The screen turns blue after about 2 minutes of turning on the TV


Sony TVs has an Optical Block issue. If there is an issue with the optical block, then there will be green, blue patches or tint on the TV display. Try resetting the TV to the factory settings and try Power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then TV may require service. You can contact the Customer relations team and check for the available options. Sony had repaired free of cost for such issues. Hence, contact the customer relations.

Blue screen


The blue picture tube has gone bad. Sadly they are no longer availible for that unit. But the blue tube assembly can be sent back to a company called Video Display. They rebuild the tube for a very reasonable price. The hitch is that it takes a professional tv tech to reinstall and align the rebuilt tube. Most respectable shops will do this work but the repair is spendy. Usually around $450 to $500 or more.

Screen fades to blue.


The Blue SCREEN setting is too high. These adjustments are located inside the TV behind the front panel. There are two screws behind covers and then a wooden panel to remove to access the adjustments. The leftmost set are for BLUE, the middle are GREEN, and the right are RED. The top row are FOCUS and the bottom are SCREEN. Focus will focus/unfocus the tube and Screen will adjust the power of that tube (there are 3 tubes, one for each color). If Screen is adjusted too high, horizontal lines will appear (my TV had red lines, but I played around with the knobs and saw that it could happen on any of the colors). Additionally, if SCREEN is set even higher than that, the tube could go so high that it turns the whole screen that color (in your case, blue). If this happens the TV will shut down, probably due to either overheating or overvolting. To fix this issue, turn the appropriate SCREEN dial down until the lines go away. In your case, you want to turn the lower left dial down. Don't turn it too far down, if you turn it more than necessary the TV can give you an AKB error (noted by the STANDBY light flashing a sequence of 5 blinks).

My TV Screen turns green or blue after 10 minutes of the tv on


You have a chip that is overheating due to heatsink coumpound being dried up. You need to find that chip and heatsink and apply new compound to both parts.

TV turned off itself


Can you still turn it on?
If so, does it stay on with sound?

If the sound is ok and the picture is blue (even when changing channels, inputs, etc.) the lamp may have gone out.

Can you see the TV menu when you press the menu button on the remote or TV?

Picture comes on then fades to blue


Check the info from this website to see if you are able to fix your TV. You should turn the blue screen control down slightly counterclockwise. If that did not work, then more likely you have a video amplifier IC defective or a blue CRT.

No picture, blue screen only


Good Day;

It sounds like you have a lack of signal; 1. reset TV by unplugging TV & signal sources from wall for at least 5 minutes then plug back in, 2. Turn all eguipment on such as cable box, dvd & etc, then change the inputs from your TV's remote, if still no pix,only blue.

Good Luck.

Sony turns on and off again


My tv too had a blue screen problem. Then it started to shut down after staying on for less than a minute. I thought that I would with a huge repair bill but I followed the directions at this link: http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html and now my tv works perfectly.

Sony KP-51HW40 51 in. Rear Projection turns blue


Hello......
First reduse the G2 voltage for the blue c.r.t,and watch if the unit works for longer period (offcource blue colour will be not present).After reducing G2 voltage to blue c.r.t still behaves the same than c.r.t is faulty and you have to replace.
Pls count the red led blinking when it goes off,incase it goes to std by mode.
