Sony is a reliable company... so i guess they should not...
but you can buy extended warranty on the shop
if YLOD occurs outside the Sony's warranty(1-year)
lets say about a month after the expiration... you can still
send the ps3 for repairs for free to Sony... just call them...
but if its long overdue... your doom... you have to pay for the repairs!
PLAYSTATION®2 is the yesterday.....NOW.......still......A_L_I_V_E
