Question about Cell Phones
When the display is not working, perhaps it is switched of, but more likely there is a defect in the phone, like a bad connection, loose or oxidised, a broken cable lots of other components can be defect, of the back lit screen is not powered.
I don't think you can solve this yourself, perhaps you should visit a phone repair shop, or start saving for a new phone?

PIN CODE is SIM dependenet and not phone dependent
PUK code in PIN UNLOCKING CODE, which is required when you give PIN number wrongly for 3 times,
This code is OPERATOR specific and not phone specific and you have to call you operator and get PUK if PIN is blocked...
if you provide PUK code wrongly for 7 time, you sim may become useless, then you have to buy new SIM
NOTE: You should ask your service provider,get the PUK, give the PIN 3 times wrongly and it asks for PUk,provide the PUK and set the new PIN..

Let me give you a little background and then some solutions. This generic because I don't know your carrier. I've used ATT as an example.
Phones are naturally unlocked, but a service provider might lock them
When originally manufactured, all GSM cell phones are unlocked. That is, they can be used with any SIM from any cellphone service provider - always assuming, of course, that the cellphone service provider has compatible GSM service on the same frequency bands that the phone can operate on.
Most cell phone service providers electronically 'lock' the phone so that it can only be used with their service. There are obvious reasons why they choose to do this - in particular, to force you to pay what are usually very high roaming charges when you take your phone out of their network and use it elsewhere in the world.
Fortunately, this locking is reversible. With some phones, it is possible to simply enter an unlocking password code into the phone and it is immediately then unlocked. Other phones need to be connected up to a special unlocking data terminal.
Your phone has to be unlocked by the carrier. LG, Motorola, Sony Ericsson, Nokia and most of their ilk, will not give consumers the unlock codes but don't despair.
A PUK (PIN Unlock Key) code is required to unlock SIM cards that have become locked following three successive incorrect PIN entries. If your SIM card becomes locked, you will need to get a PUK code from your carrier. For example, if you have AT&T to unlock your SIM card, you can obtain your phone's PUK code from AT&T by:
Once you receive your PUK code, you will need to enter it into your phone to set a new PIN code. Note: If you enter the wrong ATT PUK code 10 times in a row, your SIM card will be invalidated, and you will need to purchase a new SIM Card. The phone will display the following error: "PUK blocked call operator." There are three other ways to unlock a phone:
I trust that this is helpful and solves your problem. All the best
