    Transformer MIP260T-T102 (RCA L26HD31) Help

    I have picked up this set recently and the set will operate for about 10 minutes with intermittent high pitch sounds then will shut down. I think I have isolated the problem it being a transformer MIP260T-T102 . If I cool this transformer when the whining begins the whining goes away. And if I don't the set shuts down !. where to get this transformer from is my problem now any help ?
    I will attach a picture it is the little transformer with the white label .

      I would like to point out that when cooling T102 you are cooling a lot of other things in that area... In particular U102 and CON1 and Q101 and D101.

      Using an infrared thermometer you can pin-point the hot-spot... And a pic of the other side of the board would help.

          point well taken . I used a small diameter rubber tube and did several test with the same result does this help ? And I also did a re solder on the obvious points

              getting rid of all the C(r)apXon KM would be the first thing i'd try..
              they usually dry out.. no bloating..

                  Well I have found the problem( bad cable connection ) seems the controller was messing signals up .

                      Does someone in the forum know where I can obtain a schematic drawing for the MEGMEET MIP260T power supply? I have one that needs repaired. It has some blown smd's and also some electrolitics.

                      Thanks in advance for any help.

                          I have located the schematic for the MIP260T power supply now all I have to do is the diagnostic work and replace capacitors C109 and C110 right off . Both are shorted. As for T102 you may want to try Thompson Consumer Electronics. They use that same supply in their L26HD31 LCD TV.

                                  Original Xbox 1.0 PSU: Foxlink FTPS-0002 Rev. B. — 12 V low, 5 V high — transformer?
                                  by ohren
                                  Hello!

                                  I'm looking at an original Xbox PSU: Foxlink ftps-0002 rev. B. The 12 V output is too low, and the 5 V output is too (?) high. Unfortunately I don't have an oscilloscope but only a DMM for diagnosis.

                                  Measured voltages with no load:

                                  After rectifier diodes
                                  12V: 6.17 V
                                  5V: 5.67 V

                                  Secondary transformer pins AC measurement (really don't know if this says anything)
                                  12V: 2-2.5 V
                                  5V: 1.04 V


                                  I also have another (working) Xbox psu from Delta. The same measures there, in order, being: 10.79,...

                                  Is it possible for transformer substitution?

                                  Hi all,
                                  Got this local made DC power supply (12/14V) given free as the transformer has melted. There is no marking or indication to identify what type or rating of transformer used.
                                  Fyi,. I had a busted autogate mainboard with transformer with marking 13-0-13 . Is this the 13v dc type transformer?
                                  My questions are
                                  1. How do i test to see if the transformer is in good working condition?
                                  2. Can this transformer (marking 13-0-13) be used to replace the melted transformer on the DC power supply?
                                  Hope you guys understand what i was asking. My intention is...

                                  3PHASE STEP-DOWN Transformer in Check

                                  Hello All,

                                  i would like to post an interesting topic regarding 3-phase stepdown transformer which we suspect to cause an overcurrent (138A) which resulted to power tripped off of the HV power supply (80KV output).


                                  Problem statement: Power tripped Off

                                  Initial Problem: Found 2 IGBT and 2 rectifier diodes shorted (burnt).

                                  Action Done:
                                  1) Replaced the faulty parts with good spare.
                                  2) Measured impedance of the 3phase input lines and found that L2 to L3 has 23.3ohm while other pairs are 51Kohm. This pins will...
