Hi this Pi no longer will Boot from any SD card for any Pi OS distribution. 

Reformatting the SD cards has no effect and writing the OS fails to read much less boot it.

The Red LED is lit for power indication but the Green never lights. 

There are no accessories installed on the PI.

I’ve tried the boot loader nothing helps.

Is there a secret back door to get into the EPROM or something? Maybe accessing it from Windows 10?

Looks like this is now a paperweight ??

Thanks for Helping!

Check to make sure that your power source has sufficient current (i.e. the voltage isn't sagging, since the Pi prefers 5.1-5.3 volts, and that you've got a sturdy cable delivering that power). Did anything change in your power source since it was working before?

Hello Bill,

Hi this Pi no longer will Boot from any SD card for any Pi OS distribution. 

Reformatting the SD cards has no effect and writing the OS fails to read much less boot it.

Let's start with basics:

? 1. Is this an existing SD card or new SD card?? If it's an existing SD card, please note that depending how you were using it, they can and WILL go bad.? I would recommend to try a NEW brand-name SD card like a real Sandisk card from a known trustable source.

? 2. What tool are you using to write the SD card?? It's possible to create non-bootable SD cards.

? 3. Are you sure you have a very solid 5.1 volts into the Raspberry Pi.? Check the voltage on the correct GPIO pins using a volt meter

The Red LED is lit for power indication but the Green never lights.

On the HDMI display, what do you see?? Do you see the Raspberry Pi rainbow color display??

There are no accessories installed on the PI.

I’ve tried the boot loader nothing helps.

Are you thinking of the Raspberry Pi 4 boot loader?? If so, that won't work as the Raspberry Pi 3B+ hardware doesn't use it.

Is there a secret back door to get into the EPROM or something? Maybe accessing it from Windows 10?

As mentioned above, there isn't any boot eeprom on 3B+ units and there aren't any published diagnostic documents of how you might troubleshoot the hardware per se.? There are a TON of Internet search hits on "Raspberry Pi 3B+ won't boot" that you can follow up with.? Some might be helpful but most will say the same things I just said above.

Looks like this is now a paperweight

All hardware does fail in time.? Maybe ESD got it.. maybe a power surge got it.. maybe it's just it's time but it's most likely a failed SD card or power supply.

Hi 
No nothing changed on my Power Supply this is the newer model PS which is about 3 months old. I could try my original PS that came with the original shipment even though that did give the insufficient voltage on screen message sometime ago but always booted.

I also use external battery packs that won’t boot it either. I have swapped out the cables!

I did the easy approach first David- a brand new SanDisk card same issue No Boot green Led out.?

I believe it’s gone but no will use the Pi Zero 2W.

Thanks?

I bricked a Pi 3?a while back. ?It was not in a case and I think I shorted some of the pins on the bottom of the PCB.?It had similar symptoms to what you describe.

It was a good excuse to get a Pi4 at the time when it was easier to find them locally.

I think that’s what happened Jamie I had a 1 1/2 inch tiny monitor connected to the GPIO pins but the Pi was in the case. So migrating to my Pi Zero2w now. Being careful now!
