Access service menu for Samsung

Apparently I was in denial about the color wheel. With my son's help, I pretty much confirmed that it was NOT the fan. I could have replaced the fan after pulling the boards out to do the color wheel, but didn't want to shoot myself in the foot. I had my son hold the lamp saftey switch so we could turn the set on with the lamp access panel off. Then after the buzzing started, I VERY, VERY carefully reached in & touched each of the 2 fans to see if the pitch of buzzing changed, or if the fans were vibrating at the same frequency as the buzzing noise. It did not change one iota. So I went with an educated assumption that it was in fact the color wheel (just like all the posts in the threads had said). Our set was born in 10/04, and the color wheel was much easier to do than the one in the excellent step by step post that I found elsewhere. The procedure for accessing the fan (if the need be) is basically the same as the colorwheel replacement procedure, as far as removing panels & boards, etc, and gaining access to the fan (you can't do it just thru the lamp access panel). It took me & my son about 2 hrs (including the fact that we forgot to reinstall the colorwheel hood/shroud the first time we reassembled). We also didn't have that jumper to deal with either. HOWEVER, while the picture looks great for the most part, I think I may have to use the service menu to set the color levels correctly. The problem being with the black levels I think, because in a dark scene in a movie, shadows look blotchy, almost rainbowy in a somewhat pixelated sort of way. The new colorwheel came with a little sticker with the new CCA color setting values as well, but in researching the service menu access codes, I read one post where someone said that simply accessing the service menu (even if it's just to see how many hours you have on your lamp, without even changing any settings), will reset all your settings. I don't know if this is a problem for me, as I never changed the settings before, and never had it serviced by anyone else.

Most TV's have a back menu for service people to use. Since I don't know what brand and model you have I can't tell you how to access your service menu but the procedure is usually pretty easy and doing a search with your model and "service menu" should give you the particulars.

The speed of the color wheel needs to adjusted or the CCA values. Both are found in the service menu . If you paid a company to fix the TV, call them and tell them that they forgot to perform these alignments. If you did the repair yourself, you'll have to call around for a price to have a Samsung service center perform these adjustments. I don't recommend consumers access the service menus of modern TVs because one wrong button push and you may cause irrepairable changes to the TV's proper operation.

Please contact samsung service center with phone.

Try this:
Access menu service by press on your command, with your TV OFF:

INFO + MENU + MUTE + POWER ON

Then you should get access to Service Menu.

The last item says: RESET

This will do a reset to the TV.

Make no harm.

WARNING: If when on service menu you feel tempted to "screw" on anything FIRST take note on ALL you change! You can compromise the TV ...

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.
