Question about Samsung Televison & Video

1 Answer

No green in picture

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.

When I turn the tv on, it blinks green then a steady green but no picture. When (if) it does come on, the picture is perfect. The tv is only four years old.

You have capacitors in the power supply that need replaced. If your not electronically inclined then I would have a tech take care of it for you. It's not an expensive procedure.

Halfof the picture is green

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 think it's time to search the net for a schematic and a service

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.
