Hi Everyone
I have an LG 43UK6300 TV
After 2.5 years of use, the image disappeared all of a sudden but I can hear the sound (even the sound that comes from my PC /HDMI)
I want and I will repair it myself. But I need a small piece of advice.
I baked the motherboard at 200 degrees in the oven for 10 minutes (Utube Video) and the only result: I feel dumb

- it didn't help.
When I opened the TV I saw that the LED lamps are working. They emit light
My next step: buying a Multimeter for checking the LEDs
I never worked with one. Will you think that this one should do the work?

*If anyone has a suggestion / another step that I should follow - I will be happy to hear
*Should I check also other components with the Multimeter?
