the 180s 110s do not hold up They will be big black ICs
