Question about JVC AV-48WP30 48" Rear Projection Television
I have a red convergence issue with my av-48wp30. i see that there are numerous postings about bad stk392-110's......i replaced both and turned on the set only to find absolutely no change on my screen. after closer scrutinization, i noticed a smoked resistor, number r846.....which is marked 1.5 ohms (J)......after a trip to radio shack, i was unable to find a 1.5 ohm resistor.....anyone else have similar problems? where can i order one of these and what is the part number? also, how do i enter the service mode to adjust convergence? i know how to do it with the remote, is there another way? oh yeah, one more question.......what is the white button on the convergence board for?...thanks for any help!
1. if the 1.5 ohm resistor was open, then you may have fried your new convergence ic's. Sorry
2. bettween a 1.5 - 1.9 ohm resistor will work
3. press sleep button, set to 30
hold down video status button and press display on remote
select convergence from the new menu and hit OK.
Do fix the convergence before you try to align the convergence or it will look horrible after you get the circuit fixed and will be harder to align.
The white button is there because the DCU (digital convergence unit) can be erased by holding that button and turning the set on.
I WOULD NOT RECOMEND THAT AT ALL!!!!!!!!!!!
Hope this Helps.
