For manual
IIRC KV30HS420 was the common model with 2 IC's. Its SAMS 5162.
SAMS KV34..... models are 5429, 5398, 5460. No XBR's listed.
Try running on SAMS the chassis number SCC-### without varieties,
just the chassis family.
Only remember bad IC's & one or two FBT's on these sets. If the blink is for
over current its probably the FBT.
To test start the set a few times & see if the HOT is getting hot !
Another test is unplug the DGS, turn set on, watch the current.
If it goes over 1 amp usually FBT. Normal running current is @.8 amps.
And finally dont forget this has two or three grounds so gotta use the
right ground point for measurements.
