press MENU button on TV set.

this may be due to a stuck on mode select button control, are you going to try to repair yourself ? do you have a shop manual ? let me know

try plugging it in.

Yes the convergence ICs need to be replaced, however so dont the six 1.8 ohm 1watt resistors as Toshiba recomends replacing those six resistors when the ICs are changed. You can get the 50H71 / 50H82 Convergence repair kit as the 42H83 is identical to the 50H71 series, so the kit will work for your model. Heres the link where you can get the kit.

I just got finished repairing the same model . The convergence modules are bad cost of repair is 250.00 for a service center to fix. My advice would be call your local service center tell them what i told you bad convergence ic and ask them how much they charge,


thanks doctor video good luck since 1987

Hi you have bad convergence ic stk modules ,Cost for repair center to fix is 250.00. call your local repair center ask there prices on convergence ic repair. It is a very common problem every 3 to 5 years .Our service center does a lot of these.


thanks doctor video 1987

It is common problem in this unit. Toshibia has a service bulliteen to service shops about this unit. It involves replaceing 11 16microfared surface mounted capacitors on the cuircit board known as :HYPERMODULE. I am currently got one of these in front of me now at the shop and the repair is rather difficult .,, removeing the board take alot and then repair the board take some doing ... you must be an expert at soldering surface mount components, i would not recomend this for a non tech. but on the good side your set is repairable.

Replace STK convergence IC's w/OEM or better parts.Senior tech soldering ability needed. Ex==Steel jumper wires feeding b+ to conv. IC's need resolder to prevent call-back.Also, best re-alignment done in service mode==consult service literature.

Most projects in life are "easy",if you know how.Chassis will have to be pulled,convergence IC's replaced w/top quality parts to prevent recall.Some excellant soldering will be needed for prevent maintenance,for instance,the steel jumper wires feedig b+ to convergence IC's. RE-align in servicer mode==final step.
