Question about Dynex Televison & Video
The tv will light up slightly with the back light but it will not get the actual picture. It is not the box I had my cable company come out. The cable guy said he thinks a power surge blew a capacitor. He said it happened to his samsung and it was a $1.50 fix
a 6ya expert can help you resolve that issue over the phone in a minute or two.

If you've done the flash light test, it could be the inverter board became defective but it could also be that the power supply does not provide the +24VDC to the back light inverter board.
If you could do the +24VDC test using a voltmeter then we can say for sure that the back light inverter board is defective.
Let me know if you need further assistance.

To eliminate power in as a problem get a small battery backup type UPS. This will eliminate power surge spikes, brown outs and for short time periods blackouts. Yes - these TV's are suseptible to power problems.

I am sumising that you have checked the menu controls on your tv and are recieving your signal from the cable box , so therefore if it is not comong from the Aerial and direct from the cable company then the picture should be clear .. However sometimes people dont check to see if the signal is RGB or composite from the box RGB is usually best if you have a scart socket connection or SVHS if your set has that capability .. sometimes people have an old VHs recorder and the sinal is coming from that to the set through the Aerail fly lead if it is you will probably find they are conflicting giving you a poor picture retune your Video to another channel instructions should be in its manuel if not come back to me ... reagrds Vortash

The warranty does not cover lightning, check if your insurance covers it.
A lightning strike on such panel ( HDMI ) is very difficult to repair and if not impossible.The HDMI connector is hooked to the ground of the TV set so everything could be damaged.
My advice is not to repair.

I have a ln-s4092d that had the same problem after a little more than a year of service. Replacing the main board seemed to fix the problem. But about a year later, the same problem has reappeared. I'm getting ready to replace the main board once again, but I don't really want to do this on an annual basis/
