Check your CRT boards on the end of the tubes for burn spots, and burnt components, check the resistors to make sure they are not shorted, burnt, and they read the correct resistance. Check the diodes to make sure they conduct in one direction only and are not shorted or open.

Sounds like the projection bulb is heating up then it shuts off for safety reasons. If you can locate the bulb, there is most likely a screen (wire mesh) that traps dust when the fan is on to cool the bulb. Try cleaning this screen and see if it helps. It could be already too late and you might have to replace the bulb.

Hi Misty,
I would reset or zero out all the colour/ contrast settings first.
You can access all these via the menu on the remote.
If the reds still seem a bit weak, you can purchase new lamps on the internet. Depending on how old the TV is, a new LED flat screen might be the go. The picture difference from rear projection to LED panel is significant.
I would strongly suggest you do not replace the lamp yourself, there are dangerous voltages inside the TV cabinet.
Also, if one lamp is weak there is a good chance the others will fail soon. If it has done more than 5000 hours, time for a new TV.

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.

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.

it could be either the blue CRT being bad since the set shut down after turning blue. It could also be the convergence needs replacement. The CRT sounds more likely you can get the replacement Blue CRT and also the sony #1 convergence repair kit from www.tvrepairworld.com they can also assist to determine which of the two is most likely causing the issue.

This is one of a group of sets that had bad picture tubes; the set uses a red, green, and blue tube.

The tubes are no longer available from Sony.

There is something simple you can do: it requires removing entire front grill on front of set beneath the screen (two or three screws on back on either side.)

Behind it is an inspection plate and with that removed look for a black plastic block with 6 small adjustable shafts. Three are marked focus (do not touch those) and three are marked screen; they are marked but not easy to read---green is the middle in each row left to right.

You want to carefully locate the BLUE SCREEN control and with the set on turn it down until the blue screen just goes away, this is usually best done with the set on an unused video input, all you should see is video 1 etc, just adjust down until no blue is seen.

It has to be done with the set on and DONOT put your hands inside the set, I use a insulated screwdriver or plastic tool for this.

If this corrects the problem you may only be buying some more life from the set. I changed dozens of these when they were under warranty by Sony.

Before you rate this solution let me know if you have questions.

The Blue CRT has shorted which is shutting the set down. Replaceing the Blue CRT should solve the issue. You can get a replacement Blue CRT for the WS500 from www.tvrepairworld.com

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