Remote stopped working. tried several different remotes, reprogrammed them, new batts ect... Problem appears to be w/ infrared receiver in set. What i the best way to fix this without calling in a pro?
Well finally after trying everything else short of replacing the ir port or hitting it with hammer. What I done was drill a whole in the IR port screen about the size of a pencil so I could look inside.Well low and behold the remote worked from that day on. i don't know if I shook something in place or or the ir port was blocking signal. Either way i'm glad it works.

Re: remote is inop
A universal remote is not a reliable way to test a remote control. If you can have an original remote this is the best way to test the remote function of the set. Or, if you have another set that is the same model as yours to test a universal remote, then the test would be acceptable.
If the remote has failed on the TV side, this can be from a number of problems in the set. It can be the remote IR sensor module itself, or one of the buffer amplifier stages on the way to the uPC, or the uPC itself. In some models the buffer amp is built in to the IR sensor module.
Without properly troubleshooting this fault, there is no possible way to actualy determine the point of failure. More than 90% of the time, the failure is the remote. Remotes get dropped, and abused often, and therefore they are subject to a high degree of failure.
Did you try unplugging the set from the AC mains for at least 15 to 20 seconds? This will cause a reset to occure for the uPC. If the fault is still there the set and the remote control will need a proper follow-up to service it.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

To confirmed if the remote control is working fine, aim the remote control sensor(IR emitter) directly to your cellphone camera. While pressing any button key on the remote control, you can see the flash of an infrared emitted by the remote control if it is working fine.
If you've confirmed that the remote control emitted an infrared but still the tv won't communicate with it, this is an indication of faulty IR sensor board of the TV. Check if there's an obstruction from the IR receiver in front. Keep away all of it, clean the plastic window of the IR receiver with soft clean cloth.
If the symptoms still persist, you have to replace the IR sensor board. Check the actual part no. of the board before ordering.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
The IR receiver in the TV may have gone out, but check the remote signal first. Testing remote control: The remote control puts out IR (InfraRed) signal that human eyes cannot see, to find out if the remote is sending out the signal or not you just point the remote at the digital camera’s Lens (Digital Camera can detect IR), you should see flashing light on the camera’s screen when any one of the remote button is pushed. If you do see the flashing on the camera, then the problem is in the TV IR receiver or the main logic board; more troubleshooting with scope will be needed to look at the signals.

I have the same plasma Pioneer tv. I also tried a replacement remote and no fix. I replaced the infrared receiver module (~$4 from Radio Shack) on the TV, yes it involved taking the tv apart. Voila, now I have two working remotes.
It sounds like the wall button has the lock feature engauged.
Is there a small green LED flashing inside the wall button?
Push and hold the lock button for about two seconds and the LED should stop flashing. This will unlock the garage door opener and your remotes should start working. You may have to reprogram your remotes and homelink again since you triedprograming in the lock mode.
You can try replacing the remote receiver inside the set. This should be a small silver box located in the front of hte set. It should have 3 leads soldered to the board. The part number is:
LSSZ0004 and costs about $5.
Based on your trying of different remotes, your conclusion is basically correct, however, it is very rare for the infrared receiver to go dead (or at least the sensor itself). Should this still be the case, there is no other way but to open the TV unit. Since the placement of the infrared receiver is to the front of the TV, chances are that what your are thinking "take the entire set apart." is the only way to do remove the infrared receiver.
A guess would be the sensor which normally is available even in RadioShack. Your best bet may be to seek the services of a qualified professional willing to undertake component level repair rather than modular/PCB replacement. At times it may just be a loose connection inside the TV or no low B+ to the infrared receiver module/circuitry.
Alternately, you can try to "borrow" an original remote and see if that will work just to really confirm. Some instances of this problem in some other brands/models got solved by resetting the TV (unplug for a couple of hours).
Hope this be of some idea/help. Pls post back how things turned up or should you need further information.
Good luck and kind regards.
