    Soniq E40V16A. AU no menus or picture

    This set came with an infestation of small cockroaches as it had been sitting in a warehouse for many months. Took it right apart down to screen and cleaned it up as best I could after getting rid of the inhabitants. Before and after this the set turns on with either remote or set button the backlight comes on and then chimes play but nothing on screen. Backlight stays on as does the set - it closes down itself much later. Have cleaned and reset lvds and checked voltage to sub tcon at just over 12v and also 3.3v to what looks like Eeprom. There is a long board across bottom of set with two strap connections to screen - they look ok but I have no experience with this aspect. My guess is either Eeprom or screen and the stupid all on one main power inverter board ST6306PUM-TP5 will prob be hard to find info etc or any firmware. Small board is marked STLVDS.

    I'm thinking tcon or panel if the chimes are playing, suggests it's booting up. tried connecting an antenna to see if you can hear channels?

      I agree just wasn't sure if chimes were startup one or shutdown but as backlight stays on should be the former. The lvdss goes to a very small sub board then to the bonded long board - at least I can see it but will be difficult to work on. Tried a DVD and cycled source button but nothing. Tv came from 150km away so won't be tuned to our stations and no menu coming up.

        Went thru the routine of selecting source with remote with DVD on HDMI and got sound on 3rd attempt so now ruled out eeprom and will look closely at integrated tcon and connections.

          Cockroaches chewed through the cables. Getting anything on your data lines?

            Well the problem of age strikes again - mine that is!!
            When first getting sets to work on I do a quick check on each for start up signs etc, make brief notes on scrap of paper, then put to one side until I get time to work on them. Of course for this one I couldn't find my notes until today and I had recorded there that Soniq logo came up before chimes played. This would indicate screen circuitry ok ? No damage seen on connectors or straps but in my poking about have lost the logo. On YouTube there are a couple of videos regarding loss of picture due to a glitch with energy savings mode. One guy gets his set to turn on with a button sequence which I tried - no go. Another solves problem with firmware update but doesn't say where he got that from. Soniq here tell me there is no new firmware for this model. So I'm back to Eeprom after giving the connectors and straps due attention. What do I need to do though to check signal output as suggested above?

              You can check with scope on data lines and see if you get anything. I also found with voltmeter you get about a volt if lines are active

                Kind of interesting, so the logo splashes up momentarily then black screen? I got a 32 that would not urn on, reflashed the firmware and then it briefly flashes the logo, goes out but tv is on.

                There may be no updates but can they give you the original file to flash?

                  have you shined a bright light on a 45 degree angle in a dark room to see if it is the back light?

                    As is usual with many sets the logo comes on with a few sparkling stars or whatever then backlight then picture. I was getting first two but shorting Eeprom and poking about I lost the logo although backlights and sound are ok and on. The set responds to buttons and remote. Soniq here useless but did find a US site with a heap of Soniq firmware and even though not my exact model have downloaded a bin file and have other info re loading it so will probably give it a go - nothing to lose now. techresources.soniq.com
