Looks
Expert:  Mike G. replied 1 month ago.

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

Customer: replied 1 month ago.
I can just make out menu
Expert:  Mike G. replied 1 month ago.

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

Customer: replied 1 month ago.
Did for one minute
Expert:  Mike G. replied 1 month 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
Expert:  Mike G. replied 1 month ago.

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

Customer: replied 1 month ago.
Didn't help

There isn't a factory reset before 2008?
Expert:  Mike G. replied 1 month ago.

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

Customer: replied 1 month ago.
I am able to make it out
Customer: replied 1 month ago.
I can see that a little better than actual broadcast
Expert:  Mike G. replied 1 month 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...

Customer: replied 1 month ago.
Willing to take the risk
Expert:  Mike G. replied 1 month 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.

Customer: replied 1 month ago.
Didn't start
Expert:  Mike G. replied 1 month ago.

Try mute, 1, 8, 2, power

Customer: replied 1 month ago.
Nope
Expert:  Mike G. replied 1 month ago.

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

Customer: replied 1 month ago.
Yep and watched red light flicker with each click fast and normal clicking
Expert:  Mike G. replied 1 month ago.

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

Expert:  Mike G. replied 1 month ago.

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

Expert:  Mike G. replied 1 month 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.

Customer: replied 1 month ago.
Really?
Expert:  Mike G. replied 1 month ago.

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

Customer: replied 1 month ago.
Ok thanks
Expert:  Mike G. replied 1 month ago.

Apologies again for the bad news...

Customer: replied 1 month ago.
Ok I'll check it out. Picture looks as good as it did new
Expert:  Mike G. replied 1 month ago.

Ok. All the best.
