How to unlock to transfer to other channel

if you have indication of signal input for both channel you can go and reverse output cables of the speakers if the problem transfer to good channel change speaker cable-if you did not have input indication in the bad channel try to inverse input cable if it is cleared change your input cable if not you will have internal trouble and need service center to help.

Transfer Channel 2 speakers to Channel 1 to check if it does put out a sound. If it does, it means that your Channel 2 amplifier is defective. However, if it doesn't,
then your Channel 2 speaker is defective. So, have this checked to find out the result. Defective items needs replacement or be repaired. Send us your e-mail for the result so we can further extend our assistance.

Compaq Presario V V3000 Specification Memory Type: DDR2 SODIMM 200pin DDR SODIMM:
DDR, double data rate is a type of SDRAM in which data is sent on both the rising and falling edges of clock cycles in a data burst. It is usually referred to as DDR as opposed to DDR SDRAM.
SODIMM, small outline dual inline memory module. Smaller and thinner than standard DIMMs, SODIMMs are typically used in laptop computers. Memory Speed: PC2-4200, PC2-5300 Chipset: Intel 945GM Chipset :
A group of chips that together make up a complete computer processing unit, usually on one circuit board (the motherboard). It may include the main central processor, graphics processors, secondary cache memory, and input-output controllers. Memory is one component controlled by the chipset. Standard Memory: 512MB Removable Memory Slot(s): 2 Max. Memory Per System: 2048MB (2GB) Max. Memory Per Slot: 2048MB (2GB) Dual Channel Memory Support: Supported Dual Channel :
A development in motherboard and chipset design that allows for increased bandwidth transfer when using two or more memory modules in separate transfer channels. These separate channels allow each module access to the memory controller, increasing throughput bandwidth. It is a good idea to use matched pairs of modules to ensure the best compatibility for dual channel operation. Tri-Channel Memory Support: Not Support Tri-Channel :
A development in motherboard and chipset design that allows for increased bandwidth transfer when using three or more memory modules in separate transfer channels. These separate channels allow each module access to the memory controller, increasing throughput bandwidth. It is a good idea to use matched three modules to ensure the best compatibility for tri-channel operation. Install Memory in Pairs: Not Required Install in Pairs :
Memory modules must be installed in pairs of matched memory size. This means that if you purchased your computer with 128 MB of memory installed and you want to add another 512 MB of memory, you must remove the two continuity modules and replace them with two 256-MB memory modules.

You can download a software fix for it:

It's called resetdma.vbs ,download it and then install it.
The site also has some tips if the software doesn't help you.

Go to Control Panel - click on System - Click on Hardware - Click on Device Manager - click on IDE ATA/ATAPI Controller.
Then right click on Primary IDE Chanel - then click on Properties - Then Advance Settings - For the Device 0 in Transfer Mode select DMA if available. Then Click OK.
You can also select DMA for Device 1 too

try this. go to BIOS, from your main page choice sata1 and press enter then press DMA MODE and chanege to UDMA5 press enter F10 save and exit

Method 1: Change the transfer mode for your CD drive in IDE Channel Properties
1. Click Start, right-click My Computer, and then click Manage.
2. Under Computer Management (Local), click Device Manager.
3. On the right side, expand IDE ATA/ATAPI controllers.
4. Right-click the channel where your CD drive is connected, and then click Properties. Typically, this channel is Secondary IDE Channel.
5. On the Advanced Settings tab, in the Transfer Mode box for the device that represents your CD drive, click PIO Only. Typically, this device is Device 0. Then, click OK.

If the issue is not resolved after you change the transfer mode for the secondary IDE channel device 0, your CD drive may not be located there. Use the same procedure to change the transfer mode back to DMA if available. Then, repeat these steps to change the transfer mode for IDE devices in the following order until the issue is resolved:
• Primary IDE channel, device 1
• Secondary IDE channel, device 1
Note Primary IDE channel, device 0 is connected to your boot disk. This is the hard disk that typically contains your operating system.

OR

Make sure that all cables are connected correctly
If you have another cable, try to use it. For USB devices, try to use another USB port. If it is internal dirve is there then Reseat it that means remove it and reinstal that
Then Set the BIOS as Default for that restart the system and before windows screen it gives the instructions how to boot in setup once you are in setup, on the bottom it says press F9 or F10 to set as default; different BIOS have different options so do the as the on screen instructons says.

OR

Try to access the media or device on another computer; try it on your friend or family computer
if it is not working contact your H/W Vendor

You have to tell the vcr which input to record on. Instead of a channel try "Line 1" or "input 1" or "Video 1". you can get there by going to channel 01 and pressing channel down a few times. match whats written above the input jacks with what's on the screen.

Check the status of the device in Device Manager to make sure that the device driver is working correctly. (If you need help doing that please ask.)

Audio Dubbing on DV: Here's how you do this: Play your tape on the TRV-9 and feed the signal into the TRV-900, using the Firewire connector. Set the TRV-900's audio option to record in the 12-bit mode. When this is done, you will have the video re-recorded on the TRV-900 and the audio laid down on the primary 12-bit audio channel. Then, you can run the tape back through for a 2nd pass in the TRV-900, with the recorder set to the audio-dubbing mode. The audio you put into the TRV-900 this time, will be recorded on the secondary 12-bit channel. You can select either 12-bit channel when you play the edited tape back or you can mix both stereo channels into the output. Once you record on the 16-bit channel, you can't dub audio back onto that recording, without erasing the original channel, as the recording space for both 12-bit channels is occupied. You can't selectively re-record just audio onto the 16-bit channel either, without the video being re-recorded along with it. Both video and audio are sent over the same Firewire connector, so you can't input them from mixed sources, as you can with analog recordings. Only the secondary 12-bit audio channel can be used in the audio-dubbing mode. You can't dub onto the 16-bit channel or onto the primary 12-bit channel. The primary 12-bit channel can be used only when you're recording video along with it.
