I want to open cable TV box (general instruments) for power supply repair. It has special screw heads. Unfortunately we do not have screw drivers for this type. Could you please let me know any web, or details of tool manufactures to order special screw driver bits.
MCM Electronics has a 32 piece 'security bit set' for sale for $8.99 usd.
They're at www.mcminone.com and it's pn#22-1875.
Don't know if the right one for you is in this set, like audioguru said , it's best to contact manufacturer..
