Hi Guys ,got this TV in for repair . Only see the JVC emblem for a second then screen goes blank . Suspected backlight LEDs and took screen apart . To my surprise there were no visible LEDs . It has a Vestel 17IPS71 power supply. Only lights are on a board on the right hand side as you look at the TV from the back . It seems to be one vertical strip . Have left pics if you want to see . Does anybody know how to check this strip.? thanks
