look for bulged capacitors and replace them. Amazpn has a guy who sells kits of cpacitors for most TVs and Displays, but a local electronics parts house is cheaper and faster. Make sure you get 105 degree Celsius capacitors.

Our Samsung HPN5039x Plasma TV isn't turning on: when we press the power button, the red power light flashes then turns off. What do we do?

Hello, It sounds like you have a defective power supply. Typically, +5 volt stby is present if the TV switches on with front indicator light. On the power supply, connector 802 pin 4 is the on command from the pcb main to switch the on. If this signal is present but still no VS,VA,VE panel voltages are missing, the p. supply is bad. Good luck!

Replaced color wheel and the still. Cycles on and off..with "lamp" green light flashing along with standby light flashing...nothing on screen and lamp not coming on? Its an hlp5063w. Please...

Since you have replaced the lamp and wheel, next would be the ballast and power supply board. These provide power to the lamp and Samsung recommends replacing both at the same time. If power supply board is bad, it can destroy the ballast so replace both. This usually takes care of the problem.

My tv is a samsung rearprojection and every time i switch it on it gose strate to standby

The first place to start will be the Main power supply. Any time the set shuts down and goes to standby is a symptom of a bad power supply. I recommend replacing the power supply unless you are skilled in component level repair.

PSU problem

The most likely problem is something dragging down the power. There could be a problem within the power supply as well. This is a "switch mode" power supply. That means that if the primary side does not oscillate correctly, you will get this cycling as well. These are hard to diagnose remotely. Typical power problems such as this run about $15 or so for parts plus the local labor rate if it is within the power supply. The parts cost will rise to the $30-$50 range if the output amp section is the problem.
