I have a samsung hc-p4752w rear projection

The power light comes on but when you hit it, it sounds like it is trying to turn on but nothing shows up on the screen. Is this a simple fix, or a common problem?
thanks

look for trouble in the low voltage and or high voltage power supply circuits. the popping sound could be an exploded safety capacitor in the horizontal output to the flyback transformer. the horizontal output transistor maybe damaged. chances are the low voltage regulator is also damaged.

I think you have a fault on the chroma board and on the picture frame board. If you can trace it yourself try these two locations otherwise call out a competant technician. hope this helps.
