Ace Logic will charger 250 peso to fault find. If its the motherboard, ask them for the part number on motherboard and how many pins on screen ribbon. I use Aliexpress for all my needs and if you do a search I'm sure you will find a motherboard for half the price of locally sourced. Anyway get the fault finding done, then decide your next step. I have just ordered a new motherboard for my Compaq Presario CQ56 on Aliexpress for $60 with free shipping, downside it takes 60 days delivery. You can get them couriered but you will get hit for customs duty.
