The elusive Indextron

[jhalphen]

Hi to all,

This week (Oct 11th 2021) a Sony XKV-55 Indextron "car TV" sold on E-Bay.
It was located in Australia.
TV was +/- recapped, produced a distorted white raster, no video.

Hoping that someone from this forum acquired it, will fix it and post Indextron photos sometime in the future.

3x photos from the E-Bay auction.

Hi to all,
Hi HelloVoltage,

Well Thanks! for informing the forum & Congratulations! on acquiring a rare Indextron family item.
What's the condition ?
Planning on getting it to work?

I've never seen a XAV-55N, does it look like the XKV-55 standalone TV or is it a display unit designed to be used with a car system (diversity TV receiver, FM radio, CD player & multi-channel audio amp)? (see photo)

Schematics are going to be hard to find, never seen a service manual this side of Japan.

Condition externally is very good. Actually , since it was pulled from a mid 90s nissan, I would consider it excellent. No reaction wear in the buttons.

Internals are yet to be determined. I am currently repairing a kv-4sv1 that was at the point of transistors being corroded off.The xav is next in line. I have a few of the indextrons

the xav-55n Is designed to be used with the diversity unit, which I don't have. I figured it is not necessary for my use. Can purchase one later if needed.


Schematics are helpful but I expect the xav to function fine when powered. Schematics for the watch cubes are not as helpful as they likely once were. The corrosion removes logical troublesooting. Just slowly clean and replace. The plastic structural supports always snap...

Hi to all,
Hi HelloVoltage,

Thanks! for the HD photo of your XKV-55N.
Hope you will get it working in 2022.

With luck, this model avoided the horrid leaky purple Cap issue which plagued the Cube Indextrons & corroded fine PCB tracks. Different model, different time.
Never seen a Service Manual, but probably some common highly specialized ICs which Sony developped for Indextron signal processing.

Best Regards & Best Wishes for the New Year,

waiting for parts shipment, decided to assess the xav. Powers on, no control response. Definitely a couple of obivious cap corrosion point, but nothing like the watchcube.
not going further until i increase cap-acity.

Hi to all,
Hi HelloVoltage,

Nice photo of the XKV-55N insides.
Also test & beware of small Tantalum capacitors, they tend to fail shorted.
Usually used as decoupling Caps on DC power rails.
I see a small light-blue one with a black dot at the forefront of the top PCB.
Probably more elsewhere.
