My TV picture disappears and the audio disappears for a couple of minutes then it comes back.
The green power light stays on the whole time. The lamp light does not turn red.
What could be the problem?

A crt board can cost from $25 to $40, the problem is that crt board should be tested before replacement, even if it is the most likely cause, there is always possibility that there is also something else (tube, main pcb etc.)

Picture shows only red on the screen

We had a problem with our Panasonic projection TV once that showed this symptom. We had to have the red CRT (cathode ray tube) replaced in our case -- it was under warranty at the time, but was a fairly expensive part. It could also be a bad board driving this CRT or a loose connection between the two. If you have it under warranty (I'm guessing not) have a repairman diagnose, otherwise, it may be time to replace with a nice LED flatscreen...

I have a ws-55819 that leaked fluid onto the green signal/control board. How do I replace this board and do I need to replace the picture tube?


If your green crt is leaking you will need to replace it. This is fairly expensive and if the unit is older you should really replace all the crts or you may have a problem trying to balance the color.

CRT projection units are run very hard and need a coolant in front of the phosphors to keep the tube from overheating and imploding. There is about 1 inch of a special optical coolant sandwiched between the phosphor panel and the outer panel. It is sealed at the factory and never needs changed or added to unless, as you have, experience a leak. I doubt that the leak can be fixed successfully. That means replacement is your only option.

If you want to proceed I have a tip at which will walk you through it and also give you the best place to get the part at the best price.

Thanks for using FixYa and for the great rating.

My screen has no red color. I assume the red color gun has gone bad. Is this it? How expensive to fix? Is there a do it yourself cheap fix?

Its most likely a problem with the Red CRT drive board. If the tube were to fail you would have either a red screen with lines, or the set would shut down. Often its as simple as a bad solder joint on the CRT socket on the Drive Board. I would check the board very carefully for signs of bad solder such as dull ( Indicating Cold solder ) or actual cracks in the solder. If all solder looks good I would try replaceing the Drive board.

It probably is see if you can align the convergence manually or auto if available, you can order just the convergence ic's or the convergence amp board, whichever you prefer. check pricing and availability. also check Blue crt for faded picture, usually dirty crt fluid, makes picture dark and discoloured. If it is you may need to replace the blue crt also. this gets a little expensive, again check pricing hope this gets you started RFT

Sony kp57hw40 52 in. televison

This can be caused by a problem within the "D" board or a bad CRT. If the D board can be fixed, that would be the least expensive repair. Even so, this will require a service tech. Depending on the cost of an estimate, you could call a service tech and explain that the TV may need a "D board" and try to get it serviced. If the D board replacement does not fix the problem, the CRT would be next. Maybe the service tech would allow you to pay a small fee for the experiment and a fixed service cost if it is the D board.
