You don't necessarily increase your chances of getting an answer by entering three questions one after another.
It also helps to say where you live - a shop in Kuala Lumpur for instance, may not be up your street.
I think your best approach may be to use Yellow Pages - TV repair shops in your area may know who deals in the spares you need - The Brand Name on the box does not always indicate the manufacturer - quite often the same circuit board may be used in several TV chassis each with a different brand name.
Good luck...
