finally had time/reason to figure out/use the bk 490. I had a 19" k7000 with a really weak picture. I read the manual, watched a few videos and gave it a shot. dig out adapter 31 and find its info in the book.
All the setup went fine. I set it to test, 2 of the 3 were in the bad. So I put it to rejuvenate and hit the button. thats where I have a question..
On the 1st gun, the meter only fell a little bit, but never went down to .5. So after about 10 seconds, I released it. No shorts. Went to test and it balanced out to good
Tried it on the 2nd gun, same thing. Never got to .5. No shorts. Went to test and it was good.
3rd gun it did go to .5 within 10 seconds. No shorts. back at test it was in good range.
Set the tracking and all was good.
Hit the life button and tube is good.
focus light said ok.
Put the neckboard back on and fired it up and it has a fantastic picture!My question is, is not getting to .5 with the rejuvination button normal? How long would you say is too long to hold down the rejuvenation button on each gun?
I wanted to try it again before I use the bk490 on an xy monitor.. I had some bad pac burned 4600 and a g07 so I thought perfect to try it on them. Thats where things start to get me really confused..
4600 put on adapter 23. Go to setup and I am not sure if it was in setup or in set cutoff or when I put it into test, I can see Kr, Kg,Kb and HTR are all very faintly flickering. So I see in the online notes for bk480-490 it says "h-k leakage cannot be repaired; use isolation transformer." That got me confused. Not sure what that means.
In the bk490 manual it says if the leakage is light, it can be ignored. So I decided to keep going and tried rejuvenate the gun and when I did the HTR light came on bright. So I stopped..
So next I pulled out the g07. Go through setup and this time when I get to set cutoff, I get no response from any of g2 controls. I switch the switch to high, and then get the meters to move. Now here is another question. Once I set g2 levels, should I move the switch back to normal before I got to test or leave it in high?
In the g2 high position, I go to test. all 3 of the guns read as bad. So I go to rejuvenate them and they again don't go .5. I finish the procedures and according to the meters, the tube is probably weak/bad (I did not hook up the g07 to see what the picture actually looks like).
So I am wondering if my bk 490 needs adjusting? Could the 23 adapter be bad? I am a bit puzzled right now on using this device. I don't know if it makes a difference, but the 4900 and the g07 were stored in a cold shed and its been really cold for the last few weeks..
