The fact that the hair dryer allowed the set to come on tells me you have capacitors in the power supply that are leaky. I'd on the board as C1,C2 etc. The value of the part will be on plastic like caseing example 1000uf 25v. Look for a slightly domed top. That will be the bad ones. When replacing these make sure you put them in the same way as the ones that were in the set. They have a positive and negative lead. If you put it in reversed the new part will explode.

There are 3 digit, 4 digit, 5 digit, 2 digit and even single digit codes, to some brand devices. After confirming this, check the sites linked here. Both the sites have set-up code list and set-up procedure to many popular brand remote controls. Check which brand remote control has set-up code/s to your device brand, and buy that one according to availability.

Please note: Every new universal remote control will have set-up code list, and set-up procedure along with its pack. Never accept a remote control, that hasn't both of this. For more details about the set-up codes, visit the sites.
