Samsung rear projection tv st47w3p picture dims after few minutes

I have a samsung 47" rear projection tv when I turn it on everything is fine for few minutes and than picture starts to dim kind of fade out really dark. Still can see it but it is extreamlly dim. After turning it off for a while and back on it is ok just for few minutes and does the same thing again.
Could it be the power suppy or what can cause this it seems to me that it is a heat issue with some of the componands on the circuit board what can cause this? If you can help I do appriciate your support trying to see if it will be worth spending any inflated cost or go for a new tv. this set is about 3 years old.
Thanks

The green CRT may be intermittently bad or the focus screen block. Certain sony's are common to have bad CRT's. When the screen goes green does the set shut off?

I think it could be a faulty diode on the power supply board. If you can check this for yourself otherwise call out a competant technician. Good luck.

Its the lamp that needs replacing. It will run for a couple of seconds and then it would dim or turn off.

The more you play set the longer it will last, it sounds like you may have poor connections, cold solder joints try soldering around flyback transformer.

Rear Projection TV Picture is all green with Horizontal Lines


It looks like you started out with an intermittent solder connection which may have been fairly easy to find early on. Now, unless a technican can make it come and go while tapping on the circuit board and repair the connection, it may be a very expensive shop repair.
