Need to find a new motherboard for my Philips TV

Hey! So my 3 year old Philips tv broke, gives me the red blinking light and I have been to two TV repair guys. They both said they can't order a new motherboard since there are none in stock. Is it possible to find a new one somewhere on the internet? I paid quite alot for the TV and I quite like it, dont want to let it go to waste. The model no is : 40PFL8008S/12 Serial no: ZH1F 1334 008922 Thanks!
