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.

No vertical deflection-need schematic


follow the 2 sets of wires off the yoke. one goes to the horizontal sweep section and the other goes to the vertical. the drive ic with the metal tab is blown.that is what drives the vertical deflection. there is a few capacitors there. 1mf at 160v and .47 at 160 and 2.2mf at 50v on most sylvania sets . if the plastic on the top of the capacitor is shrunk,it is getting hot and is no good.that can cause a loss of sweep or foldover.99% of the time it is the vertical output ic that is gone.

I have vertical shifted up from bottom and foldover from top down


This is caused by a defective capacitor in the vertical circuit. If you can solder, you should be able to fix this your self. Let me know if you wish to attempt the repair and I will supply additional details and instructions.

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.

DS25390 Verticle foldover


If you have a picture but the top is folded over, your vertical IC is probably good and you need to replace the pump-up capacitor next to the IC. When the pump-up cap (typically a 47 or 100uF 35V cap) is open then the picture will have white lines and foldover at the top. The typical vertical output IC is the LA7838, but I am not familiar with exactly which output IC your set uses.
