Question about Harman Kardon Harman Multimedia TC-30 LCD Remote Control
Hello, I've got a HK receiver/ amplifier avr 5550 with original remote control. Somehow i can just use the remote when i am standing 1 meter away from the receiver! so i cant use it sitting on the couch. I allso have an HK DVD player wich i can controll with the same remote and this works perfectly even from 5 metres. So the problem seems to be in the receiver/amplifier. can you tell me if this can be fixed? I am a technical person so i can replace parts myself but i have to know what part and where to find it
a 6ya expert can help you resolve that issue over the phone in a minute or two.

a) Place the two remotes so that their IR transmitters face each other
end to end, separated by about one inch. The
AVR 354 remote’s transmitter also serves as an IR receiver during
the learning process.– AVR 354 and Original Remote Head-to-Head
b) Press the Source Selector for the device mode you wish to learn
a code into, and place the AVR 354 remote in Learning mode by
pressing and holding the Learn Button until the Source Selector lights
up, then release.
Learning Remote Commands
c) Press the button on the AVR 350 remote you wish to program with
the new code, and the Source Selector will flash once. You may
learn a new code into the following buttons: Device Power On/Off,
Alphanumeric Keys, Last Button, Back/Exit Button, Menu Button, Navigation Buttons, OK Button, Disc Menu Button,
the four Teletext Buttons, Channel Up/Down, Volume Up/Down,
Mute and the Transport Controls (including Record).
d) Press and hold the button on the device’s original remote whose
code you wish to “learn” until the Source Selector flashes three
times, then release.
e) You may program additional buttons by repeating steps c) and d).
Press the Learn Button once to exit Learning mode, or wait for the
remote to “time out” and exit Learning mode on its own after about

SOURCE: power on but nothing else
My DVD22 did exactly the same. The solution mentioned by shelompidid not apply to me since my model already had the fix factory fitted.
The other problem mentioned on page 21 of the service manual did the trick for me, although the complaint does not seem to be directly relavant:
"Complaint: Will Not Read Disc; Other Functions May Be Disabled
See h/k service bulletins HK2004-03 and HK2005-02, as the issues covered there involve similar
Probable Cause: EC19 and EC20 (1000μf 16v capacitors) may be defective in the power supply. This can be checked by measuring the +3.3v and +5v voltages that are associated with EC19, 20 to see if they are low (more than 0.1v low). The SPMS output voltages are marked on the PCB adjacent to the large 13 pin header. While there is only one 3.3v pin, there are several +5v pins, and care should be taken to measure the correct one(s), which are either two +5v pins approximately in the center of the header.
I could actually see on the power supply board that these two caps were damaged, although they were not completely popped. An additional cap which was damaged on my board was EC4.
When I measured the voltages the middle D +5V was reading about 4,6V. I did not expect a problem until I read the statement above on page 21 stating it should not be low by more than 0,1V. My A+14 and A-14 voltages also read about +/-17 to +/-18V.
I replaced all three caps: EC4, EC19 and EC20 with 25V caps instead of 16V caps. The voltage for D +5V now read exactly 5,01V! The A+/-14 read +/-16V (some improvement).
My unit is operating fine after replacing these 3 caps! I suspect that the damage to the caps could have been spikes on the AC suppy some stage, maybe due to lightning. Pretty amazing that only the power supply have damage and not the main pcb.

The problem is with the actual eltromechanical element on the volume control, my avr 300 does this as well and I'll let you know the secret to avoiding it. There are small indents on the volume control as you turn it, if you leave it half way between indents, it will periodically start reading volume changes, if you're lucky it will go down, if you're unlucky by the time you've noticed it act up your speakers are blown. When you change the volume, make sure the control rests in an indent and the problem will never crop up again. A simple solution if you're the only one that uses the receiver.

SOURCE: Install problems at AVR 142
ensure that you have the reciver connected to a display monitor e.g t.v. set, there you'l be able to make all the necessary ammendments.use the video out or use the HDMI out to connect to your t.v.
which speakers are using for the avr 142?

SOURCE: HK AVR-247 protect mode
This is an indication of an internal problem. Typically this is shorted output transistors. Expect a parts cost in the $25-$40 range for this repair.
