AV7 for sale - faulty but functional

[markspace]

I'm selling a faulty Panasonic AV7!

what an exciting proposition I hear you cry!

well, maybe not, as it has a chroma fault on the B bus - very green when you switch it on, then settles down, but not very reliably..

but, it works, and i imagine it will go cheap, so if anyone wants a spare mixer for dodgy parties, or mainly uses 1 source (A bus is fine) but needs a mixer for fx and fades-away to reload patches etc etc, or even spares/repairs then you may as well bid and one day i'll be able to afford a V4.

all abuse for taking the piss humbly accepted (but not from sleepytom who can piss off cos he lunched out advertising it so i have now)

as used by Headspace, Coldcut and the VJamm Allstars (wow, hold me back)

oh yes, boxed with manual, and PAL.

Invalid item??

[sleepytom]

haha - i might of lunched it out but at least i know how to post a working link / put something on ebay so that people can actually buy it!

anyone who's seriously intrested in this should contact me or mark directly i guess - its not too bad a mixer and the green issue is somewhat intermittent and could probably be fixed by someone.

Tom, I'm interested.
Next year I will have loads of time to spend playing with electronics.

hi there
. i have an ave7 with almost the same issue (this green thing on channel A) does anyone have an idea if its possible to fix that by myself (im a total noob in electronics) and i tried to get it fixed in a shop but they will keep it for a month or so, and thats not good! if anyone has an idea or a circuit board map or something, pleeeeeeeeeeeeease tell me. im desperate :(

[alangeering]

Do you guys have any stills you could give me from the video output? Would make it easier to diagnose what's going on.

It should be fixable, but maybe not elegantly, it all depends how far up the problem is.

If the problem is evident in the RGB (pre-PAL encoding) stage then there is little that can be done.
If everything is fine up to PAL encoding I can probably build a PAL encoder and bypass the faulty one... but this is not garuenteed.

Fuussmuuss, watch out or this will become a "hardware" thread, maybe if you want more help on this issue you should think about writing a full explanation of the problem in a post on the hardware section. Alan

my what a lot of time people spend reading this shite!

the ebay item is up at the url linked in my posting (just checked - maye you were quicker reading my post than ebay were in getting the listing online) - the auction starts monday as i said, as otherwise i'd be away when it finished..

fuussmuuss and alan - quite happy to compare notes/ swap pics etc if you fancy, but off-list i suggest until we have something usesful to contribute to the forum. i'll grab some output stills for the sake of interest.

maye you can comine my good a bus chroma chip and your good b bus one and make 1 good mixer with a spare box and set of knos!

this particular one though can be someone else's problem - i want to sell it as it's sat on the shelf for a year now.

Seems to be a common problem with the AVE7s... I just bought one off ebay and they said 'good working order' .. and it arrives and its green *grumbles*

Aanyway, rumour has it that its dodgy capacitors causing the problems... im gonna run out and get me a multimeter today, after i call my bank and get them to reverse the payment made to the people who sold it to me.... <*evil laugh*>

[alangeering]

it's worth buying a multimeter for your tool box...

...but I suggest you get friendly with a student or engineer who has access to an electronics workshop. It's so much cheaper than buying an 20MHz+ oscillascope, signal generators, frequency counters, etc.

These are the really useful tools for analysing a circuit. A multimeter can only tell you what's going on at one point in time. For DC it will be OK. They can't usually check inductance or capacitance.
