Where is the air filter on this tv ?? it keeps saying it needs cleaning and shuts itself down after 1 min. ? this is the first time this has happened in 5 years !


the filter is located internal to the unit and you must dissemble your unit to clean or replace it this is not as a user serviceable item on some units, contact Panasonic via there web sight and request information from there tech services for further info.

Hello, i will list the criteria required to service TV and projector TV`s first and foremost you require a good understanding of how TV`s work and the ability of reading schematic diagrams, then you require a knowledge of how printed circuit boards are patterned so you can navigate around them to locate possible trouble spots.
then you require
1 multie meter of good quality
1 oscilloscope 20 MHz or better
1 shop service manual pertinent to your type and model of unit you wish to repair
this is a minimum requirement of test equipment you can have

you also kneed a location or locations to obtain the replacement parts you may require to complete the service task.
Now if you have all the above criteria in place then you have some hope to service your unit

a flashing red indicator on your TV usually refers to an internal circuit failure, most modern TV`s have circuits incorporated in the circuit design to protect good working components not involved in the fault from further damage so the set will not power up and an indicator light will start flashing, trouble spots can be anything like power supply under voltage, over voltage over current, no vertical deflection, excessive high voltage, XRAY, convergence failure,, EXT EXT,EXT,
Warning rear projection televisions can harbor in excess of 30,000 ,yes that is thousand Volts

There are and never will be user serviceable components inside LOL

Now if you are ready and require further assistance you may contact me and i will step you through the diagnostic procedures Good luck

I have a panasonic 56 that the red light stays solid red for five seconds, then blinks five times when turned on. No pic, no sound.


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.

Thanks for using FixYa

crsheidt,
I am having the same problem.Terryfic gave me some good advice I am the process of taking. The service manual will help you locate the convergence IC circuit board so you can remove it to replace the IC`s. If you need I can send you a copy of the location picture from the service manual.I recommend you contact Terryfic for exact advice.

Hello,
You can search this database for the service info you seek about your tv here:
http://www.samswebsite.com/photofacts.html

Most service manuals with schematics cost about $27.95 for the PDF version of it, otherwise the paper version is about $15.00 more for handling and shipping.

You will need the chassis number of the unit in question in order to search for it. I hope this helps!

Good Luck!
