Question about RCA D52W20 52" Rear Projection HDTV-Ready Television
My top picture on my tv is concaved. There are no picture controls to adjust does anyone have an idea how to resolve it?
I have the same problem also. The peoples heads are cut off! Need help on what to do.
Check the horizontal frequency and the electrolytic filters used in it. damm sure there must be filter that make it look like a concave. also check it by decreasing the width from the service mannual of processor. there is a service switch for every processor. that is his internal control unit. may be it is from the processor adjustment. you can set it by increasing or decreasing the frequency or display width-height clock pulse from the processor. to know about that perticular switch you must concern to the company....
