SOURCE: Video will not turn off; "I2C-BUS STOP MODE" error at power up

Nope a very easy problem .. What it is is the relay is stuck on or closed so when you plug in the set the power comes up But the micro hasent told the rest of the set to work yet. So when you hit the power button. its just like you hit the power and it activated the relay and the rest of the set. Now in some rare occasions the driver transistor for the relay was shorted But most of the time its the contacts that weild shut, but you cant just clean them as it will work for a while, but in a month or so you will be in the smame boat. But if you not a tech this repair shouldnt cost you to much because if your not an experienced tech you can not only cause harn to the set but also you yourself BE CAREFULL and take the set to a pro!!!! Good Luck

,,always unplug the set from AC,leave off a few minutes,,then re-plug back in,,that resets the micro--also,it could be the volume up button stuck-that would kill the other keys from working--you could try with a tooth pick to pull VOL UP back----THIS IS DANGEROUS --SHOCK HAZZARD!!! if someone is technically incline,with the back of the tv off,,turn set on and unplug the keyboard plug from the main circuit board while the set is playing--then use the remote and see if the fuctions returned-THIS IS DANGEROUS-SHOCK HAZARD---I REPEAT -DANGEROUS!!!! PLEASE BE CARFULL,if that cures the problem-you have a bad keyboard-you can just leave it unplugged and use the remote----JUST BE CARFULLLLLLL

SOURCE: TV powers on and then cannot change channel or change volume???

The fault may be the control panel, or it may be in the uPC itself.

Most of the time, it is some of the switches on the control panel.

The most common cause of this type of failure is that many times when people clean the TV set, they spray cleaner directly on the screen or the set. The liquid runs down in to the set and causes damage. Sometimes the damage can be very expensive!

If the fault is just the control panel board, this can be easily replaced. You can order one from the manufacture's parts department or from one of their parts distributors.

You will need the service manual, a scope, and a DVM to troubleshoot the problem if it is more involved than just changing the panel. The only way to know is to try the panel unless you have a way to test it.

SOURCE: JVC TV LT-32G80BU can't navigate in menu + all channels messed up

TV seems to reset it's settings for some reason (it happened to me with similar TV - LT-32A80SU). I have found the way to solve this situation - service menu.

Press button "i" and "mute" on remote at the same time - service menu should appear. Now press 8 and there should be menu that allows to change few advanced features. Pressing down and up arrows allows to navigate, pressing right and left arrows changes values. You have to change "dual HDMI" to YES (this will enable second HDMI port) and change "remocon" to other option available (this will change how the remote behaves). Save settings by pressing OK button. Now you can leave service menu by pressing "i" button twice. You should now be able to use your TV like before.

Remember - these are instructions for my TV and they worked for me but playing with service menu can be dangerous so you're doing it at your own risk. Ask JVS support if you're not sure what to do.

Sylvania tv without remote video channel


Volume up button (turns it on) so does channel up,
Input select is under the front panel of the Screen, and channels wont work anyway cause analogue signals is no longer broadcasting anymore so you wont receive a station without a set top box.

With the JVC D-series TV do you need a Remote Control to turn on the input screen?


No. Almost all TVs can be turned on manually.

However, those of us who are TRUE couch potatoes would NEVER rise from our seated positions to do ANYTHING manually when there are remotes that allow one to do the same thing from a comfortable distance!!!

If you look on the right side or across the bottom front of the unit, you will see the various buttons for power-on, volume, channel selections, etc....

Blue light


Okay, I found a fix! Called JVC, spoke to somebody there, here it is:
1)unplug the TV completely, no wall no power strips, completely
2)wait 10 sec
3)plug TV back in and Turn it on, the light will still be doing the same thing
4)wait 30 sec
5)ON THE TV, not the remote, locate the menu, volume (-) and power button.
6)while simultaneously holding down the menu and volume (-) button, pressed the power button ONCE and continue to hold the other 2 for 10 sec.
7)on the remote control, go to menu>settings>system info
*** now this I know as a FACT will work on systems that display: JVC - ver.5.32FO001, but I don't know of any other versions***
8)press the mute button on the remote twice
9)unplugg TV again and wait 10 sec.
10) plug TV in and turn on

It SHOULD be working normally now... Thanx to the guys a JVC support for this one, I know it seems like an obvious first place to look, but sometimes it isn't. I for one checked online forums first.

Tv turns on manually, but auto flips through channels and you can't use remote


Found this in another forum (www.hometheaterspot.com) and it fixed my remote problem:

"...it's possible that one of the front panel buttons is "stuck" or shorted, and this could cause the TV to ignore commands from the front panel or remote. But this should also cause the Power command to be ignored, too. You might try pulling off the front panel and disconnecting the front panel buttons and then see if the remote works."
