Powers on and all appears to be working, however the remote control is missing so there may be functions that I am unable to test are working.

Unable to find a user manual online.

The problem is AV in does not work not even getting sound.
AV OUT has been tested working so the 3.5mm 4 pin jack plug cable is wired correctly (I would assume the same cable would do AV in and out).
The video source (a Bush PDVD-163C Twin 7" portable dvd player, also came with no remote) is working so can confirm the AV source works fine.

There is no AV switching button on the unit to toggle between AV IN and OUT so would assume it would auto detect between AV in and out (no av switching button on the unit and the setup menu I can access has no option either).

Main board 0320-D3123-00
The main components are:
EN29LV160AB-70TCP - 16 megabit flash memory
EM638165TS-6G - CMOS synchronous DRAM
MT1389QE - DVD player system on a chip (SOC)
MSV358G - dual op amplifier

Board and components look ok with no obvious signs of damage i.e burnt components, corrosion, dry joints etc... though I am no expert.
Only thing I do notice is a possible spillage on the board that has dried out and has discoloured a section on the reverse of the pcb along the input side but it is possible this is just heat / age related. An expert eye might be able to confirm either way with a photo to illustrate.

I have attempted to program various universal remotes to try and change the av source to 'A/V IN' but no luck, only get limited control via remote, i.e 5 will bring up DVD title detais, vol dwn will power on/off the device so not altogether successful.

So before DMM'ing any components could someone please advise.

Its not uncommon that AV in canot be activated with out the remote control. I have a Sanyo tv that does the same.

Ok so have put it all back together as I am sure it all looks ok.
Shall continue with several universal remotes to try and find one that will operate the player, quite sure if a code for Bush dont work another make will at least give me some kind of functional button presses.

Is there a way of getting it to stay on AV-In, hidden menu??? I want this to be a second screen that will 90% of the time be taking an input rather than using the DVD player. The AV-out is probably set as default.

Ok so have minimal operation via a universal remote, av in can be selected and confirmed as working so the player can be used as a slave monitor.

Now just need to try and set av in as default i.e powers up as av in.
Anyone???

I'm a little late to the party, but I'm trying to do much the same. Have you made any more progress with setting it for input? Is there a particular model of remote control you could recommend? Thanks!

I think I also have the remote (never out of the wrapper)
