Changing the Language on a Sanyo Gorilla Device
I dealt with this a few years back when a client brought in a Gorilla projector that had gotten stuck in Japanese after a firmware update from an Asian vendor. The menu was completely unreadable. You won't find a straightforward answer on Sanyo's site for this one, since they don't exactly publish a language-switching guide for every model. First, figure out which exact model you're working with. The Gorilla line covered a few different product types over the years — projectors, signage displays, portable units — and the menu structure varies between them. Look at the label on the back. It'll say something like PLV-Z3000 or XE1040 or whatever. Once you know the model, the general path is usually Menu -> Setup or Settings -> Language. The problem is that when the device is already in the wrong language, you're navigating blind. Here's how to handle that:
Most Sanyo Gorilla projectors use a numbered icon system for the main menu. The Setup menu is typically the third or fourth icon from the left. Inside Setup, Language is usually near the bottom, often the last or second-to-last option. This isn't universal across all models, but it's close enough to be a starting point. If you have an HDMI source connected that outputs on-screen display text, some newer Gorilla models will show the menu labels in the source language while keeping the underlying options in the current language. That won't help you navigate, but it can help you confirm you're in the right menu. The workaround I ended up using was straightforward. I took a photo of each menu screen with my phone, looked up the model number plus "menu" on Google Images, and matched the icon layouts. Sanyo's own manual PDFs sometimes have color screenshots of the full menu tree. Searching for "
One thing people miss: after you change the language, some Gorilla models require a full power cycle. Just cycling standby isn't enough. Unplug it from the wall for about thirty seconds, then power back on. I learned that the hard way when I changed the language on a PLV-DL7800 and the menu stayed in the original language even after confirming the selection. The unit hadn't actually committed the change to non-volatile memory until it lost power. There's a complication with region-locked units. Some Sanyo projectors sold in Asia ship with the language menu restricted to Japanese, Chinese, or Korean regardless of what you select. If your Language option only shows Asian languages and you need English, the device may have been sold in a market where English wasn't offered as an option. In those cases, the only real fix is a firmware flash, which means finding a compatible firmware file from a unit sold in a different region. That's a gray-area process. Sanyo doesn't support it, and bricking the unit is a real risk if you pick the wrong file. I've done it successfully on a couple of units, but I wouldn't recommend it as a first step. If you're working with a Sanyo Gorilla signage display rather than a projector, the process is similar but the menu structure tends to be more basic. Language is usually in the System Settings section, and some models let you set the default language through a hidden service menu accessed by holding a specific button combo during power-on. The exact combo varies by model year, so checking the service manual for your specific unit is worth the effort before you start pressing random button combinations.

A Few Things to Keep in Mind
The whole process usually takes between five and fifteen minutes if you have the manual on hand. Without it, factor in another twenty to thirty minutes for photo-matching and hunting down the right documentation. If you're dealing with a region-locked unit and need English, budget a few hours at minimum, and even then success isn't guaranteed. Also, firmware updates can reset your language choice back to the default for your region. If you recently updated the firmware and the language changed again, you'll need to go through the process a second time. I've seen this happen at least once on every Gorilla model I've worked on, so it's not unusual.
