? I wounder what color is your lamp - red or yellow (amber) and just so you know most parts stores now days can tell what a code is with out charging a dime to you.

facing the back of the 7940 the top left corner is pin 16 the top right corner is pin 9. The bottom left is pin 8 and the bottom right is pin 1. Only a few of the 16 pins are used due to this unit only having pre-outs, no internal amplifier on this unit. Pin 1 red (ignition), Pin 2 pink/black (interrupt), Pin 3 orange (Illumination), Pin 8 black (ground), Pin 9 blue (power antenna), Pin 10 blue/white (remote turn on), Pin 16 yellow (battery).

Good Day;
It sounds like the TV may have a shorted CRT, picture tube, but let's trouble shoot:
1. Unplug TV from wall.
2. Remove speaker grill, two on bottom, the screws are covered with plastic caps, right and left side on bottom next to floor.
3. Remove inner panel.
4. The blue tube is the one the right side, remove socket, with phillips driver, make sure it's not touching anything.
5. Plug and turn TV back on, if picture appears with no blue it's the tube.
6. If still shuts down, bad blue CRT driver IC.
CAUTION: Call a factory authorized service dealer to give you an estimate, if this sounds too hard.
Good Luck, Day, Big Irish.

If you have a DIRECTV - push the reset on the Directv receiver.

Mine just did the same thing.  Except for it was green instead of blue.  The service manual states 8 flashes from the light stands for an overvoltage.  After reading the manual for a bit I realized the bottom row of 3 adjuster screws from behind the speaker grill adjust the output for the red, green, and blue colors.  BEFORE OPENING ANY TV OR MONITOR PLEASE KNOW THAT THE VOLTAGE INSIDE CAN KILL YOU EVEN IF UN-PLUGGED so please be careful and only adjust what is mentioned here.  I un-plugged the tv, removed the grill and the board covering the internals, and carefully turned the 3 adjustment screws all the way down.  I then waited about 10 minutes (don't know if this made a difference).  I turned on the tv, turned the channel to an auxilary input (for a black screen), and slowly raised each of the 3 bottom screws one by one up clockwise until i could see a faint green, blue, or red line (depending on the screw), and then turned each one back a hair until the screen was black again.  Only adjust one at a time, the order for colors are blue, green, then red from the left.  I hope this fixes your problems.  Be careful when working inside a tv,  I suggest not using a screw driver to adjust the screws due to the possibility of it slipping and someone getting hurt.
