RGB chips cause problems, Q8121 on D board, dry joints on the processor or the processor itself, Q8805 (BUZ90 works) and or LOPTX, or either of the MCZ3001D chips or it may be as simple as dry joints on the field chip!

Good luck

Keith

The KV-32FX68U is AE-6B chassis and 4 led code the error message is "no vertical sync".

Probably opened resistors R8835 (0R47) R8834 (0R47).

Yes but,

Dead, flashing error code for no field synch. Misleading because there was no line drive due to L/Driver Tx T8802 being open circuit, therefore no line and no field.

One from the old TV mag files - Chris.

I have always found the auto diagnostic codes misleading. The faults I listed above can give any code, even unlisted codes, very useful. However, 4 flashes usually point to a vertical problem or something else!
I am sure Chrissie has it sorted, if he has a fork lift to move it!
