Question about Samsung HCN4226W 42" Rear Projection HDTV-Ready Television

1 Answer

Samsung DLP TV- colors seem to mess up -Faces have green streaks

Our 2 year old Samsung HL-R4266W works fine for couple hours then does really wierd color shading. At first we have some green shading on the skin tones, then maybe bright gold or yellow coloring of whole picture. It does it playing DVD also. We can turn it off for 5-10 minutes and it will usally be OK for  a little while.


Whats the matter with it?

Samsung HLS5087W picture keeps turning off. Sometimes it happens after a couple of hours and then every 10 minutes after that. recently changed both bulb and color wheel. Tv only 6 years old.

I would first check the lamp is properly seated and was it a Samsung or a generic brand? Also not indicated is does sound remain or not.

Replaced the color wheel on a Samsung DLP

Did you replace the color wheel yourself ? Sometimes you have to remove a small black jumper on the DM module on the light engine and that will remove the greenish but sometimes adjustments also need to be made in the service menu.

The green is taking over all the color on the tv

March 14, 2009

I have the same TV which had the same issue ( green in picture ) - back on 10/2007. I called Sony. They had their technician replace the optical box ( factory defect ). There was no charge for the repair even though TV was out of first year of warranty. Call Sony.

Samsung DLP sound or picture. TV is completely dead

Assuming the noise is a high-pitched whine, then yes, it is the color wheel.  If the color wheel goes out, the TV will turn on for a while, then turn off when it can't establish color wheel sync.  The color wheel has to be in sync with the mirrors on the DLP, so if sync can't be established, the TV turns off.
You can order a new color wheel from Sears or (among other places) and replace it yourself, if you are so inclined.

Samsung hlr4266wx dlp tv shuts off

This tv usually if detects a fault will display via leds a error flash code. Refer to Owners manual for What the codes are for. If you go to Samsung Website Copy and paste link for manual.

Problem may be lamp is failing or ballast which operates lamp may be Bad. Could also be Temperature fault from Inoperable fan or Color wheel. Bulb of course is first choice of possible problem followed by color wheel then ballast. Color wheels usually will start making bearing noise when they start to fail. Hope this helps.
