You do not need to replace the CRTs(picture tubes) just the assembly that is connected to the red CRT, or just the IC7101, with markings TDA6120Q.
I would suggest to put fresh solder on the IC leads first since the TV only becames red after is ON for a short while.

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.

The picture is is now in pink


If Sony KP-51ws510 it is an common issue with the picture tubes but there may be a simple way to adjust something in the set to correct this--these had problems with the 3 picture tubes where it can go to excessive red, green or blue.

Confirm model and issue and I will assist.

It only requires a screwdriver and the back does not have to be removed in this case.

On our Sony KP-51WS510 projector television (with HD cable box) when we turn it on the screen goes green and the turns the cable box off and goes blank. Also I noticed the light on the front of the...


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.

Have a Sony KP-51WS510 with red outlines


In replacing the CRTs, there are multiple focus adjustments. The basic one first is the Mechanical lens adjustment on the CRTs, (in this case red), the second one is the Electronic Focus on the Screen/Focus Block on the front of the unit behind the front panel. The third focus and on of the most important is the Beam Centering Focus. (In this case RED CTR) It is located on the neck of the CRTs. They are the first set of adjustment rings up from the CRT Boards. If any of these focus adjustments are off they will cause a symptom like yours to occur. Normally these adjustments are made before any convergence adjustments are made. I would double check to see if the repairman made these adjustments.
I hope this helps

I would suggest to turn the screen control potentiometer down a bit, this control is found on the front of your TV nearby the CRTs.
The part looks similar to the picture. Click here to see picture.
The red control is the one on the left if you are facing it.
Let me know if you need further assistance.

These sets have been known to have loose welds in the picture tubes. Most likely your tubes are showing this problem.

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.
