SOURCE: Loss Sync

According to SharpUSA the problem with the "Loss of Sync" error message is that (most probably) the cables (between the box and the display) are not connected properly (so remove and reconnect them carefully, on both units) or a cable is defective. 

Also, after you reconnect the cables try turning on the unit, if no success then depress the "clear" button on the external box (under the door on the front and on the bottom left and try turning on the TV again). 

It is, most likely, that the cables are not seated properly. Reseat the cables on both the display and the external box. 

Hopefully, this will clear the problem
if still does not solves your problem just replace all the cables connected between .u can get the new cables at radioshack web site.just place an order they will provide you. thanks.

Loss sync


The T con board is defective. That board has a metal cover on it and 2 wide flat ribbon cables going to the bottom of the screen. Replace that board and you'll have a perfect picture again.

My protron 19" tv works


I suspect the Sync is on the blue colour and the tv is expecting that, if it is S-Video. The device supplying the picture is not set up to supply that. Check what system the tv requires and set the video source accordingly.

Poor picture no color


OUCH! LARGE DARK SPOT IN CENTER IS NOT GOOD FOR PROJECTION TV. YOU BURNT THE TUBES. THE LOSS OF COLOR IS THE ROOT CAUSE SOUNDS LIKE A DEFLECTION CIRCUIT PROBLEM. THE TIMING FEEDBACK IS USED TO SYNC THE COLOR CIRCUIT. IF THE TUBES LIGHT WITHOUT DEFLECTION THEY BURN THE CENTER PHOSPHOR COATING INSIDE.

Picture rolling when I first turn on my tv


A rolling picture or loss of vertical sync can be caused by several components including a bad signal board or jack panel assy. You will not be able to resolve this yourself. contact a Mitsubishi authorized service center.

Some chanels the picture star to go out of sinc. Is any thing inside to control this problem?


Loss of vertical sync. Could be a leaky sync IC. This is a computer chip problem. Either the chip is bad, or its power supply is too low. There is not much you can do to fix it yourself, sorry.

SAMSUNG PCL5415


If the sound on your DLP TV is out of sync with your picture and the TV is not connected to a home theater system, a Samsung technician can adjust the sound sync function on the TV so that the sound and picture are in sync.
To arrange a service call to adjust the sound sync function, call Samsung Customer Care at 1-800-SAMSUNG (1-800-726-7864).
