Transformer MIP260T-T102 (RCA L26HD31) Help

[rb0746]

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..

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.
