WOW i fixed a NIKAI 75inch TV that was spilled with rain water during heavy rainfall. NO Power, shorted and found 2 mosfets defective.

Replaced 2 MOSFETS 65R600Q and 1 fuse. Very happy for this guide.

Hi, i received a 75inch NIKAI TV that was in good operation but suddenly get water-spilled due to heavy rainfall and intrusion that went inside the TV and shorted it out.

Aftermath, busted fuse and 2 MOSFETS 65R600Q T0-252. I was trying to find an alternative because it is hard to source out this part.

Hope you can share your ideas.

Hi. I have a hisense LEDN50K20DGP. The backlights went off when we had a power failure at home. The TV has sound but no picture. When doing trouble shooting it came down to 1 led backlight being dead on the led strip. A friend took 1 led from another strip and soldered it on. Now the backlbacklight only come on when i use a wire on the previously dead led from positive to negative. Could he have soldered the led wrong way around?

Yeah, it is always better if we can get a manual. But anytime people have a problem with a LED, they should always trying reflowing the solder first before assuming that the LED is bad.

You were very lucky you only had bad solder joints, Robert. The problem begins when you need to replace those bad LED's. And finding the right ones. Because it very often are blackened burned failing LED's. Sometimes even the new ones fail after a few days.
