If the HDMI cable was the only connection, then the high voltage pulse would have had to go through one or more of the video wires in the cable, through the video board, and back out the HDMI cable shielding. What troubles me is you should see the unit come up to standby and refuse to power on. That suggests there was something else connected besides the HDMI cable or the base made a decent ground. At least the panel is worth $150 or so (it is highly unlikely it was damaged).

Did the fuse blow? And when you put in the new fuse, did it blow right away.
For five year old TV, the common failure will be the power supply module and the processor on the main board since it will be running 24/7 even when the TV is off, this make it subject to all kind of surges and spikes (I kill the power my TV's when not in use using my power conditioner power switch).
The main board can be damaged also.
Repair shop will more likely to charge you $50 to give you the estimate, typical repair will be $150 and up plus parts.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Hi,
If there's no LED light at the front panel, this is an indication that the power supply board is not working/dead (I'm assuming here that you had already tried to plug it to other working outlet). First part to check in this kind of symptoms is the internal fuse of the power supply board. It is where the power cord's directly connected. If your unit is not under warranty period (if so, avail it because the manufacturer will fix it for free) open the back cover, check the continuity of the fuse using the multimeter. If you found it open replace it with same current(ampere) ratings and then try to power on the TV. If the new fuse blew again, this is an indication of more serious problem on the power supply board.
Let me know the status of the fuse and the exact brand and model no. of your TV to assist you further.
