Question about Parasound HCA-2205AT 5-Channel Amplifier

1 Answer

I have an overload indicator on channel 2. I opened the lid and swapped the channel 2 module with the channel 5 module and the overload light followed the card and showed up on channel 5. Parasound said the parts are in warranty, but the labor is 100/hr. Any thoughts on what might have gone bad?

I believe that the output transistors may be bad. Without seeing the actual card, there is no way to tell. If the parts are under warranty, request a replacement board. If I remember correctly, the board is the field replaceable unit (smallest orderable part) anyway. If not, you will need instruction from Parasound about what to do next.

In my JVC RX 8SD only works a channel. How do I repair this defect?


Start with the simple things.
  • Check left right balance
  • Swap output speakers left to right
  • Swap the speakers at the receiver to make sure no wire open/short
  • Swap input RCA cables left to right red/white - white/red
Ok No JOY!
JVC has thermal overload circuits/overload on most of there Amps.

Remove power for a minute or two to see if there is a reset.

Rewire speaker connections to speaker set 2.

Connect REC out to Rec In swap cables and see if problem is in pre-amp or power amp.

Check internal fuses.

Amp light not working and one dead right channel


Without knowing how it's actually laid out, I'd surmise the output amplifier transistors in the right channel are shorted, the fuse for that channel may be blown, and the speaker protection circuit is keeping it turned off. Most amplifier speaker protectors disable both channels if there is a problem, but yours could be different. I surmise the lights you mention are directly connected to the speaker protector chips and indicate readiness for normal operation. If it takes a few seconds for them to come on after power-up, that lends credence to my hypothesis.
Unplug the amplifier, open it up, and measure the resistance from the right channel output to each of the output power supplies (or to the fuse for the output power supply for that channel, if present). If one or both is very low (i. e, close to zero), you have a fried transistor. If that is the case, it is probably a good idea to replace the complementary transistor connecting the speaker to the other power supply even if it tests good; it may have been overloaded when the first one shorted. In many amplifiers, the transistors are inside a hybrid amplifier module, so you would have to replace the entire module. In some amps, you have multiple transistors in parallel; here you can probably keep the transistors that were in parallel with the failed unit, but I'd still recommend changing the complementary transistors.

That is Error code 49,
49. (00110001) Phase 2 to 6 - Cold Valve Faulty (proportional)
The Motor Controller module has measured a voltage from the valve diagnostic
circuit that indicates the cold valve is faulty. The most likely cause is that the valve
harness has not been connected correctly or the valve is open circuit. See fault code 48 for service procedure.
48. (00110000) Phase 2 to 6 - Hot and Cold Valve Faulty
The Motor Controller module has measured voltages from the valve diagnostic
circuit that indicate both the hot and cold valves are faulty. The most likely cause is
that the valve harnesses have not been connected correctly or the valve is open
circuit.
Primary Source: Wiring.
Action:
Check the valve harnesses are correctly fastened to the valves or the pins are not
bent backwards.
Secondary Source: Water Valves.
Action:
Check the valve coils are not faulty (open circuit).
Tertiary Source: Motor Controller module.
Action:
Replace the Motor Controller module.

One channel thermal overload stays lit and no output from that channel. even after unit sits overnight, thermal light on immediately,unit not hot. Looking for schematic?


Red light is on if:
- thermal protection, overheated amp, bad thermo sensor
- DC at speaker terminals
- high current at output transistors
Also could be a protection circuit malfunction.
In any case you need new channel module or send your module or whole amp for repair here.
Thanks,

DTC 002
The transfer case encoder motor is an assembly which houses four separate channels. These channels are used to indicate to the transfer case shift control module the present gear position of the transfer case or if the transfer case is in transition between gears. The encoder motor assembly consists of an electronically conductive inner ground ring in contact with a three legged wiper arm. Each leg's length is such that it makes contact with the conductive regions of the four channels. When any leg of the wiper arm is making contact with the conductive area of any channel, the encoder provides a path to ground to the inner ground ring.
During electronic shifting, the transfer case shift control module monitors the transfer case encoder circuit for the proper operating sequence. If at any time during a shift, the encoder changes from one position to any position other than the next possible position, an error counter in the transfer case shift control module increments by four. After the counter reaches 32, the transfer case shift control module set a DTC 2, a permanent "encoder fault," and reverts to a 2HI to 4LO or a 4LO to 2HI shift pattern only. To guard against a transient, random encoder fault due to vibration, dirt, electrical noise, etc., the fault counter reduces by one each time the transfer case shift control module detects a valid encoder value. The encoder must intermittently fail 25 percent of the time for the transfer case shift control module to consider it faulty and store DTC 2.

