HIsense Back lights

[provider10]

HI
I got 2 hisense LEDN40K20dp tvs with most of the backlight LEDs blown.
In total there are 40 LEDs inseries which need s approx 120 volts. From the PSU I am getting a constant 240volts, so i suspect this is the problem. Hisense says this is an obsolete set so no spares. Anyone been here before
Regards
Jim

Re: HIsense Back lights

If the LED driver is not seeing the load (LED string not connected or open circuit in the LED string), the output Voltage will be higher than the loaded Voltage.
Do you have good clear pictures of the power supply board and the pictures of the whole backside of the TV showing all the boards?
