So I went back threw my work and determined it was a under rated cap, So I went to my supplies of Caps and found a 1 x 250 and instead of a .47 x 50 so far so good as far as the filter popping....
Now I get a White raster with the faint outline of the game displaying. You really cant see it in a picture but it is there.
I will post a pic of what I have now.
I understand a LCD screen is an alternative, But I am determined to get this Tube going, No Burn what so ever.
I ask you to up the voltage on the cap in my pm. because i suspect the voltage is to
high.. the cap is in the Horizontal drive circuit off the Horiz-drive transistor and drive
transformer..
So now you need to check the B+ voltage..
Now if you look at the blue trim pot next to the Power supply
first look to see if it is already turned,I believe i notice paint or something
on it.
First set your meter for dc and now your going to search the secondary of
smps the output side for the highest voltage,keeping in mind the electrolytic cap
you replace that had a dc rating of 200-250v odds are this is the B+..line
measure the voltage first on the cathode of each diode..
and thinking about the dc on each diode record the voltages.
if you dont know which diodes im talking about then take a picture of it and
i can point out where they are...
Good notes will help you to understand and remember the over all voltages
are because when you turn the pot it may adjust just the Horiz-scan voltage
which mostly refered to as the B+ its mainly for the Horiz-circuits,like HOT
and fly and drive transformer...
the other taps of the smps are for a few other circuits like Drive Ics
and sync circuits..and mosfet's that are in the corner of the chassis
for differnet res-scanning..
Blindly turning the pot may not let you know what happening..
because you dont know what the voltages should be to begin with..
If you see the paint cracked it may have been turned and now you have a
over voltage issue..or if it wasn't turned then,we may have another issue
as always you want to make sure all your connections are good around the chassis.
Get the details about that and then i will tell you where your next problem
is with the over raster..as always the screen control screen should never be adjusted all the way
clockwise,as a test to see video you can turn it down to see if it was turn up to high..
again if the B+ is to high then the crt cathodes may have been effected as a result
and we can get to them after these other test are taken..on the neck board/
Proceedure will make a difference in you over all repair..
one step at a time..
I 'm still thinking of the chassis schematic or what the chassis is so when
i ask you for the flyback number i was going to check that more..
I'm not saying th fly is bad..
humer me and answer all my question's...
the next chassis your own your own what knowledge you get from this repair..
will help in many repair's that you know nothing about..
Don't think the cap that was blowing up was because the company put in the
the wrong voltage to begin with..its because you dc is to high..
What is the voltage on the cap that blew up now?
To much dc to the horiz drive circuit show up other issues later if it not correct.
Good Luck!
