Screen will not turn on, unless I turn it on and off at least 50 times, at which point it finally fires up.

Select the input channel for your Fire TV - Turn on your TV and select the input channel for the HDMI port you used to connect your Fire TV. You should then see a loading screen with the Amazon Fire TV logo 4.

check for spark . if you have spark it should fire or at least try timing may have gone .

When the marks are lined up on the crank pulley, you have a 50/50 chance the number one plug wire is ready to fire. So you line up the marks and install the distributor so the rotor points to one.
If it does not try to start, take the dist out and turn the rotor 180 degrees and try again.

sounds like a capasiter

Try doing a hard reset of your Kindle Fire as advised on the Kindle Fire Support web site for dealing with Screen problems

If you still have a problem after doing the above, then you follow the additional steps advised on the above web page, i.e. ensure the Kindle Fire is fully charged (the power indicator has changed from Orange to Green) and that you have the latest Software Updates installed (assuming you can view the screen to do so!).

Hi, you can try tightening the ribbon cables that run from the screen to the buffer board , only tighten the one near the line area. if this does not help you probably need a new buffer board or panel (screen)

The Led Problem Just Ask The Technician To Replace The LED With new One.

If the wires are in the correct order, also make sure that you used the correct starting point, otherwise the base timing can be off by as much as 60 degrees. Turn the engine till the crank damper timing mark is pointing to 0 or tdc on the timing scale. If the rotor is pointing towards the engine, turn one more time. #1 is roughly when the rotor is pointing towards the passenger headlamp. Order is in the direction the rotor turns when cranking. If the engine was running with no problems before the change, only other thing could be that you inadvertently unplugged something or the security system armed. Other possibility is that if you did the change due to a running problem, whatever was causing that finally failed.
If when you remove the cap again you find that the rotor is damaged, check the dist shaft for side play.
Are you getting spark?

The firing order is 1, 3, 4, 2. If all the leads have been pulled off the dizzy cap, you'll have to remove No 1 spark plug (leave it threaded into the plug hole by 1 turn) and the dizzy cap. Turn the motor over by hand in the clockwise direction and listen for air being forced out of the No 1 plug hole. When you start to hear that, it means you are approaching TDC on No 1 cylinder. Now look at the front crankshaft pulley and stop turning the engine when the mark on the pulley is close to the marks on the timing belt cover. It doesn't have to be exact (unless you've removed the dizzy). Now where the dizzy rotor is pointing is where No 1 lead has to be fitted. Observe the direction of rotation of the rotor and the next point it comes to will be where you fit No 3 lead; No 4 lead next; and finally No 2 lead.

If it is backfiring the firing order is not correct. turn the crank until the timing mark lines up to zero on the timing cover. Remove the distributor cap, and see where the rotor button is pointed. It should be pointed at number 1. (at this point you have a 50/50 chance) The cam turns half the speed of the crank shaft, this means that even through cylinder number one is at top dead center, it might be on the exhaust stroke instead of compression stroke. If this is the case, you will need to turn the crank shaft one full revolution, and try again.

Reinstall the distributor cap with plug wire number one being placed where the rotor button is pointed. Install the rest of the plug wires in order.
