So, I have a JVC HD-52G786 television that I love. It is a low profile, rear projection, HD-ILA, 52" beast that I bought for myself for the Superbowl two years ago.
When I got it, HDMI wasn't really mainstream yet, so I never had a chance to use the HDMI input that it has. About a year later, I finally got HDMI output on my cable box, but could not get it to work (I just got a green screen). After talking to the Comcast tech and scouring the Internet, I figured that it was a problem with the HDMI output on the cable box being bad. Oh well. So, a little bit later, I got a new laptop which also had an HDMI output on it. Excited to use the HDMI input on my TV, I plugged it in and yep, you guessed it, GREEN SCREEN! Ouch. At this point, I figured my HDMI board on the TV was dead and there was no way I would pay for JVC to fix it seeing as it was out of warranty. That appeared to be the end of HDMI for this TV, which was too bad to say the least.
Now, because I love technology so much, and I believe I was bored at the time... a couple of weeks ago I started searching to see if the green screen issue was common place. It was. Then, I started to search on if it was common in JVC TVs. It was. Wow! I started looking up JVC TVs in my series and good god, I found some great info.
Apparently, because HDMI was so new when this TV came out and had so many bugs (remember USB 1.0?), JVC built in a secret way to reset it. Genius! Of course, JVC won't tell you how to do it, says you need a special maintenance remote, etc... Just trying to get you to pay for service. But, people being as smart as they are, someone (Cesar Maciel as far as I can tell) found a way to do it yourself. I just did it and everything is working perfectly! I have outlined the steps below, mostly so that I will know where to look the next time I need to do it. Woo Hoo!!!!
- Turn on TV
- Make sure the remote toggle switches are set to "TV" and "VCR" respectively
- Press the "Sleep" button
- Simultaneously press "Display" and "Video Status"
- Press "2" (Self Check)
- Turn off the TV
- Wait for fan to turn off (30 seconds or so)
- Unplug TV
- Wait for 30 seconds
- Turn TV back on
It should be obvious, but you need to be using the JVC remote for the TV to do this...
There is no one place where I found all of this info, but most of it came from this page and the links found within.
