danlee Posted August 3, 2019 Share Posted August 3, 2019 It hapened recently, after plugging in the jack cable in the JTV, the model selector won't get activated after pushing it. Guitar stays in pick up mode. Battery indicates 4 green lights. It works again after putting the battery out and back in. Small thing but it could get worse. Any ideas? Thanks!!

psarkissian Posted August 5, 2019 Share Posted August 5, 2019 -Battery contact -Battery box power management circuit -Loose connector inside -Loose connector outside -Circuit board glitch -Not using a 1/4" cable with a Tip/Ring/Sleeve plug -If it's a JTV-69,... a loose retainer nut under the volume and/or tone control can result in an intermittent chassis ground, and can effect a number of functions, including Model engagement. It should be troubleshooted by a Line 6 authorized service center. Quote Link to comment Share on other sites More sharing options...
Thark Posted August 16, 2019 Share Posted August 16, 2019 I seem to recall something mentioned somewhere about the selector switch. The thing was that when pushed extra hard the knob moves down the shaft a bit and then won't work properly. The fix, as I recall, is to pull the selector knob off and put a shim in it to raise it up enough so that it engages the switch mechanism. Sorry, I can't remember where I saw this but it may be worth a try in your case. Quote Link to comment Share on other sites More sharing options...
