When you turn it on, the green LAMP light goes on, then it clicks and the STANDBY/TEMP red light goes on, then clicks and back to the green LAMP light. It does this a few times, then The TIMER green light goes on and the all blink together and nothing happens. The bulb was replaced within the last 8 months. It worked the night before fine. Per the back of the TV it was manufactured in Nov 2005. Is this typical for only 5 years?

green green is power on, normal
then it tries to light the lamp, but it can't so the protection circuit comes activated.
you get red and green blinking

Then it goes to standby, red and off.

so something has happened to the lamp, or lamp ballast power supply.
Take the lamp out and check if all is OK with the 2 terminals in the connector, and the leads to the lamp are intact.

Failing that, I would suspect the ballast lamp power unit

READY light is green when the projector is ready to be switched on
LAMP is dim when the projector is ON, but goes bright when it reverts to STANDBY.

Check that the lamp cover is fully down and the cover switch is activated

Samsungs problem child, if the lamp is ok, then the best thing is to have a good tv shop inspect it, last three we had where not repairable, needed DMD, Digital board, cost more than tv was worth.

I think it's capacitor issue on the power supply board. open it, look for power supply board and fine bloated capacitor and replace it.

Check your color wheel. There is a DIY guide for replacing the color wheel. Mine did the same thing yours is and my color wheel was all busted up. Unfortunately after replacing the color wheel my set continues to do the same thing, but this could mean I need to replace the ballast as well.

The color wheel needs replacing. Thats causing the whining and it will also make the lamp light blink.

If the lamp has been replaced I would think the Lamp ballast would be most likliest followed by the color wheel and then the Digital board. You can get any part needed for your model at www.tvrepairworld.com just leave them a email they respond quickly.

you need to test the lamp with a ohm meter, to see if its working correctly

power pack capacitors have failed they will need to be replaced with new ones and that should repair the tv, soldering skill is required to do this or replacement of the entire power pack.
hope this helps

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
