Eu: SCART & Alba/Bush ctv4858

[rstlne]

My FatherNLaw has a Alba ctv4858 .. I think they are the same as bush
branded kit..
But the problem is with the scart connector.. When the units connected to
the scart input is on then the TV wants to pull the signal from it ALLWAYS..
So even if I switch away from AV1 back to say CH1, CH2, CH3, (so on so
forth) then the TV still try's to show whats on AV1, The audio does switch
away properly but not the video..

Does anyone know if this is a "common" problem or maybee how much something
like this might cost to get fixed..

Thanks

if you mean the tv jumps to the scart input when that device is
powered, open up the scart plug and cut the lead to pin 8 to disable
the switchover (most radical). Or use a lead with a scart one end (tv)
to two phono plugs (device) to avoid the switching altogether. cheapo
ones can be bought anywhere, from Adsa to poundland!

Normally, there is a button marked AV/ TV-VCR / []<- / etc on one of
the remotes to flip between the tv tuner and the scart input. on some
models you can use a menu option to disable it.

Hope this helps, post your results!

Hi, Thanks for the reply.
Yea.. I know what your describing (normal operation)

What happens is say that I turn on the DVD Player.. So now the TV Switches
to it (that's what I wanna see)
But then I use the TV Remote to change the AV back to the tuner.. so Ch1,
Ch2, Ch3 (ect).. then the TV still keeps the video feed from the DVD player
but then starts using the audio feed from the tuner..
So the problem is that ScartInput is allways showing even when tuner is
selected..

have you tried connecting via phono plugs only? I'm 99% sure this will
cure your fault.Scart leads can be a pain in the a%$e!

No phono plugs on the TV.. but I am guessing now that MAYBEE I just have 3
bad scart cables.. I brought them home and will be testing them today. all
3 seem to make the problem slightly different so I am guessing that It's
just cheap/bad cables..

the problem I have found frequently in cheap scart leads is that
unless you insert them slowly and *absolutely straight* into the
socket, the pins bend or push themselves back into the plug body.

I strongly recommend you try the following: get two adaptor plugs
which consist of a scart plug and 3 phono sockets (L,R audio and
Video), ie. THIS:

http://www.cybermarket.co.uk/ishop/923/shopscr520.html

plug one into the tv and theother into the dvd player (assuming it
doesn't have video Out phonos, if it does you only need one adaptor
for the tv end), and link both with phono leads. This way you avoid:
-switching signal
-in/out 2 way communication from the tv, which can cause exactly the
symptoms you describe. it sounds like the tv is outputting a signal
from the tuner thru the scart jack as well as accepting the input from
your dvd -possibly giving a feedback loop. You on the other hand, only
need to use the tv scart jack as an input. NB when using a dvd player
in the setup described above, set output to composite video.

I am very sure this will solve the problem once and for all. post your
findings here!

I think that the TV is just broke..
I tested the cables here on my DVD player and TV (same model & make as his)
and they all worked fine in RGB, Svid, Composit..

His TV only seems to accept the signal if it's RGB or SVid and the RGB one
flickers sometimes.. the Composit one is either black OR it lacks the
color..

I am wondering if maybee I could modify the cable on the inside so if it
see's a voltage on pin 8 then it turns the scar tconnector on, and if it
see's no voltage then it'll cut off ..

I could break down and take the TV into a shop to have it look'd at but it's
just a scart connection and I really hate to spend money on it.

Either broken or a bad design. I have seen this also, even on one
input of a philips set I owned.

Have you looked at the menu on the TV? if it has a 'decoder 'option
switched on, then you will have this problem.

If you tried connecting the unit with the phono-scart adaptor, and the
problem persisted, then doing that will make absolutely no difference.
The set is mixing the signal internally by the look of it.

Alba is a supermarket special, let's face it it isn't worth spending
money on.Get a decent brand name set like a panasonic or Philips
(which has more than one input!). Second hand if neccesary.

good luck,
Ben

I got it figgured out (gawd)
The TV can ONLY work with Composite..
the DVD player Seem'd to output C+Svid or C+RGB (I take it this means
composite and Svid or Rgb)
I took my DVD player down, set it to Composite Output and now all is well,
Set up his digibox the same way..
Shame really that a 3 year old TV isnt as good as a 6+ year old sony
