Thomson TV no backlight again

[andrebdnw]

Hi there,

i received a TV in which the backlight did not work. After that I disabled the protection (pin 11 with 10k ohm to ground). The TV worked for 2 weeks, now it has the same error. I have redone the solder joints and replaced the 10k ohm resistor with another 10k ohm. unfortunately it does not work. Does anyone have any ideas? LED driver: OZ9976GN

remove yours stupid Indian DIY and go straight to replace LED strips if the issue remain then yours IC worn out.

When I turn it on, the backlight flashes. I don't have an LED tester, but I suspect the LEDs may last a few more weeks. I am planning to buy a new TV. It's not worth the hassle of repairing it.

Ok, why did you waste our time if you didn't plan on repairing it?

probably enough leds have burnt out that nothing short of replacement will work.

This fix is like disconnecting your check engine light in your car if it comes on. Problem solved!
