Check the LVDS cable !!! It is the cable that supplies the video signal from the main board to the LCD controller. If wiggling the cable clears up the problem or invokes the problem, you need a new LVDS cable!

The main board may cause this problem. If it wass happened when you play DVD, so the main board needs replacing.

Hello Ed -

You mentioned a "box" so I assume you're using a cable/satellite receiver or digital converter, I would suggest resetting the receiver/converter. Some can be reset by simply switching off and on, some have a reset button and others need to be disconnected from the power supply for a minute or so. Reset the box, then try the TV again. Sometimes the software/firmware in these boxes can crash and re-booting the box will solve the problem.

If you have a DVD/VCR or game system connected to the TV, you should also test whether have audio on the TV from any of these devices. Finally, if the TV has a headphone socket, try plugging in a set of headphones to check for audio.

If you have audio from another device, the problem is likely to be with the "box" rather than the TV. If you have no audio from any device, try restoring the TV settings to the factory defaults by holding down the EXIT key on the Samsung remote until a message appears on screen saying "Resets all settings to the default values". When this message appears, you will need to confirm you want to continue with the reset. You will lose all user settings for video and audio, so you may want to write these down before you reset.

Finally, there is a firmware upgrade for this TV available from Samsung. Please check your current firmware version before installing the update. Click on the link below for the Samsung download page, then click on "Firmware" in blue text. You will need to download both the Upgrade file and the Upgrade guide, which contains the instructions for installing the upgrade:

http://www.samsung.com/us/support/downloads/LN52A650A1F

If you get as far as installing the upgrade and you are not sure how to do it, please let me know and I will be happy to provide detailed instructions.

If you've done all of the above and you still have no audio from any device or headphones, it's likely that the Main / AV board (motherboard) in the TV has failed and will need to be repaired or replaced.

Hope this helps. Please try the suggestions above, then let me know if you need further assistance. You can reply to me by clicking on "Add a Comment" below your question.

Regards,
BElectric

Syncmaster 912n red tint problem


Hello,

A red or pink tint on LCD monitors indicate that the back light florescent bulbs are about to go out. Just like on regular florescent these bulbs are just much smaller but burn out just the same. Check the date on the back of your monitor, if it is less than 3 years old then its still under warranty but if its not then its time for a new monitor. The bulbs can be replaced but it really is not worth the trouble.

OUR sAMSUNG sYNCMASTER 205BW has a red tint in the background and cannot adjust it out.


Hello,

The red or pink tint indicates that the back light florescent bulbs are failing. These bulbs are just like the bulbs in home and office lamps just much much smaller. When the reach the end of life the light output turns from pure white to red because the bulbs are not fully turning on. Check the manufacturer date on the back of the monitor, if its less than 3 years then the monitor is still under warranty. If its older than 3 years then its time to get a new monitor because your is about to fail.

I hope this helps, if so please rate my solution.
