First it is not an emergency.
No Legitimate repair company should be that busy.
Call Hitachi and get an AUTHORIZED Hitachi dealer to service your TV.
Your problem is beyond self help/
Unplug the TV until it is repaired properly or you will do more damage and have a much larger repair bill.

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
