The module was set to give out 110V when I used it in a CRT TV. I used that only for such needs. But I had to use this module as I was not having a spare one at the time the technician came in. Many thanks for your observations and comments! Looks like I had got crowded with a lot of pending work when I prepared the article and missed even essential details. Anyhow, it shows that my article is being read in full, which is a solace! (LOL)

The Switching IC in the primary was the culprit. It had failed and no replacement was available. So a three wire SMPS module was used, ignoring the green wire. I have explained abou the use of this type of module in many of my previous articles and did not therefore repeat it. Many thanks!

Waiting for more explanation on these statements, 'You will find 110V marked......" Just has Albert.B observed.

Your expert fixes often go too quick and escape a clear explaining. Especially in these cases where again such a universal power module was used to replace a not working original pwm controller circuit. By leaving out the new changed circuit connections it doesn't help most readers, who never used such a module, in understanding how the modification was done. And a remark like "You will find 110V marked on the module, as this was adjusted like that, which I changed to minimum" then only adds to the confusion.

This is totally over my head Maestro.
Please kindly explain what you believe the fault was and what the name of this ingenious work around is called.
