Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

You can't do anything without a remote. How can you not have a remote for it! Just buy a facsimile remote, the same as the old one.

In general the TV is not receiving any input. The fact that you lost HDMI and VGA earlier suggests that there is a breakdown in the input circuits.
Best guess, replace the main board. Symptom doesn't seem to indicate Power supply or TCon board

I'm not sure what you mean by large black shadow, but it may be your screen that is failing. Ask friends for a honest repair person to look t it and tell you what they think the problem is. I wish I could tell you more,m but a large black shadow is not one of the symptoms I ever heard of.
