We had major power flashes the other day and my Sanyo dp50740 Plasma TV went on an off and then it shows no signal. I changed out the HDMI cables and the receiver and nothing works. I tried different inputs and my blue ray would bring up a picture but no sound on the HDMI input 3
Is this a good question?

Did you have your TV and the other components plugged into a surge suppressor strip or UPS? Do you have a ground connection for the cable at the cables entry point with good mechanical grounding?
It sounds like your TV and/or the HDMI connected components got zapped. Not much one can do here sorry to say. The issue is costs you can get a bigger and better LCD (LED backlit) TV now for less than what you paid for your plasma than the cost of repairing your plasma.
You could checkout what your home owners/renters insurance covers. You maybe able to get some money to cover some of the cost of the replacement unit. I would strongly recommend getting a good quality surge suppressor or better yet a UPS (My big TV and the other gear I have with it are all plugged into UPS). In addition see about getting a whole house surge suppressor (do both) and check your ground services. It could save you next time.

Hey Dan,
I know it's been over half a decade since this post but I've been faced with a similar power outage issue that broke the HDMI ports on my 10y old LD LE5500 42" LED TV. I had plugged it into a stabiliser but that didn't seem to help either. Since you suggested the idea of a UPS, will the conventional modified sine wave UPS suffice or should I get the pure sine wave one?
Thanks!
UPS systems can have either sine-wave or simulated sine-wave output. A simulated sine-wave UPS is the cheaper and for most devices will be fine.
A double-conversion (online) UPS provides consistent, clean, and near perfect power regardless of the condition of incoming power maybe more important depending on where you live and how dirty your power is.
A good way to 'see' how bad it is only requires having LED lighting. Unlike incandescent & fluorescent lighting which is slow in its response, LED is very fast and is sensitive to square and clipping of the wave-form. Basically you'll see the flicker in the light!
