Do you have the Samsung remote? Can you pull up the menu? Is the menu clear or also affected?

I can just make out menu

Have you tried unplugging the tv POWER cord for 3 full minutes?

Ask Your Own TV Question
Customer reply replied 8 months ago
Did for one minute
TV Technician: Mike G., Technician replied 8 months ago

Might try for a bit longer but I wouldn't count on that helping. Unfortunately there's nothing you can do in this case except replace the Main board in the tv. That's the board with all the audio/video jacks. I can help you find the board if you like but it might only be available used....

Because I did a firmware update from Samsung?

Restarting tv
TV Technician: Mike G., Technician replied 8 months ago

Yes, sometimes it goes bad in that way...

There isn't a factory reset before 2008?
TV Technician: Mike G., Technician replied 8 months ago

The only reset I know of is in the Service Menu but if you cannot see the menu...

I am able to make it out
Customer reply replied 8 months ago
I can see that a little better than actual broadcast
TV Technician: Mike G., Technician replied 8 months ago

Oh, ok. Here's the thing. The Service Menu is very risky. There are many things that you can screw up in the Service Menu. AND I cannot tell you where in the Service Menu the Factory Reset is, YOU will have to find it (once you get into the Service Menu). So all of this is at your own risk...

Ask Your Own TV Question
Customer reply replied 8 months ago
Willing to take the risk
TV Technician: Mike G., Technician replied 8 months ago

Also, there is a good chance doing the Factory Reset won't even help your situation... But here are the instructions to get into the Service Menu:

-turn off the tv

-point the Samsung remote at the tv

-press MUTE, 1,8,3

-the tv should turn on and there will be a complex menu on the screen

-move around in that menu looking for Factory Reset

Be aware when you press the RIGHT arrow, it is like pressing ENTER, it will initiate whatever is highlighted.

Didn't start
TV Technician: Mike G., Technician replied 8 months ago

Try mute, 1, 8, 2, power

Ask Your Own TV Question
Customer reply replied 8 months ago
Nope
TV Technician: Mike G., Technician replied 8 months ago

That's with the tv powered OFF and pointing the remote at the tv. Pressing the buttons quickly in succession.

Customer reply replied 8 months ago
Yep and watched red light flicker with each click fast and normal clicking
TV Technician: Mike G., Technician replied 8 months ago

Sorry that is the proper code to get into the Service Menu.

Main board for this tv is on eBay for $40-$55

Ask Your Own TV Question
TV Technician: Mike G., Technician replied 8 months ago

Just be very careful to get the correct board (there are a few different boards for this model and they are not interchangeable). Suggest you open the tv and get the numbers off your board BEFORE ordering something.

Ask Your Own TV Question
Customer reply replied 8 months ago
Really?
TV Technician: Mike G., Technician replied 8 months ago

We've seen this many times before (not just Samsung)... Only fix is to replace the board that has the firmware on it.
