Have TV Questions? Ask a TV Technician
Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.
Initially, bear with us; re-confirm and post back with the complete model number of the Samsung. It would normally be printed on a sticker/name plate at the back of the TV.
Sorry, not the serial (S/N) number but M/N or Model:?
Appreciate the additional information.
Is the description of "...screen is blank..." referring to the whole screen that is blue, black or white?
Consider an experiment (if have not been done). Power on the TV and set to a program/channel. If at all possible, darken the room where the TV is. Wait for about 5 minutes or more. Shine a flashlight at an angle (not directly) and nearly but not touching the screen where the volume level / menu display is usually seen.
Press the VOL UP/DOWN or MENU button and note if a dark/ghostly image of the volume level or MENU could be seen.
The above is a test to determine if it is a backlighting issue.
Last easy user doable try; unplug for an extended period of time. This is to simulate a SOFT RESET.
Plug back in but into a different outlet.
All others would point to a most likely internal hardware issue.
Unplugging for an extended period of time would simulate a SOT RESET.
Consider giving this a try.
If not corrective, then it would confirm the internal hardware issue even if it were just a loose connection.
Are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter (and even perhaps a soldering iron)?
More importantly, would be comfortable working on the inside circuitry? ...LIVE?
Would LINKs to potential independent TV repair shops serve your need?
Sorry; "...replug in my computer..." ?
Great! Good to hear that the issue has been resolved, congratulations.
It would appear that the SOFT RESET served its purpose.
