Old Receiver Question |
|
|
I fixed it - it turned out to be a row of 10 solder connections tha
were all broken, and were wiggling around whenever the board wa
flexed. Resoldering them did the trick, now the display's working lik
new.

It's solder connections along the display tube.

I have an old Pioneer receiver (VSX-9500S, I believe) on which the
display only half works. The left side of the display, as far righ
as
"VIDE" when you have video selected, works, but everything right o
that
is completely dead.--

Some displays use a "presure" contact to the PCB. age and dirt may be
your problem. If the display unclips, a "PinkPearl" eraser may cure
the dirty contacts.
A cracked trace is possible on a Bank select pin.-
I had a VCR that worked like that. Turned out to be a bad
solder joint. You might also have a bad feed-through between
layers in the circuit board, a bad flex-cable, or a bad solder
joint where the flex cable connects to the circuit card.

Great that you fixed it. I am really suprised that ther were 10 bad. |
Was the original solder flow poor or does the display (heat?)flex the
PTH to cause the crack?

I've seen virtually the entire row of solder connections become bad over
time on these FL tubes. Age, heat, mechanical tension from the mounting and
I suppose flexing from nearby buttons pushed. Not just this model, either -
it's a fairly common problem with surround receivers and the like.
