Re: Vizio E320i-A2: Power on, on-screen logo, nothing else

I ended up ordering a replacement board off of eBay as the output voltage checked out using the datasheet from the BD9329. The new board fixed the issue of course, so I'm assuming it was most likely corrupt memory.

Kind of a bummer for me I wasn't able to locate a specific fault (this was a learning project after all), but I'm certainly not going to complain about a working TV. I'm sure there will be many more

Ah perfect-- I will look at this and report back.


Right, this board uses a Samsung NAND flash chip instead of EEPROM. I've read that this is common (or maybe required) for smart TVs.

Is it essentially a process of elimination to determine if that's at fault? In other words, is there a way to definitively check for corruption or otherwise any fault in flash memory? Just trying to get my head around the troubleshooting steps for something like this.

Thanks for your...

Hi all-- I'm new here (and relatively new to electronics), and I'm working on repairing a Vizio E320i-A2 unit that powers on (with both the onboard controls as well as the remote) but stays locked up on the Vizio logo that displays onscreen. The LCD and backlight seem to be fine-- the logo is bright and crisp. The unit does not respond to any input (IR or onboard) once it is powered up.

So far:

- The voltages from the power supply check out fine.

- I've checked the voltage regulators on the mainboard and they all appear good. The LD1117 regulators...
