Question about Sony KP-65WS500 65" Rear Projection Television
I am trying to repair my Sony tv and not having very much luck. I turn it on and it has a clear picture but after about 30 seconds it fades to a solid blue screen with a darker blue arch coming down from the top of the screen and a darker blue arch coming up from the bottom. I opened up the back and watched as this happened. When the tv turns on all 3 colors light up but after 30 seconds the red and green fade down to almost nothing. I have some electronics training but none on tv's. I do know how to solder if any components need to be replaced. Does anybody have any suggetions? Thanks
I just fixed mine. I read other posts that suggested this and it worked. On the front of the set at the bottom of the speaker cover are 2 caps, one on each side. Remove those caps to find 2 screws, remove screws and then remove that cover. Behind that is a panel with 4 screws and remove it. You will see a box with 6 knobs, 3 on top 3 on the bottom. Top are focus and bottoms are voltage to each lamp. Blue lamp is left screw, green lanp is middle screw and red lamp is right screw. Counter clockwise lowers voltage(very small adjustments. So if your screen is turning blue turn the left screw just a littleat a time. I also had red and blue lines on my screen so i turned them a little as well and they are gone. Give that a try, it worked for me.
