Heard a loup pop when I turned the tv on; the timer/lamp/standby/temp lights on the power on button are now flashing; when I pushed the power button again the lamp light on the power button flashes and there's a clanky type noise coming from the tv like something is spinning and hitting something else

Possible lamp or color wheel---remove the lamp and look to see it is not shattered inside.

Two things to look at---------the lamp to see if shattered inside AND with it removed look where it faces at the color wheel--see attached photo.

Look to see if any segments are broken, missing etc. Many of the wheels fail in this way and some will have a high pitched or even fan like sound before they fail.

Some when really bad will make a grinding noise also. The set monitors the speed of the wheel and if it slows or stops the set will almost instantly turn the lamp off(if possible watch from area where lamp is to see if at turn on to see if it for a moment lights or not.

Remove lamp and inspect the color wheel to see if missing pieces or shattered---it will also just before failing give a high pitched or fan like sound and if running too slow or not at all instant shutdown happens.

Its also possible if you bought a GENERIC bulb--and used original cartridge the new lamp is bad.

This set with Akai is actually made by Samsung (they own and use the Akai name).

If lamp light etc and you have heard a cracking sound it may be the color wheel.

You can remove the lamp and look where it faces--look and the wheel can be seen----is it shattered or missing plastic pieces?

The wheel commonly fails in this fashion and is turning at over 12,000 rpm. The set will detect if the wheel is stopped or moving too slow and just what you describe will happen.

Wheel is widely available and You Tube has video instructions for replacing them by model number.

Questions?

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.

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

you need to reset the lamp timer, usually done by holding some buttons while turning on

replace the lamp.

what i would do is crack into the tv and watch the individual parts being careful not to unplug anything while you take the back panel off.....turn it on and see what happens. let me know what happens
