Sony kp-51ws510 Rear Projection HDTV - Picture quality is fine, just doesn't have any red's in the picture. What shoud i look into?


Make sure the cable box or DVD/Blu Ray player is hooked up properly. Sometimes one of the component cables can become loose and lose the reds.

The red tube could be shot also. My old projection tv had the green go out. Believe it or not the whole thing can be replaced, but to replace a CRT on an older model can cost a lot.

My sony kp-51ws510 screen is red when turned on


This is one of a group of sets that had BAD picture tubes--all of them.


At one point the tubes were all being replaced under warranty for the first two years. Now the tubes are only available on a rebuild basis and very expensive--defective one has to be removed and sent out for this.

If the set goes bright red in your case it is the red tube and the set is shutting down as the set detects way too much current is being drawn by this.

There is a way to TRY to adjust to compensate for this that requires no replacing of any parts. Essentially what it involves is getting at the point of adjustment from the front of the set.

If you are interested in the instructions reply to this posting and I will be happy to post them here for you----no soldering or replacement of parts is involved and you will know in fifteen minutes if it will help you or not.

I have been fixing sets for well over 30 years and have done this adjustment several times---it may if it works just buy you some more life out of the set as ALL three tubes eventually have this trouble.


Let me know if you want the instructions and I will provide them here.

when it goes green, your green picture tube is shorting out, replaceing the green tube costs alot of money. these sony's had alot of bad tubes, the red and blue are probably going out too, it will cost alot to fix this, at least $500 even if you find good used picture tubes to put in it.

No Picture / TV screen RED


There seems to be a dry solder joint on the video amplifier IC. The red picture is cause by a defective video amplifier IC(IC701) that is located on the red CRT assembly.
This repair might not be a DIY due to the danger of working around devices that produce high voltages in excess of 32KV.
Let me know if you need further assistance.

Screen went blurry 20 minutes later no picture no sound just red flashing light on front


These sets had bad welds in the gun assemblies of the picture tubes. Now, one of the tubes has failed (shorted) and the cost would be too high to replace all three.

Red Shadow


UNDER THE FRONT DOOR PRESS THE BOTTOM BUTTON "FLASH FOCUS" AND SEE IF IT FIXES IT. IF NOT AND YOU SEEN RED DOUBLE OF THE IMAGE, THEN THE SET PROBABLY NEEDS THE CONVERGENCE CIRCUIT REPAIRED.
