Question about Sony KP-51HW40 51" Rear Projection Television

1 Answer

Enhancing picture quality

Hi, I have an older Sony (2000 or 2001) KP series 52" projection television. Lately the picture seems not as sharp as is used to be. Would there be a utility that I could run that would enhance the picture quality? We had a support contract that expired and a technician would come out and focus the picture a bit. Is there something that I could do myself?

Many thanks,

    Thank you for the advice. But, I the Sony technician would use a remote controll device that would form a grid on the screen and align the pictures focus that way -sort of the same way that one would align a printers heads.

    Someone mentioned that it would be called "convergence." I am not sure if that is the correct terminology and if it is how to do it on my own? Would appreciate any more advice.

You might try taking the screen panel off, taking care to look for attached connectors. Make sure unit is unplugged before attempting this. Use a good glass cleaner to clean off all three projection lens assemblies. Do not attempt to adjust these lens, just clean them. Also clean the reflecting mirror at rear and inside surface of the screen. This should improve brightness and focus if they were soiled with dust
