    Sharp LC-37B20E need to change channel plan

    This TV is a UK model brought into Australia a few years ago. Repaired it by changing out the inverter and now realise it doesn't tune to our Australian DTV frequencies. Owner now tells me he uses a set-top box to drive the TV.

    I'm investigating the possibility of loading in compatible firmware for Australian frequencies. Looking into the matter last night, I don't recognise a direct one-for-one between the UK model and any of the Australian models sold by Sharp.

    I've downloaded the firmware for the three 37" TVs sold by Sharp into Australia, of which only two are 1080 TVs, so I'm down to two possibilities. I also have downloaded the firmware for the UK model.

    My concern is if I start mucking around with incompatible firmware I might not be able to get it back to the original firmware.

    I've thrown the question back to Sharp Australia Technical Support but doubt I'll get any reasonable response as the TV was not sold here in Australia.

    Anyone had this challenge with other brands of TV and how did your experience go?

    Also, does anyoner have a ready-reckoner of DTV channel frequencies used in Europe? I went looking on the net and could easily find a table for the UK, let alone for any of the other countries.

    This TV can be set for any European country. I was hoping I must stumble across one which was similar to what we use here. I only need five freqencies: CH29=536.5MHz, CH30=543.5MHz, CH31=550.5MHz, CH32=557.5MHz, CH33=564.5MHz

      Isn't there like Country codes in the service menu?

        Yes there are Country Codes, but this set only has options for Europe. Obviously it was only intended for sale in that market. I suspect models sold in our region have options for Oceania or Asia.

            More reading there, some say you need a set top box: https://www.pomsinoz.com/topic/14808...-in-australia/

              Thanks NOMORESONYS for your research. I just tried the Germany option, but it doesn't resolve the DTV issue. The references in those posts to compatibility with European countries were with regards analogue TV, which was switched off here some years ago.

              Customer will continue to watch via a set top box and I'm sure will have just as enjoyable viewing experience.

                Forgot to look at the dates. Pal is Pal, Uk. and AU. are both Pal, seems like it should work, might have to do a factory reset and initialization, curious to know why it won't work? Quite a head scratcher.

                  There are different versions of PAL ie PAL-M and PAL-I etc. But these are the old analog broadcasting standards, In the U.K. it is now DTT (digital terrestrial television ) using DVB-T or DVB-T2 (HD)
                  Australia also uses DVB-T but the modulation might be different (QPSK,16QAM,64QAM)

                  In N.America the standard has changed from NTSC to ATSC for digital over the air broadcast, They can use the same VHF channel (except for channels 2-7) but its not brodcasting an analog video signal but a digital signal.

                      So Australia is DTV then, so no way around a decoder/set top, xbox etc?

                          Nope seen it, just wondering why it needs the set top, according to wiki both countries do DVB-T2: https://en.wikipedia.org/wiki/DVB-T#...VB-T_or_DVB-T2

                            Ok, so it may be a modulation issue, any fix for that, besides the boxes? Not moving there just curious.

                              It is not an issue with DTV modulation compatibility (we are the same here in Australia as the UK and most of the rest of the world). The issue is our channel plan is unique to Australia. The allocated frequencies here in OZ can't be detected when the tuner does a scan as it is looking at particular frequencies depending upon the country code set up of the TV. (With this set, you do a factory reset and then allocate the country in which it will be used. But as prevoiusly mentioned, the only option are European countries.)

                              And that is why the current owner uses a set-top box and looks like that is the only solution going forward. Without a firmware change that includes Australia there appears to be no other option, but was worthwhile throwing it out there to see whether anyone had any other thoughts on the matter.

                                mad thought but it maybe could be done .that is fitting set top box into tv somehow .

                                    I thought they should all be the same modulation but was'nt sure so I thought I would suggest it.

                                      Hi friends

                                      I have reverse engineered this tester, schematic is attached and is complete except for capacitor values. These testers annoyingly have no model number but they are the ones you find on the first page of just about any website if you type in "18650 4-channel tester". There is also a 2-channel variant and a newer 8-channel variant. They are very cheap (about £15) and can measure voltage, current, internal resistance and capacity. They have a multicolour display for all these statistics. They also have terminal blocks so that if you want to use a breakout board...

                                      Hi guys I have a VLP1500 amplifier here - one channels works fine and the other channel distorts even at low volume settings

                                      Protection and Clip LED are off

                                      There is something wrong with the BIAS voltages around T16 and T18 (in particular) on the bad channel

                                      I tested all diodes and transistors in this area in circuit with diode mode - both channels seem identical. Same in resistance mode across all the resistors here.

                                      The output DC voltages on pin1 and pin8 of the 5532D dual op amp at the input of each amplifier module are the same, and the audio...

                                      He also has an LG TV, so three screens in the bar

                                      I need a help with my Marantz pm6005. It started to have weaker the right channel a few months ago, than it got back to normal and now it has lost sound completely on the right channel. At the final stage it was loosing the channel for a while and than it returned. After it has disappeared completely I could forced it back by unplugging the source form CD (which I normally use) to phone and back. It would then work for a few minutes and died again. Now it is possible power up and all function works normally (apart the right channel ) on all inputs, except the phone both channel...
