The 5 blinks on a Panasonic projection television set is usually a problem in the power supply to the high voltage circuits.

You should be able to get a local service center to repair this at your house for between $350.00 - $450.00.
If you want to repair this set yourself, I have some instructions below that will be a help to you.
***** NOTE : You can get electrocuted and be hurt or cause death . You have been warned, be very careful when repairing any electronics. ****

If you are handy with a DVM you can check a couple of things with the power off and the set unplugged.

Check the Horizontal Output Transistor (HOT) Q551 for shorts. You may have to remove it from the circuit to test it completely. Also, check the Damper Diode and the horizontal drive transformer T501, this transformer can have ring cracks around the legs and cause the HOT to short.

The next step would be to check to see if you have 140 VDC on the collector of the HOT. If you don’t then you will need to start trouble shooting to find out where the 140 VDC was lost.

This can be a difficult repair, so I would suggest that you call a reputable service center to come and check out your set.

I hope this information allows you to resolve this issue.
If you need further assistance please comment to this post and I will try to help you further.
