Looking for an online schematic for a samsung HDTV, TXN2668WH.
I'm an electronics hobbyist but don't own any TV tech troubleshooting equipment. Came across a Samsung television with no green in the video. If anyone knows which part to check, I have solder experience and know how to use a volt meter. Nothing loose on chassis, tap around with a pencil, no change in picture. Everything else works fine.

Time for a new HDTV. I don't think that would be a setup configuration setting. It's broken. Chances are, like my Sony Bravia which had the lower right hand corner of the front of the LCD panel fall and hit a sharp object, it cannot be easily fixed. The LCD panels or electronics typically cost more than buying a new one.
You could check for a Factory Authorized Service for Samsung, online, and find a local shop. Here it's Lakes Electronics near Fort Lauderdale - I know because I used to work for them. I also looked up Sony and found a few more. They wanted over $900 for the LCD Panel for a 32" Bravia TV. The TV only cost like $700.00 new.
I did some research and I found this link that will should you the schematic of the LCD technology,It sounds like one of you LCD color ships is not working properly,your TV has 3 ships (BLUE,GREEN,RED)
you can see how it work; http://www.oerlikon.com/ecomaXL/index.php?site=OPTICS_EN_lcd_projector .Whay happening is that due to the high density the lamp this ships tent to wear out and the three major color don't mix properly causing the color discoloration on your picture.You can find the parts you need at DM http://www.discount-merchant.com/?click=52978 (The correct diagnostic can only be made be a tech) I hope this info helps you please keep us posted .
do you have a service manual for this tv because it may be your red drive circuit and you need to trouble shoot it if you don't have a service manual for your tv I will post a link where you can get one plus free online tech support to help you troubleshoot this problem http://servicemanuals.vstore.ca/
I think it's time to search the net for a schematic and a service manual.
The flashing light combination probably represents a special diagnostic code referenced in the manuals, which will save you a great deal of time and frustration.
You can probably also get the meaning of the codes from tech support.
Finally, electronic knowledge without manuals will not help you that much (I am an ex-electronic tech, now computer engineer too), because the entire TV is controlled by software.
There are tons of secret codes and key sequences (from the remote) which factory repair technicians can use to diagnose or tweak the machine, including color balance, video and format parameters, reseting usage timers, clearing error codes ... etc.
There may also be an USB port for diagnosing the TV via a computer with custom software.
I am afraid that without a service manual, basic voltage and continuity checks are the limits of your investigation.
I have the same TV and the same problem, I take out the block of colours red, green and blue (the blue colour is broken) and I went to the electronic supplies for ask the price and they don't sell just the little blue mirror (blue pixel), they sell all block for $2,050.00 dollars. It's the price for a new one
