My sony KP-65WS500 had a bad red picture tube. So

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.

An issue dealing with the red picture tube but usually a simple adjustment of the screen control inside the set will correct this problem.

The 8 blinks means its a High Voltage error which mean ur D- board is bad it'll be T8005.

Red and Blue Tube screen drive controls needs to be turned down some, tubes are over driving causeing drive lines.

power light if it shuts down should blink a error code--count the blinks and a pause?

CRT bias tracking off kilter.

your tv is protecting itself ( please be very carefull becouse you are dealing with very high voltage aprox. 28000 or more volts its deadly my advise is to take it to your service center

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

Here is the part number for the blue tube B 07MVC61, the Red is R 07MVC61, and the Green is G 07MVC21. The number to contact the company that makes the tubes is 1-800-241-5005 Ext 143

Usually that is a sign that your red picture tube is ailing. However there is a chance that it can be adjusted out, at least buy you time worst case.There is a voltage control in the front of the TV, you have to remove the bottom front half of tv to get to it. Some Sony's have 2 screws hiding at the bottom of set in front hidden behind 2 plastic covers,others just have screws along the backside.Be careful there are wires to front panel attached so remove slowly and leave wires on just move it out of your way..Once you remove that there is a small access panel to take off. You will see the voltage control (small plastic square with 6 knobs) The top knobs are focus controls for each tube the bottoms are for voltage adjust. The far right knobs are for red.So you can turn the red voltage control SLOWLY to the left,this will reduce voltage.Reduce until you see the red lines disappear. If you go too far one way or the other with the voltage control the tv will shut down and you'll waste time readjusting and turning set on until it stays on. If you can't adjust it enough to get all the red out without shuting down tv tube is in too bad of shape.
