Question about Televison & Video
After power-on, get steady red light for about 5 seconds, then flashes 11 times, pauses, flashes 11 times etc.
Eventually starts up making a clattering sound like relays making intermittent contact.
Warrantee is up (1 year plus 12 month since purchase) so Panasonic tech says send in to local repair that will take weeks and hundreds of dollalrs.
I don't suppose there is a way, based on the flash code, to identify the bad circuit and specifically replace it without involving the certified geniuses? Thanks for your help ahead of time.
It was actually 1 year plus 1 month since purchase.
Anyway, the determination of the problem may be a little strong for those with weaker stomaches so here is fair warning that you don't need to read any further in this paragraph if you're one of those. After some detective work I found out that a teenage hellion temporarily living here had a fit of temper in which he had thrown some regurgitated chewing tobacco in saliva solution (in a plastic bottle) against the back wall behind my TV set, which then splashed into the vent slots in the back of the set, and then he carefully cleaned up the outside so that I wouldn't suspect anything.
Some of this "foreign matter" had gotten into the little venturi areas of the two little fans in the back, which would either hang up the spinning blades or keep them from spinning entirely unless they managed to break loose since they were in marginal contact with the obstruction.
I bought some "tuner cleaner" from Radio Shack and proceeded to take the back panel off (about 36 or so screws of two different sizes). I removed the two fans and sprayed and cleaned them out entirely, then put them back. Then to test it before reassembly I powered the set up. I immediately found that it exhibited exactly the same problem as before, namely the 11 flashes and no powering up. I then noticed that I had forgotten to re-hook the plug-in for one of the fans, and when I plugged it in, all has been well ever since.
So the moral of the story, the bottom line (in my case) is that if either of the fans has any sort of mechanical or electrical problem it will be sensed by the startup circuity and will likely keep your set from coming up. If there is any chance that your fan is either disconnected, obstructed, or the frame on it is bent or the bushing for the spinning part has partially seized up, you may be able to get function back by checking that you have two fans in good working order, possibly saving your self a ton of money and grief.

The front panel Status LED provides an indication of
the set's operation and the possible cause of a malfunction.
If an abnormal condition is indicated, perform the
Self Diagnostics procedure.
To activate, press the front panel <ACTIVITY> &<CH

The STATUS LED will then flash denoting a two digit
• The number of flashes indicates the value of the
MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2
• The LED then flashes indicating the value of the
(ones digit) of the Error Code.
• The Error Code is repeated a total of 5 times.
Example: If the Error Code is "23", the LED
will flash two times, pause, and then flash three

Error Codes, descriiptions and the most likely cause of
the error are listed in Table 2-3.
Note: The TV must be in "Shut Down." The LED
will probably be indicating an abnormal
condition. If the TV is switched Off, AC is
removed, or a System Reset is performed, the
code automatically resets to "12" No Error.
