Facing TV Problems? Ask a TV Technician.
Hi my name is***** tech for 30 years
When you are online post and I should be able to answer within a few minutes
Common sense on this one is that the TV was working before you replaced the STKs, pull the convergence winding plugs and see if the TV comes on, or open up the supply resistor to the ICs (removing the positive and negative voltages) from the ICs. The tv should come on with bad convergence indicating that the convergence ICs are somehow loading down the set into shutting down, try this and report please
what i mean by pull the windings is unplug the three convergence plugs , not the main yoke plugs
Ok it was something to try, some will power on even with these plugs disconnected.
some won't are the ICs still getting hot?
can you measure voltages?
Ok on the ICs what do you have on pin 11, 12, 13, 14 and 18?
with everything plugged in
oops and pin 17 too
no ground the black lead, set to DC voltage and measure the pins with the red lead of the voltmeter.
also tell me how many fuses you see , they are usually green shiny and look like resistors surrounding area of the ICs?
The hot one may be shorted,
one way to tell is swap the ICs and see if it gets hot in the other spot (alot of work)
I can not find a schematic for this model, but even without it. if you are getting those supply voltages
the fuses are probably OK.
Ok lets do that I will check in around 11am or so, thx
A diagram of the voltages for the power and convergence circuits might help.
I may not check back today, but upload what you have, Thx
