| check the pico fuses on the power/deflection board. they may have opened up. |
| Is f883 open? It's a pico fuse. |

| Check the pico fuses in the power supply to see which one blew. |

| On a further note, I tested e994, e995, and e996 and they all came up with 0.00 on my ohm meter. I |

| OK
No idea what was wrong, ALL IS FINE AND WORKS AGAIN!
The problem was one of the pico fuses.
|
| E994 is a 2 amp pico fuse. |
| C707 is Hitachi part #0244211. #AZ00104M is the pico fuse.

| replace 2 convergence ics on d board and check 6 pico fuses.they are mounted on heat sincs near rear |
| ha..good luck finding a schematic for that...
either get a replacemant remote as minnie posted O |

| just replace 2 convergence ics(stk392-040).and check 2 pico fuses and all 3.9 ohm resistors. |
