Television Repair

I purchased a Hisense 65 inch Uled tv four years ago for approx 1400€. Sometimes you get a picture and sometimes the screen goes blank, but there is always sound and a faint light on the screen. does anyone know somebody that repairs televisions? Is it worth reparing?

I have seen this fault a few times mormally means the screen is on way out Oled screens do not last as well as a normal screen
Have you tried a manual refresh mode on the screen Ihave pmd you some setting

I had the same problem you discribed.Hisense sent their engineers 2 weeks ago and confirmed that our 65 in TV purchased in 2018 was not repairable. We still have a picture for about 1 hour then a blanc screen with sound. We purchased a new Hisense 65 mini led in the Amazon prime for 799.00.We still have it on the apartment down stairs for family guests??+

The new picture and sound are fantastic on the new Hisense TV
