Question about JVC AV-32260 32" TV

1 Answer

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

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

Tv is going into x-ray protection mode. Check power supply voltage, make sure it's not too high. 160v dc across main cap, do not use chassis ground, use cap ground. If too high, something is open. If too low, something is shorted in power supply. Check voltage regulator ic.

Closed caption
Manual Library you should find all you need here:

Just word search the manual for closed caption


if you can find this in your TV options I cut and pasted it from the manual, see the line with Closed caption settings see if yours matches, sorry about the formatting this furm post will not cut and paste properlyeach of the #'s below corosponds to the bold headings.

I also found this with the word search but it makes no sense to me sorry...

The HDR2002 has two microprocessors. The Microprocessor, 7001, on the SSB monitors the Keyboard and the Remote sensor during standby. This IC controls the Tuner, Video switching on the SSB, generates the consumer OSD. Pin 5 of 7001 monitors the Keyboard for a voltage change to generate a command. The Front Detect line on Pin 6 monitors the AV inputs on the Side Jack panel. If a problem develops, the Front Detect will go Low, preventing 7001 from receiving any commands. The Power Fail input on Pin 79 goes High if the set looses power while the set is On. Composite Video is fed to Pin 31 for Closed Caption decoding. Horizontal and Vertical sync on Pins 53 and 55 synchronize the OSD and Closed Captions display signals, which are output on Pins 46, 47, and 48. Fast Blanking for the OSD is output on Pin 52 There are three I2C busses on 7001. The Bus on Pins 78, 80, and 97 communicates with the MemoryIC 7012. This IC stores Customer setup information, Option codes, and Error codes. I2C busses, Sand F communicate with the Tuner on the PIP panel, and the ICs on the SSB. The S bus also controlsthe Tuner on the SSM and the Audio and Video switching on the SSM. Data lines on Pins 16 and 17communicate with the Microprocessor on the ACS module.

below is my general post about this TV, I'm not sure if any of its info will help but there are links to other info on this TV set... Good luck
