Fixed a 26" Gateway LCD TV/monitor (bad solder joint in the SMPS). But exposing the component side of the power supply requires pulling off 2 heat sinks that are glued to the tops of the 2 transformers. Some of the glue pulled off of the top of one transformer (about 3/16 inch, or 5mm thick) and a copper strap that winds around the laminates came loose. Is this really a heat conductor? Seems to be not possible, but then I'm no glue chemist. Should the missing glue be replaced? What should I use? Is it important to relocate the end of the copper strap? Regarding the other transformer (the glue is intact), should anything be placed between the glue and the heat sink (ie, heat sink compound), or just clamp down the heat sink? The "glue" is white and seems to be the same stuff used to attach some of the components to the PCB. It is a bit flexible but not very; it crumbles when scraped off or when a sliver of it is bent. Not epoxy, no way. Here's the top of the transformer:'s what's left of the material, stuck to the heat sink:Sparky

how to download from that site ?I just get auto-redirected off site--Diverse Devices, Southampton, Englandelectronic hints and repair briefs , schematics/manuals list on

PS transf. to heat sink glue?

I would say that those "tests" were flawed then, as were the results, and likely, the methods.
