I tried to replace the backlight LEDs in a Samsung 65" TV. It had the typical blue/purple areas in several places. Having received replacement LEDs i attempted the repair. These things are NOT made for disassembly. I've worked on all sorts of electronic equipment as an amateur, but this was a nightmare. In addition, i got a shock and i think some of it went through the TV electronics. Having painstakingly replaced the LEDs, which was a nightmare as they friction fit and did not want to come out. There was a new issue which ruined the picture. A total disaster, so in my view these TVs are not repairable by non experts, despite UA-cam videos claiming otherwise
i have a old monitor that is flickering on and off at random times that im happy to send to you if interested. it will make a interesting video to see what was wrong with it. had it for 7 years with no issues then 1 day it kept disconnecting.
OK. I am confused. You have effectively disconnected something with the paper insulator trick and now the set works. I have obviously missed an earlier video where you probably explained this, although I couldn't find it. Can you please explain? Thanks!
@@mistermikeanson It’s a short circuit/ high voltage error on 1 up to 4 CLK clock lines. There are up to 8 independent CLK feeds so blocking of the faulty ones regains image. This is a common fault but it’s not a common fix. Sometimes the image returns with lines. On this model is a perfect image.
Or anything else these days. I've had their phones fail although the fridge freezer and washing machine is still going strong after 10 years. I think their quality control fell off a cliff in recent years
Spot on thanks Allen 😊

It always seems to be the 50 inch versions of the Samsung Tv's that fail in this manner.

Am I correct in thinking that on my Sony set, the clock lines would be CKV 1 to 4 and CKVB 1 to 4?
@@tdub8719 yes. 8 in total.

Never a Samung TV..
