TV is actually a JVC AV-31BP6 (Chassis A48), but I couldn't find a forum for that model. When the TV is plugged in, it automatically powers itself up. Without a cable hookup, the screen displays static as expected, but with cable attached the TV powers up to a black screen with the words "I2C-BUS STOP MODE" flashing at the bottom. Pressing the power button clears the text and brings the TV for all intents and purposes to normal functionality (picture is normal, channels change, volume control, menus, etc). When the power button is pressed either on the remote or from the front control panel, the audio shuts off as well as the channel display text, but the video continues to play. Pressing the power button again causes the screen to flash briefly before sound and channel display text return and the TV again resumes full function. Only removing the power plug will turn off the video. I have some small experience with TV repair but I'm not sure where to start with this and would greatly appreciate some advice. Is it likely that the I2C MCU is the culprit? Or should I be looking somewhere else? If so, where? Thanks in advance.
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
