Can I fix an Onn Roku TV (58 inch) No Display

Got a free 58inch Onn Roku TV with no display (no physical damage). Can I fix it?
Video from Frugal Repairs related to TCon board and taping the ribbon connector - • I fixed a broken 4K 55...

Thank you very much for this very helpful video. My 65 inch onn TV started working again. There was only one difference, when I disconnected the ribbon cable on the right side, half of the screen turned white, and when I disconnected the left side from the T-con, nothing happened. In video, you had at least half the picture. Desperately, I started trial and error with tape and randomly covering a series of connectors on the right ribbon cable until I saw the complete image, but the quality was not good, and lines were also visible, and the light on the upper left corner of the screen was increasing and decreasing. . In short, I think that I only covered the connector number 15 or 16, the picture came back great and now the TV is working without any problems.

Your resets will return your volume all the way down so you can't even hear the menu navigation beeps. Just use your remote and turn the volume all the way back up.

Those clock signals simply identify the makeup of a pixel in the circuit to which they're assigned. In other words, it tells a pixel what position it should be in, what color it should be, how long it should be there, how bright it should be and so on. If the clock circuit is bad, those pixels will simply be invalid.

Actually you have a bad power board, yes turns on but it has a short somewhere and won't show the picture, seen this many times with these models.

I've taken the back off of all my TVs and drilled holes and installed a noctua NF-A14 140mm 5v fan. Some on Amazon come with a usb adapter. Most TVs have atleast one 5v 0.5amp USB output. You plug the fan into the TVs USB port. You dont have to get noctua you can get AC infinity they come with USB. Literally have never had a TV issue. 99% of TV issues is overheating components.

How do I know which part I need. My tv is a 55” onn Roku tv.

[@tracieepps2604]

You never said where you got the part from

[@CLEFFJOE]

Perhaps from de manufacturer

[@besi1974]

check power board for bad capacitors (bulging top) dont buy a new board just swap out the capacitor.

[@bbgarnettTotallyNotABot]

Also if this were in my area people would have been asking like $200 for this TV in the non working condition.
