Re: LG 32LC5DCB-UA No Backlights

The replacement power supply IC has the same markings.... 0001 H16. I did remove the old IC. On the bottom there is a marking. It is a circle with H15 in the center. I couldn't cross reference it to anything so it is still a mystery to me......

Ok. Now I have backlights but no image. SMD fuse showing voltage on one side and 0.04vdc on the other side. 63V DC 1.5A with a TK marking. Can't find any info on SMD fuse markings. Any links?
Thanks!

Fuse ordered. Hopefully will be here tomorrow.
I also noticed this fun IC. Now searching for the replacement as I cannot find the exact part# anywhere or the datasheet. TI couldn't help.

Good job, so you have two boards that went out on you.
