How do I fix DC peak (IPM fault) On lg ductless inverter outside unit


This fault is caused by an over current in the inverters DC power circuit. If the DC part of the circuit exceeds 14 Amps fault code 21 will be displayed. This is caused by either the inverter PCB being faulty or compressor being short circuit or grounded. Disconnect the electrical connections to the compressor and check the resistance of the compressor windings, measure from U to V, V to W and W to U the values should be between 0.25 and 5 Ohms each.
The next test is to measure the resistance of the compressor windings to earth. Using a Megger (High Voltage Meter) measure the resistance from any of the 3 compressor terminals to an Earth point (pipe work). The value should exceed 2 M Ohms.
If the compressors fail these tests it will need replacing. If the compressor is OK... CHANGE THE PCB

I don't have a remote for my panasonic sa-xr25. Can I turn off the surround/enhanced button from the receiver?


Get your reading glasses out. There's a button marked "Enhance Surround" two clicks to the left of the Volume Control.

The sound is distorted and overwhelmed by static


Depends what the real problem is.

Is it related to certain sources only - try new or reseated cables,swap it to a different input; single channel - swap to isolate; or certain controls that have become noisy? A shop might be able to get some tuner cleaner into them.

Looking for a new Panasonic SA-XR25 6.1 Channels


A quick search only revealed on online retailer that still had one in stock:
http://abcdealz.stores.yahoo.net/pansarx25.html

I strongly suggest calling them to verify that the unit is in stock prior to placing the order online.

Alternatively, set up a saved-search on ebay to alert you if one is posted, or post to "Want it now". (http://pages.ebay.com/wantitnow/index.html)

I suspect the unit is still under warranty. Call Panasonic to verify:

Resister burnt


Guest and Lesfix. RU83 located on the DRC8335 VCR PCB is a 51ohm 1/4 watt 5% tolerence resistor, color coded green-brown-black-gold. As to zener diode DU83, I haven't been able to determine it's value yet but am working on the problem.

Be aware when either or both these components fry, this indicates you need to replace the following two overheating capacitors on the power-supply board, which were directly resonsibile for knocking them out:

• C216 1000µf 16 volt (upgrade to 35 volts)
• C218 1000µf 10 volt (upgrade to 35 volts)

Could you email me regarding this problem when you have time. Mention Fixya and DU83 in the subject line so I realize it's from you. Thanks. mikeadams110@yahoo.com

Receiver has lost audio


There are four surface mounted caps, 22uf/10v under the surround processor PCB on the main PCB.
Just replace them all.
That took care of my static problem.
