Vetta II 2.03 and 2.5 firmware download

Recommended Posts

DickFoster,

 

Thankyou for confirming the logical approach I am undertaking. All guess work on my end when there is no LCD activity. Battery first, then upgrade. My Fingers are crossed. :-)

My Vetta combo has a VDI Card. It has to be removed in order to remove the PCB that houses the CR2430. Remove cable connectors to the VDI and 6 Phillips head screws. Card comes out easy.

I prefer to place hardware back into its original location. It takes the guesswork out of where everything goes. They also do not wind up on the floor somewhere!

Almost there. To remove the PCB, remove 4 hex nuts AND 4 XLR screws. Unplug any ribbon cables attached to board and remove 3 Phillips head screws located atop. Unscrew connection securing green ground wire. Carefully remove PCB.

Siilicon type glue was used to support and stabilize battery. Remove rubbery silicon glue located between board and battery using a small screwdriver. Notice CR2430 battery appears to float atop board. This space allows soldering both top side and bottom side of board that is double sided. Yes, traces on BOTH sides!

I am going to try and remove the battery by cutting the connective tabs close to the battery and leaving them on the board. This will allow me to run leads from the tabs to a battery socket that I will install external and separate from the board. I rather apply heat to the tabs than the board and possibly have traces lift.

 

Cut the bottom tab first. I used a thin x-acto saw blade. To prevent damage to the board, slip a small piece of credit card material between the board and the bottom side of the negative tab. Place the saw blade between the top side of the tab and battery. While cutting, stabilize any battery movement with fingers.

Tried to cut the positive top tab with saw blade but the battery moved a lot and was difficult to hold securely. Opted to use variable speed drill and dremel cutting wheel. Do this with a slow speed for better control and to prevent the cutter from uncontrollably spinning off the surface. Try not to cut into the battery. Here's the result.

Since my wife is a great housekeeper, I took the board outside to removed the residue of cutting wheel dust and metallic tab filings by using short blasts from a can of compressed air.

Next step is to prepare a scrap piece of breadboard to house the battery holder and tin the tabs on the PCB and tin the wire leads. Install and mount the breadboard assembly. Use hot glue where needed. Reassemble the entire amp.

I am very happy with the installation of the sub Board housing the CR2430. Continuity test confirmed. I tried powering the amp up. The Display screens were still unlit and inactive and a cyclic clicking sound was heard from both speakers.  I then tried a "Flying Blind" firmware 1.01 SYSEX update, using MidioxSE, Midisport 2x2 anniversary and Windows XP SP3.  The send SYSEX command finished sending the firmware file after about 10 minutes.  MidioxSE displayed its progress and did not hang up.  Pressing the vetta SAVE button did not place the amp in play mode. I am open to any suggestions before I open the amp up and start probing.  Thanks!

After checking all the ribbon cables connection I suppose the next step it to check out the power supply. Again the best place to share this these days is the Vetta group on Facebook.
