You need to check the color wheel on the circuit board if it is integrated then need to replace the circuit board as this issue is with the color wheel and after replacing the the new Cooling fan was able to work and keep it cool but the issue was still there.

try replacing the Color wheel now or the circuit board

Check Fan No. 2 Error Message


The DMD board you installed is bad. It senses the detection line from the fan and generates the error code. Try installing the old DMD board.

TV MAKES A HUMMING NOICE WHEN TV IS ON, WHEN TOUCHING THE BACK OF TV WHERE NOISE COMING FROM IT IS VERY HOT. IT WILL THEN GET LOUDER AND EVENTUALLY CUT OFF TV. TV WILL COME BACK ON AFTER IT COOLS OFF. WHAT...


It is either the color wheel or a fan. To isolate the color wheel, remove the back cover and make sure you put the lamp door back on so that the door interlock switch is activated. Turn the set on and get the picture and humming noise going. Just to left of the rear fan there are some wires. One is a really flat brown or rust colored ribbon cable that plugs in to a board on the left of the wires. This is the color wheel ribbon. When you unplug it the set will keep going for a moment or two but if the noise stops, you will know it is the color wheel. Don't be alarmed because the set shuts off with this ribbon disconnected. Just let all the fans stop (for proper cooling) and then unplug the set for 5-10 minutes. If the humming did not stop you have a bad fan motor. Plug the little ribbon back in while you have the set uplugged. Plug the set back in and turn it back on and try to isolate which fan it is, if it is a fan. If you determine it is a color wheel, the light engine will have to be replaced as Toshiba does not offer just the color wheel. If it is a fan, those can be replaced. I hope this helps. Let me know what you find and thanks for using fixya.

Tv makes a noise


This is definitely the color wheel. It is not the same thing as the cooling fans. The color wheel is buried; even if you took the back off the set you cannot even see it. It's a pretty pricey repair.

That's probably the Color Wheel you are hearing. When you turn the set on the color wheel has to run, one of the several things that has to happen for the set to come on. The color wheel sends a signal back to the control circuit to tell it it's running. If these sets fail to light the lamp they will shut off and try again, that's why you hear the color wheel start then wind down then start again. The set should try three times before it decides it's not going to be able to turn on.

One way you can tell the difference in the fan sound and color wheel sound is if you can get the set on, let it run for a little while so it gets warm, then when you turn it off the color wheel will start winding down but the fans will continue to run for a minute or two.

Samsung HLP4663W color wheel replacement


When I removed the jumper wire the screen color problems I experienced after changing the color wheel were fixed completely. I did not need to reset the CCA values (which came with my color wheel, on a separate sticker). If you have a black bracket blocking access to the jumper wire, as I did, you can access the jumper wire by removing the fan shown just to the left of the yellow and white sticker; there are two screws attaching the fan to the chassis below it. Next, remove the two screws that hold the silver clamshell (the housing for the circuit board) halves together. These screws are right behind where the fan just was, on either side of the protruding fins. They each have a spring under the screw head. You can then pull the visible half of the silver housing forward (with the bracket attached). You will then have access to the entire circuit board. Look for CN810 - it is located right behind where that bracket just was when it was all put together. Pull the tiny black plastic part (that has the jumper wire) off of the pins. Then reassemble the housing and put the fan back on.
