Blue screen only usually means no signal for whatever reason--check all inputs to see if any function---if not suspect main board which processes all signal in the set may be bad.

It most likely is all on the main signal process board which would have to be located and installed to see if it cures the troubles.

Your screen is defective. Screens are very expensive to replace but you might be able to find a used one on line. You will need the part number of teh screen it is located on the back of the LCD panel on a white sticker. Do a google search and see if anyone is selling it. You can try www.interliquidparts.com

Hi again,
I just replied your previous question.
As per manufacturer part policy, LCD Panel consider as One Part though it consist of T-Con Board, Back Light Inverter, Cold Cathode Fluorescent Lamps in lcd panel (according to lcd panel size).
If you ask JVC or any other brand service center, they will answer you to replace lcd panel because of their part policy, but you can replace T-Con board and Back Light Inverter boards in lcd panel just to reduce repair cost.
I'm practicing tv tech and do this kind of repair when required.
Shop Jimmy basically disassemble new tv and sale out boards and lcd panels on reduce price.
Hope this info will help you.

Symptom shows that problem is not related with power supply or fuse because tv shows JVC logo screen then went blank.
It seems issue with digital video processing circuit that is located on main board of tv.
Please unplug tv from AC wall socket for minute to get it reset, replug back in and turn it On and check problem solved?
Let me know model number that would be written at back of tv if problem still not solved.

Fault to the main power supply regulator section. Either it will be a separate board, or the part of main 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)
