Six
blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis
function immediately. Check C515 & 516 and the jungle IC, IC206. Might be of faulty IC. Visit the site named 'Electro-help' for
more details. Click this link. View it in
"Timeslide" or "Flipcard" option, which can be selected
from the drop down box menu by the [Sidebar] tag, at the top left corner
of the display window. You can also

Power supply. Disassemble and be careful tv is not plugged in. Check capacitors on power supply for bulges on top. Replace but make sure u deenergize before removal by touching the two poles together. I use a small nail file
The problem is on the 'A' circuit board. It is the IC504.Or, it is a low voltage drop or a short. Replace the "A" board. It is the front board on your right when you are at the rear of the set when you remove the cover. Look it up on the net. PS Don't touch the chassis while it is on...HIGH VOLTAGE !!!
Low HV Shutdown: On the D Board. Check IC8004/pin 7 should be 7.4v. Check IC8006/pin 2 should be 2.5v if lower will trigger shutdown by causing pin 1 to turn on. Check IC8006/pin 3 reference voltage 2.2v. IC8006/pin 1 normally at 0v. If high turns D5007 ON which turns the latch circuit Q6532, Q6530, and Q6527 ON and turns the AC relay RY6501 OFF.
And NOTE: 6 blinks also can be Low B+ protection.
Unregulated 7.5 v from the power supply to 5v reg IC504 on the A Board. 5v to M Board Q2314
to CPU IC2300/pin 43. If 5v missing set will shutdown with 6 blinks.
SIX Blinks---No Horizontal (H STOP), no raster, goes to the blinking selfdiagnosis
function immediately. Check C515 & 516 and the jungle IC, IC206.
SEVEN Blinks---High voltage shutdown. The high voltage has exceeded 33k
and the unit goes immediately into safety shutdown. Check power supply
regulation and horizontal circuits.
