A customer just messaged me and after moving from one location to another and plugging in their hisense tv all it does is cycles thru the different colors like its in some kind of test mode.Standby light is red and remote is unresponsive.Have tried unplugging it but no change .Tv was fine before they moved and this happened right after they moved into their new home.Any ideas.

Re: Hisense 65H8608 screen cycling thru colours
I was told once that if your main board stops sending a LVDS signal but the 12V supply to the TCON is present then the IC on the TCON goes into self test mode. I have never tested this so i don't know for sure but the only advice i can give you is to remove the LVDS cable for both sides clean it with isopropyl alcohol and reseat it. Maybe it is a bad contact causing this issue since the tv was moved maybe the tv had a bump.
Others in the forum can maybe better advise you. -

Re: Hisense 65H8608 screen cycling thru colours
You were spot on angelos. Removing cleaning and reseating the LVDS cable brought the tv back to normal.Thanks so much for helping to solve this problem and I would say it confirms exactly what you stated about the tcon getting 12v but no signal gives the screen test mode.Comment

Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!
My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.
This time the original cable broke too close to the screen, it can't be fixed without tearing the screen... -
Hi,
I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on... -
Hi all, I need to change the backlights in a Hisense 55E76GQTUK. The screen is glued to the chassis, what is the easiest way of delaminating the screen from the chassis please?
also what double sided tape would you recommend to glue it back in? ….. or is that a question to ask once the screen is out in one piece?
Many thanks for any ideas you have. -
Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same... -
