Screen turns blue on my sony KP-51WS500

Common issue on this set--locate the master screen / focus block and lower the BLUE screen control until the blue cast is gone, only a slight adjustment will be needed.

I have a sony KP-65WS500 Ztv turns on but screen is blue with lines. I can hear sound but cant get tv on.the red light blinks five times.. Does anyone know what is the problem?

Can you confirm the actual model number of this set? Some had issues with the picture tubes being bad but depending on model number there may be a fairly easy way to adjust around this to correct the issue.

Sony KP-65WS500 Rear Projection TV About a week ago the left side of the screen started to a slight blue halo over faces, hands, and some of the white letters were light yellow. I adjusted the convergence...

Thats a convergence failure issue. The Sony Type 1 convergence repair kit available from is the kit your model uses. The kit contains the parts and the CD with instructions.

hello High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

Kp-65w500 green flash... led blinks 8 times

I am going to guess that model number is actually KP-65ws500

This is one of group of Sony sets that had bad picture tubes---red, green, blue----the tubes are no longer available and can only be obtained by removing the bad one and sending it out for rebuild (very expensive)

There is one easy thing you may be able to do to correct this problem---It involves no replacement of parts and is just adjusting the Green screen control---usually if this is the case when set comes on background will be somewhat (in your case) green---best way to see this is turn set on and have it on a unused video input---if screen appears somewhat green and has curved retrace lines--you may be able to turn the Green screen control down and continue to use the set---set will shut down if any of the 3 picture tubes pulls too much current--ie--goes to bright green, red or blue.

Let me know if you want to know how to attempt this

Horizontal blue lines with a slight blue wash in the screen

Its because of Over Voltage of Screen (G2) to Blue CRT.
Take off front lower cover (speaker grill) and unscrew board. There you will need to find Focus Block mounted having 6 control knobs. 3 knobs are for Focus control and 3 are for Screen volts control. Find Blue Screen control knob and turn is Counter Click Wise slightly until bluish shade disappear on screen including few blue horizontal lines.
If you select AV input to adjust that will be fine as you do not need to wait for dark-scene.
