I tried puff HTV for the first time and I’m really happy with the result! I used it for the brown parts of Sackboy and regular HTV for the rest of the design.

I actually found an old post here where someone tested different temperatures and pressures with puff HTV, and it helped a lot with figuring out where to start.

I used CHEONET puff HTV at 300°F for 10 seconds with an HTVRONT Auto Heat Press. Hope this helps anyone else experimenting with puff HTV!

Hi everyone,

I'm trying to diagnose a Razer Blade 14 (2017, 7th Gen Intel) and I'm hoping someone has seen this before.

The laptop originally only powered on with the keyboard backlight. There was no display and no HDMI output.

After disconnecting the main battery, it suddenly booted one time. It showed:

The Razer logo.

The message telling me which key to press to enter the BIOS.

A few seconds later, the screen went completely black before I could enter the BIOS.

Since then, it has never displayed anything again.

Here's what I've already tried:

Disconnected the main battery.

Disconnected the CMOS battery.

Left it without power for 30 minutes.

Held the power button to discharge everything.

Booted with and without the SSD.

Reseated the SSD.

Tried an external monitor via HDMI (no signal).

Repeatedly pressed F2/Del during startup.

Current symptoms:

Keyboard backlight turns on.

Power LED slowly blinks green immediately after pressing the power button.

No fans.

No display.

No HDMI output.

The strange part is that it successfully completed POST once, showing the Razer logo and BIOS prompt, but has never done it again.

Has anyone experienced something similar? Could this be a BIOS/EC firmware issue, or does it sound more like a motherboard failure?

Any ideas would be greatly appreciated.

Thank you!
