    Bushle-46gl12e

    Hi guys just been given one of these 46in full hd sets it uses a megmeet MP4618 psu and a T.SIS231.81 T460H1 P09 L02 VER C1 main the problem you can get it out of standby ok the led flashes blue about 20 times the lcd screen is lit a dullish blue which stays on about 12 seconds all the edge lit leds seem to be lighting looking through the back of the tv metal chassis holes/ no on screen menu volume control source etc seem to do nothing would you guys say faulty eeprom? any tests i can carry out? cheers guys.


    sorry cant spell or edit the title maybe a mod can its a bush le-46gl12e

      Will do tomorrow a little dark here to take good pictures a visual inspection all looks ok i could pull all caps and test esr i guess but i see chs sells a eeprom maybe a common issue i will link pictures of the boards that are the same as mine so you can have a quick look but will upload mine tommorow. ive also noticed whilst the blue standby led is flashing you cant turn the set off on the side switch you have to unplug it.

        hi guys anyone have a schematic for the megmeet MP4618 psu as if possile i would like to jump the psu to check the voltages are stable this is a good clear picture of the psu as you can see it does not have the voltages printed on it

          Well... not thaaaat fast... You have STBY voltage. So first check if the main board returns PSon to the power supply. If that main board does not return PSon voltage to the power supply, the TV simply does not turn on.
          You may have a bad main board, let it be an Eeprom problem or the main IC.

            i would say eeprom, it wont be the first time i have had the same problems with these sets, technika, jmb, bush, to name a few, but nine times out of ten you cant get the IC for them and have to get another main board,

              cheers guys i think i will risk ordering a eeprom from chs or ohms supplies they both carry them for this tv so may be a common problem not many main boards for sale with all matching numbers i have searced ebay etc.

                the trouble i have i cant find a psu schematic to find out which is the pson wire etc its like the sets trying to boot for 12 seconds then seems to get stuck and re boots.

                  The labels for the pins are on the bottom side of the board.

                    Thanks budm thats one place i did not look as yet, regarding jumping the psu which pins do i use a 1k resistor across many thanks.

                      Again, first measure the voltages on those pins, since you have the pin out now and post them here.

                          thanks budm the voltages have just been tested with set in stanby and whilst its trying to boot for 12 seconds with just a dull blue screen no side buttons etc
                          no on screen menu etc
                          please see budms picture for bottom view of board with pinouts i cant add to this post sorry.

                          So guys whats your thoughts? is it worth trying a eeprom as voltages look ok? as no mains available cheers guys.

                                Other than that, it's worth a trying an eeprom.

                                  The voltage between the + and - is 93 volts on both cn05 and cn06 i will try to unsolder the eeprom later as still learning and very small traces (no hot air station) if i can remove ok i will order one

                                      Any news as I have just been given the same model TV with the same issues as yours?
                                      If its the eeprom then it sounds like an easy fix.
                                      I look forward to hearing from you.

                                        Hi sorry only just got around to having a go at the repair yes the eeprom has fixed the issue the set seems fine i will run it later for a few days to confirm its ok.I ordered the eeprom from ohm supplies about £23.00 a word of warning the tracks/pads lift very easy i did lift and break one but managed to solder a small copper wire onto the track and then fitted the eeprom.
