Well, in the service manual, there is no sequence of blinks mentioned that you are having. The closest sequence mentioned is with the TEMP LED blinking once every 5 seconds (maybe your TEMP LED is burned out?).
With that, this is what is mentioned in the manual:
"POWER LED flashes orange 5 times every 5 seconds.
TEMP LED flashes once every 5 seconds.
LAMP LED flashes once every 5 seconds ...
Abnormal Voltage on 33 V line of Main C.B.A.
Replace the Power C.B.A. Still No Good, replace the Main C.B.A. Still No Good, replace the Tuner C.B.A."
The service manual depends on board replacement, not component-level repair. So, it is difficult to determine what might be causing your error codes.
I had mentioned on another thread that it could be your lamp that is causing the problem. Possibly your TV circuitry is detecting abnormal voltages with your bulb; it could be drawing too much current to keep it lit because of its age. If it was temperature related, the temp light usually flashes instead.
Lamp replacement is iffy. Off-brand lamps, although less expensive, can be unreliable. And, the official Panasonic lamps still seem to be pricey but the most reliable. But since the price of similar sized LCDs and Plasmas have come down so much in price, it may be worthwhile to consider an upgrade instead.
