This seems like a convergence issue and will need to be serviced.

There might be a chance of repairing the old convergence board but you will need to have the Tv looked at to determine what part on the convergence went bad. Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620

Sounds like static electricity caused some damage somewhere...you never want to try to vacuum a TV or use a cloth or brush, only thing that is safe is air like is used to clean a keyboard...you damaged a board in the set, could be the main or tcon or both

Actually it could be the color wheel issue not spinning at the correct speed. They are suppose to spin at 60 HZ. My suspicion is that it is slowing down so you are seeing with your eye the slower speed.

It is but they don't make it easy to get at as I believe you have to remove the whole Light Engine to get at it. They would prefer a qualified technician would do this type of repair.

If you still have picture, and the sound was working before this--you may have lost the audio amp chip. I hope you are not running a bunch of external speakers on the tv here--this WILL kill that chip !!

yo possibly have light engine problem

If it is a high pitched or even fan like sound it may be the color wheel in that set which if I remember is not sold except with a complete light engine, do some research on that model for color wheel.

Some simple things to be aware of: A lamp (generic cheap) or one reaching the end of its life can cause this issue, what is age and brand of lamp in the set?

need accurate model number and brand--see multiple posts here from you with different info

Then get a job like your TV is telling you. This will fix your TV, because you can then just buy a new one.

OK. I have this same issue. I replaced my bulb a month or so ago. TV worked fine. Then one morning I turned it on and it was on for a good while, till it went to a black screen w/ sound only. Lights were going through the reboot process as designed for 8 attempts before it went to the solid red light. From the red light, if I unplug and plug back in, the tv will come on for a given amount of time, which varies, and then cut to the black screen. A repairman told me that it sounds like the digital board is bad. He wanted $150 for the board and $100 labor. I cannot find anywhere where the board would be located or where I can purchase a replacement.
