HDMI No Longer Working Toshiba Laptop

[Disco_Ruprecht]

I can no longer get HDMI output to work from my home Toshiba C50 laptop.
It did work last week to my sony 70" TV through Marantz receiver however I have now changed to a Yamaha RX-V381 receiver and cant get HDMI to work.

Note that my work laptop outputs fine through receiver to TV or just to TV. The home Toshiba laptop does not work on any of the three HDMI devices I have tested.

I have tried updating drivers and setting monitor out options, the other thing to note is that I do have an external monitor on VGA output, works perfectly. Any help would be appreciated I have worn out google trying to solve this.

Well HDMI does carry voltage and such, and "hot swapping" or plugging in cables while the laptop is still on could have shorted something and possibly fried the HDMI port. If that's the case, there isn't really much that can be done. Repairing such a thing, would be a wild electronic goose chase as it could be anywhere from the digital output options from the GPU itself to the pins or a fuse near it and any bit of actual meters and meters long of trace and components inside the laptop. Your possible one option would be to get a USB to HDMI adapter and use if its for general stuff like browsing and may be powerful enough to watch a movie, but those adapters aren't good for gaming and such.

It seems your tried all the options. VGA works, meaning analog output works and the system is capable of extending.cloning, recognizing a 2nd screen, so drivers/gpu works. Laptop screen work, so again gpu's basic functions work.

Other laptops work through the same cable and input devices, so it is neither the cable, nor for the input device itself.

This leads to the HDMI port, or digital output portion of hte laptop not work, and as said, not a easy if possible at all fix.

Thanks for the quick response I really appreciate it. Now that you mention that the HDMI port can be damaged I realise I forgot to mention that the previous Marantz reciever was killed by a power surge. Maybe some of that nasty voltage made its way through the HDMI port at that time. I will look into the USB to HDMI adapter though, I didnt realise that was an option and may be my only one. Thanks again.
