Bought a second hand Samsung hl-p4663w. Worked for two days then all of a sudden, there is sound but no picture. I can see the bulb lit in the back of the TV. TV responds to remote control commands like volume, channel and on/off. On power up, the menu on front cycles up, pauses at lamp, then no lights are displayed. Nothing blinking. Thanks for any help.
i have the exact same issue.
have you found the cause?

The most common blink code for the Standby/Temp LED is the Temp Sensor and or Actuator Board. You can confirm which on by jumping the CN106 connector on the Actuator board. If the set works now, the Temp Sensor must be replaced. If it doesn't work, the Actuator Board would need to be replaced. If you are not familiar with the chassis or electronics at all , I do not recommend trying to fix it, call a professional. Don't take the chance of damaging it further.
I hope this helps,

Listen closely. The tv should make a high pitch whine as it turns on. If it does wait and see if it tries this a few times. If yes then check the bulb, I have seen cases where the lamp shoves the power connector back into the set. If the tv starts with a grown or heavy vibration noise, then your color wheel may have broken and needs replaced.
