Here is the information from the Tracfone website.
Transfer Number > Phone Upgrades

• What is a phone transfer?A transfer is when you wish to transfer your phone number and minutes from one TracFone to another.
• I just bought a new TracFone. How do I transfer my phone?
  In order to transfer your phone, go to the "Activate/Reactivate Phone" button on our website and then select the option that you need. You can also contact our Customer Care Center at 1-800-867-7183 so that a representative can transfer that information for you. Please note that when you complete a phone upgrade from a smartphone to a non-smartphone, you will not be able to transfer any remaining minutes in your account, so you will lose those minutes.
• If I buy a new TracFone, can I transfer my remaining minutes and phone number to the new phone?
  Yes, you can transfer the minutes and phone number into your new TracFone by going to the TracFone main page and clicking on the "Activate/Reactivate Phone" button. Then, select the option that you need (phone, SIM, or Bring Your Own Phone CDMA). You can also contact our Customer Care Center at 1-800-867-7183 so that a representative can transfer that information for you. Please note that when you complete a phone upgrade from a smartphone to a non-smartphone, you will not be able to transfer any remaining minutes in your account, so you will lose those minutes.
• If I currently have a TracFone smartphone and want to transfer to a non-smartphone, will I be able to transfer my remaining minutes to my new phone?
  No. When you complete a phone transfer from a smartphone to a non-smartphone, you will not be able to transfer any remaining minutes from your old phone (so you will have to forfeit those minutes), but you do get to keep your service days.
  

This 30-minute learn procedure should be used when all vehicle keys are desired to be replaced or reprogrammed. This procedure will erase all previously learned vehicle keys from the TDM. Once the 30-minute learn procedure has been completed, any remaining vehicle keys may be programmed using the Adding Keys procedure to ensure their continued functionality.

1. With an unlearned master vehicle key, turn ON the ignition, with the engine OFF.
2. Observe the security indicator, after approximately 10 minutes the telltale will turn off.
3. Turn OFF the ignition, and wait 5 seconds.
4. Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes.
Important: The TDM learns the key transponder information upon the ignition switch transition from OFF to ON. You must turn the ignition OFF before attempting to start the vehicle.

5. With a master vehicle key, start the vehicle. The vehicle has now learned the key transponder information.
6. If additional keys are required to be learned, refer to Adding Keys.
7. With a scan tool, clear any DTCs.

1. try to remove positive power cable from your battery and wait for 5 minutes.
2.while waiting for 5 minutes,Drain all remaining power by switching your ignition to ON,switch on your headlights,step on your brake pedals
3.switch off your ignition ,including your headlights
4.install back your positive power cable to your battery
5. try to start your engine

If the standby light is not ON but there is power to the circuit, check the +5 to the processor section. If this is present you need to check the processor for oscillation ( Only if equipped) If not the fault relates to non functioning of the processor controller.

There are two possibilities for that symptoms,
Either standby power supply becomes low (less then +5 volts) so system control chip lose its function OR system control itself stops its function.
Unplugging TV resets system control and it starts work again.
First confirm standby supply is OK, if found good and correct +5 volts, then replace main board that has system control chip.
Let me know exact model number of your Sony TV written at back to find out boards and prices.
Thanks.

Go to local Thif stores or Pawn shops you can buy a working VCR for$ 5.00-$20.00 ,you have a power supply problem.

you dont need a service manual. the problem is the convergence chips and it has been plaguing these pioneers for years it is either the bad solder joints on the chip itself or the chip is trash anyway go to tvrepairkits.com and they will help you get everything u need

Many of the later model Sony TV?s have a built in self-diagnosis function. AKB circuit (automatic kine bias), the timer/standby indicator blinks 5 times for about 30 seconds then goes to the self-diagnosis function. In other words, the IC chips on the Cboard are burned out. This repair is not one that should be attempted by the end user. This repair will need special test equipment. You will need to take it in for repair. It shouldn't cost more than $170-$200. This is cheaper than a new TV set.
