My Samsung smart TV is showing an alternating solid colour screen. Sound is OK
Hello, I'm Shahid and will be happy to assist you. I need additional info of TV symptoms to troubleshoot the problem. This is not an answer so do not rate it.- Can you please get me the model number written on back of TV?- How long the TV left unplugged, 10 minutes or more?- Are you using Samsung remote came with TV or any universal type remote?Thanks.

I can't get the model no because it's wall mounted and I can't get to it
It was unplugged for about 5 minutes
I tried its own remote and a Sky+ one
OK, does the TV menu screen come up when push menu button on TV or its remote?

No, nothing comes up

Sorry to hear that, alternating solid color screen appears due to corrupted firmware (TV internal software) and it happens when EEPROM (memory) chip gets internal failure, EEPROMN chip stores firmware data and this chip ins't available separately thus entire main board of TV will be replaced to resolve the problem.If you wish to replace the main board yourself then remove the back cover of TV and get the part number off of label/ sticker pasted on main board and search/google it to get price info to order it and if you're not comfortable working on TV yourself then local TV tech will do this job for you.I trust my input will help you out. Please feel free to respond if you have any additional questions.A positive rating to answer would be greatly appreciated, please click on smiley face/star on this page then click submit/finish button so I can get credit on website for my work.
