I read your other thread on this.
I strongly urge you to not try this. If your first foray into electronics repair is a TV, you could die. Let me repeat that...you could die.
We have a 2+ year old 32 in LCD TV, with visible burn marks on the HDMI port. There is a long chain of electronics between the power cable and the HDMI port. Any or all of which could be cooked in some way.
There is no way a 'tutorial' could show you how to fix it, unless you already had a pretty good electronics background.
A 32" LCD is pretty cheap nowadays. The parts, if you could find them, would probably not be much cheaper than a new unit.
With exactly zero guarantee of working.
Either take it to a TV repair shop, or just get a new one.
I repeat...do not do this.
