Ok, So there is still a problem with power supply voltages going up & Down...
Possible short, possible tube using too much current. Problem, current meter
does not measure above some unusable value....
Timmy you can make your current meter measure more current, but you gotta
make an adapter for it....
First, in the uploaded pic. Fig. 1 Just FYI this is the only way to measure DC
Current in any circuit. You have to cut the Current Path and insert the Current
Meter into the path.
Second, This is kinda experimental, Since you have 2 meters, you can select
one meter you want to use as your current meter for this tv. It needs to be
able to measure about 700ma max.
Fig. 2 shows the start of my experiment, Take your current meter - set it to
the current DC Scale you will be using, It needs to be the MAX Current, I believe
it was pretty low. If there is more than one DC Current scale, be aware you
will not be able to switch scales with this little mod...
Measure the resistance of the Amp-Meter set to the Current Scale you want to
use. Find this resistance, I believe it will be around 5 - 12 Ohms maybe less....
Find another resistor in your stash 1W or so, that is the same value. Put that
resistor across your current meter leads as in my Fig. 3 pic. This will
DOUBLE the range of your current meter in it's present scale, HOWEVER,
your meter will ACTUALLY be reading ONE HALF of the current passing
through it.... Remember Current in Parallel Resistors Divides according
to resistance..... So For Example, if your meter reads 10 Ohms, putting
a 10 Ohm resistor across the probes will give the measured current 2 Paths
One through the meter, and the other through the added resistor.....
Find the equation online to Add Multipliers to the meter's ability.... How?
5 Ohms in parallel with the current meter will 3X I Believe the meters range...
Once you build this circuit you will have to test it with known test circuit so
you know it's giving you somewhat accurate readings.....
Then, you can monitor current paths in this TV that may be using too much
Fossil Fuel generated electricity when you turn it off & back on and have all
those low voltage problems....
Hurry though, this blasted thread is approaching 50 pages.....
Good Luck....
