Question about Sony KP-53V45 53" Rear Projection Television

1 Answer

Sony KP53V45 53 inch

The tv was manufactured in 1997, worked great until recently. The picture now goes off and on constantly. Has a blue screen when it flips off. Usually lasts about 10 to 20 seconds at a time. Ideas?

    Purchased the Sony 53 " screen in 2000. Worked fine until recently. The timer lights comes on and the screen goes dark, however the audio is fine.

    When turning on the power, the picture goes on and off for a numer of minutes then stays on. No problem with the audio.

Two three-pin voltage regulators near the left side (looking in from the back) bend over from the heat and short to a ground rail. Check and straighten them with the power off and the unit unplugged

tv has a blanking picture mute circuit. adjust the screen controls which are located behind the speaker grill in front of set. there will be a access panel to unscrew in center and then you will see a black 4 inch square box with 6 physical knobs. 3 control screen the other 3 controls focus for red, green, blue. turn them down and slowly start turning them up. fixed.

Yellow haze and no picture


sounds like you have a bad optical block, very costly but the manufacture of these is LG and they have a recall program on certain problems is this model you may want to give them a call and see if yours might be covered.

Sony 57 Inch XBR 2001


I don't have the XBR, but on my sony, using the cable box remote, I had to go into menu/display/etc. and mark the 1080i, 720p, and 480i settings. you usually get a "if you can see this" comment if your tv accepts the settings. for standard tv i set the screen to normal, and when the upper channels go to HD, they auto go to full screen. Sounds like you are using the component cable, and also make sure you are on the video port of remote, and the the TV input. The above worked for mine. Hope it helps.

Blue Screen and TV shuts off


Yes, you are correct on the phrasing. The CRT's were a common issue with these units and all three must be replaced as sooner or later the green will follow the other two CRT's. It was a great model and had a beautiful picture when operating normally. The CRT's are costing about 200 each for rebuild as the green and blue are mostly no longer available. Your repair cost are going to approach $1000.00 or more.
