The key here is the click you heard before the blue went full on. That was probably an arc which was probably either an internal arc of the tube which could indicate a bad tube, or an arc that took out the CRT card. Since it's on full, consistently then is more likely the card.
Whats up with the red?

The problem now is you seem to afraid to touch anything so suggestions seem fruitless.

When I put the CPU board back in after changing the battery , the remote showed auto start. Since the this new symptom with the over current the power button has to be pressed before it comes on.
I/m so confused.

The blue appears to be a new problem, possibly just moveig dust around while working on it and the dust could cause an arc. very rare but could explain your blue problem.
Your CPU appears to be minor, just a matter of getting settings back to where they should be. The red we are not sure yet.
But you need the balls to do what is suggested.

There is a little dust inside but not a great deal.
School tomorrow night so:
Wed night I'll try swapping the neck board with the green and see if the problem follows it.
As you say there is still the scan lines on the red with the red shut down.
Thanks

Are scan lines with the red turned off also a symptom of dead neck board? Just curious if I'm looking for 2 dead neck boards and if so did I do something changing the battery to bring this on.If this seems likely ,I should get another CPU board and a set of neck boards tracked down.

Did someone say try turning down the G2 first to verify?

That describes my G2 settings on my Ampro 4000 to a 'T'

Ya know, those National rifle association guys were right. If I had a pistol...............wait a minute, I do 
Now loosen the clamp on the blue neck board and slide it on and off the tube a couple of times to clean the pins.
Then tighten the clamp and try again.
Also check the video leads from the RGB1 board that go to each neck board. Make sure they are securly connected.
I have trunk monkeys and I'm not afraid to use them.

I will do that tomorrow night.

What is G2; keeping in mind that no adjustments can be made from the remote at this time, as soon as the pj comes to life I have about 2 seconds of blue then off and "high beam current"

You're a genius. The neck board has 3 white flat components about an inch square up the edge of the board. Each of these is divided into 3 strips. I don't recognize these components but I suspect that it doesn't work well without them. The jiggling of removing and replacing the neck board resulted in a piece of the middle one landing in my hair. I suspect these are resistors in a voltage divider and are that shape to dissipate heat. They probably get crispy with age. Regardless I guess I need a new on or three. The red neck board is a different layout. Curt??? How are you fixed for boards?
WTF is G2?

The red neck card is just reversed to the other two have a second look you will see what I mean, I think it fits into the chassis better that way so the tube can swing fully, Chip Scott or Ron would know better.
G2 is the red knob on the neckcard as you turn it the g2 goes up or down, you have to do this with the pj on , you need to have this correct or getting a good picture is going to be impossible unless it was correctly set before you got the pj. The procedure is in the manual I think.

Yes I see it. Thank you. My theory at this time is that I should have taken "Stefuel's" advice and asked Curt to replace my battery for me and that I've slopped a wee gob of solder somewhere that it shouldn't be. This has damaged at least 2 of my neck boards. My apologies for not being as good a listener as I should be.
So ... If I can I'll buy some new boards from Curt and start over with setting up. The manual is organized in an odd manner and takes a little getting used to. If you run across the set up for G2 would you be so kind as to pass along the page #?
Thanks

Those flat white things are resistors. Send me both boards, I'll fix them as I'm getting low on spares.

You sure are getting low on spares Curt I am taking them lol! dont forget me, I cannot see a page reffering to G2 so maybe I imagined it or its in the something else but the link I sent you should sort you out with what you have to do.

The click I heard was probably the resistor cracking.
Thanks Curt. I'll get them off to you as soon as I can.

I love this forum, you cant pay for support or experience like this, priceless, I think I saw the G2 in the setup menu, with my memory who knows though!

I don't think I ever have seen one of those resistors go. If It is what I think you are talking about they are all the same 180 ohm 10 watt resistors. It's more likely you damaged it moving the neckboard or when you were working on the CPU.
You must treat these with care little grasshopper.

The boards are back and in.... thanks Curt
The lines on the red face are still there: horizontal and diagonal. G2 sounds like something to look at and I will when I get that far. I'm not very focused right now, you know how life gets in the way of fun sometimes. Anyway the red lines weren't a problem until the battery died and neither was the cracked resistor on the blue neck board. I like it loud sometimes and I wonder if maybe the Ampro doesn't. By loud I mean my SPL meter gives up at 125. I'm using some old Altec speakers and the drywall in every part of the room feels like your touching a speaker cone when the mood is right for LOUD.
Anyway : red lines????? Oh and auto-restart is back to random. Not a problem from a use point of view , just offering as a possible symptom.
Thanks

What boards were repaired?
Turn down the G2 on the red and see if the lines go away. If not then I need a picture to see what your talking about.
