No picture Toshiba Projection Colour TV Mod 42PW33P Has had red shadowing now picture gone

Try to unplugged TV from outlet for 2 min and pluged back.

I am sorry to say that it is a highly specialised job, re converging these so Yes you do need to call an authorised Toshiba Repairer.
Hope that answers your question.

Hi

this means you need to replace the resistor or you need to replace the convergence correction amplifier IC...

Thanks!

stk 392-110 ic's on convergence board are likely problem.
from rear, board is at bottom right. I usually replace all but they are marked by colour.

Sounds like a convergence issue with your RGB colour channels - probably need to get it serviced and have the convergence tuned.
Unlikely you can do this yourself.

change your convergence ICs that should solve your problem.If you need more info let me know.

Hi,

The model number 42pw33p is not a valid Toshiba model number. However, 42H81 is a valid number. The listing below is for model 42H81 ONLY! Double check you number before purchasing.

There are 3 screens that make up the screen assembly The inner screen is the Fresnal Screen. The middle screen is the Lenticular Screen and the outer screen is the Protective Screen. Please click on the links below to purchase these items.
