    Onei 26av400

    Hi where could i get a service manual for this set ? onei 26av400 (17pw26-4 v.1 vestel),very very similar to budget makes alba/bush.
    The symptoms are no screen or sound,blue light when plugged in,switch it on.you get blue flashing continues light and even after you have pulled the plug,carries on for a bout one minute.
    Thanks to all who replies

    What's the main board model e.g. 17MBnn-n where n is a number.

        OK, on this chassis, test SMPS diodes for shorts.

          So test the diodes on the vestel board,I did change the start up caps but no change,I have looked at these diodes what no description on these to get replacements ?

            If you find a bad one, then we can help you source a replacement. First you need to test them. Do you know how to test a diode? Do you have a multimeter?

              Re: Onei 26av400

              Yes have a multimeter,don't know much about using it tbh,take it you test these diodes when the set is on ?

                Test while it is off and unplugged.

                      Also what should these diodes be reading.

                        I already did so for the same power supply in one of your other posts. But here it is again. Just tell me what the readings are. Also, you NEED to make your pictures clearer -- I do not have this board in front of me!

                          Cheers Tom,the diodes that are screwed in they have three prongs ? Do you miss the middle one out when testing.

                            No, test all six pin combinations: 1-2, 2-1, 1-3, 3-1, 2-3, 3-2.

                                    This is a diode.

                                    It will look like lower symbol, may be combined onto 2000 ohm setting.

                                          Hello,

                                          I've been given an Alba CBB16 radio to look at. The issue was no sound from either speakers when switching to the radio. They'd just be some buzzing/static. I did some troubleshooting and found that if I mess with the switch in certain ways, the sound cuts in and out on the right channel speaker. It'll go from quiet with some static/buzzing to really loud and clear depending on how the switch is moved. This told me that the radio at least has an issue with this switch.

                                          The switch appears to be broken on the inside causing a poor connection. I tried cleaning it...

                                          Hi all.
                                          Im trying to access the sd card in my ALBA 10tablet directly from my pc, but when I connect using using usb its only showing the internal storage.
                                          I have a samsung tablet and it shows both internal and external storage when connected but no dice with the Alba.Is there some setting i'm overlooking.?
                                          My grandson has an amazon tablet and again the sdcard is not there when plugged in to pc.

                                          Thanks for any help.

                                          horizontal "smear" panel fault?vestel alba lcd 40781f
                                          by jimbofz
                                          Hi this early vestel with inverter and ccfl backlight came in with no backlight and it was the usual suspects on the inverter board ,4 fets ao4616 ,i ordered a kit and repaired inverter .
                                          i now have this smear approx 8 inch from bottom on left hand side
                                          its about half inch wide it stops approx 3/4 across .it doesnt change with pic content
                                          i have examined panel closely for any damage ,
                                          none of the tabs are running hot .
                                          would value your opinions if it is the panel.
                                          ive had many plasma and lcd tvs with horizontal lines,
                                          but they usually go right...