This is from Ken on CarPros:
Here is the way to reset the security system.

https://www.2carpros.com/articles/how-to-reset-a-security-system

Here is the systems descriptions

There are 2 security system, namely anti-theft and immobilizer.

Here are the 2 systems.

DESCRIPTION & OPERATION
Anti-theft system is controlled by Body Control Module (BCM). BCM receives signals from hood switch, trunk switch, door switches and Local Control Modules (LCMs). There are 5 LCMs located throughout vehicle.

To set anti-theft system in armed mode, remove ignition key, close all doors, trunk and hood. Lock doors using key or remote controller. The SECURITY light will illuminate for 30 seconds, then flash in 2.4 second intervals, indicating system is in armed mode.

To cancel armed mode, unlock and open any door or trunk lid using key or remote controller. SECURITY light will flash every second, indicating system is disarmed.

Alarm will activate (horn sounds, headlights flash and starter circuit is disabled) if any of the following conditions occur while system is in armed mode:

Engine hood or trunk lid is opened using the hood or trunk lid release.
Door(s) is unlocked without key or remote controller.
Tampering with any door/trunk lid key cylinders.
To deactivate anti-theft system, unlock door or trunk using key or remote controller.

If it is the immobilizer that is preventing the engine from being started, ensure you have the correct key and the transponder is intact. Quite often keys are dropped and if it breaks open, the internals would scatter all over. When this occurs, there is a tendency for the transponder to be lost.

Please let us know happens so it will help others.

Best, Ken
I hope that helps you out!

No sound from centre speaker on my Bose Lifestyle 8 series 2 system. I've checked leads and speakers by swapping them around. If it is the Acoustimass module which units are compatible?


Check your audio settings, via the on-screen menu. The center channel may be turned down. When set at -5 to -8, the center channel speaker may be practically inaudible. If raising the volume of the center channel does not solve the problem, then you do have a dead center channel. The system would then be in need of repair.

Philips universal remote codes


Hi Troysingleto. The code can depend on what model of URC you have. According to a site I found by Googling, the code for Apex TVs on one common URC from Philips is 044. Here are the steps to input it directly:

1. Press and hold the Code Search button until the red indicator stays on. Release the Code Search button.

2. Press and release the desired mode button (TV, DVD, etc). The red indicator blinks, then stays lit.

3. Enter the 3 digit code (044) . Note: after a valid code entry, the red indicator turns off. For an invalid code, the red indicator flashes.

4. With your device on, press CHANNEL Up. If the device responds, no further programming is required. Note: If some buttons do not operate your equipment, try one of the other codes for your brand.


If that code does not work, you can still find the code using this manual procedure first posted on FixYa by cptnkirk4064:

1. Manually turn on device to be controlled.

2. Press and hold the "Code Search" button until the red indicator light stays on, then release it.

3. Press and quickly release the desired code button (TV, VCR, etc). The red indicator light should blink once.

4.Press the "Channel Up" button repeatedly (up to 300 times) until thedevice to be controlled changes channel. The red indicator light shouldblink off with each button press. If you accidentally overshoot therequired code, press the "Channel Down" button to backtrack through thelibrary until the device changes channel. Pressing "Channel Up" changesdirection again.

5. Press and release "Mute" button to install the code.


If you wish to actually identify the code once this has been done, this is the procedure:

1. Press and hold the "Code Search" button until the red indicator stays on. Release the "Code Search" button.

2. Press and release the desired mode button (TV, VCR, etc.). The red indicator light blinks and then stays on.

3. Press and release the "Code Search" button. The red indicator light goes off.

4.To find the first digit for the code stored under the mode key pressedin "Step 2" press each numeric key from 1-9 in turn. When the redindicator light blinks off, the number you pressed is the first digitfor the code you are searching for.

5. To find the second digit,repeat "Step 4," this time when the red indicator light blinks off,this is the second digit in your number.

6. Repeat again for the third digit in your code number.



Once I find out the code for my TV or DVD player, I write it on a small piece of paper (make sure to note which unit code is for!) and tape it to the inside of the lid to the battery compartment for future reference.

Best of luck!
