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.

I have the same experience with loss of sync error message on the upper-left corner. There will appear the error message about every 2-3 weeks. However, the problem could be easily soved by reset TV although I think is not a root solution.Technically speaking, I think this is a Firmware bug, however, it is rarely for end-user to upgrade TV firmware. I will try to contact the company for any official solution.

Hi There, Im not sure what inputs you are using vga/dvi/ av/ rf etc. In your tv theres a IC that syncronices your display timing etc. This is a advance problem, you should take it to a repair shop to be fixed, they usualy have SMD componants that cant be replaced with a solder Iron.
But Check following first.

  1. If using VGA make sure that your output to TV is not to high herts etc.
  2. Make sure all inputs and cables are OK
  3. Try using a defrent picture soarce see if this works.
PLease let me know
Thank you

If the converter goes out does the tv not do anything no screen light uponly red standby light?


if your question is that if cable or sat converter goes off for any reason , will your tv display a black screen , then the answer is yes , without an input most all tv sets will display the opposite of full white , this being full black , also any on screen displays might not work as well (no video to sync too)

We had a power outage and since my tv does nothing, a tiny red light says standby but nothing changes.


Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

I can't get my Comcast remote control to sync up with this sylvania 32in HD tv. I tried every code in the Comcast DVR manual under sylvania tv's and nothing, I would love a fix to this problem.


the tv is likely to be generic in nature i.e. parts used by many manufacturers. if you knew what tv builder actually designed it you could find the code. does the remote have a search feature if so use it, it should find something that operates most tv functions eventually
