transforming equipment asdrubal.jpg [65.11kb] Greetings colleagues I have a team like the one described whose fault is that it does not even turn on the display, when checking I saw the fuse in the open transformer card, when changing it it still did not turn on, checking the transformer primary notice that it is open too, I wanted connect the additional pin that has in the primary and did not light, I removed the plastic lining a little looking for some thermal fuse but I did not get anything superficially, to top I do not get information on diagrams to try to see the voltages of the secondary of the transformer on the card And trying to adapt another transformer and the option to rewind the original transformer here in Venezuela are very few sites that do it and it is as expensive as the original transformer. If any colleague has the link of a service manual of this model or that may seem to guide me in adapting a transformer welcome all your suggestions.

well in the absence of the diagram we can only calculate the replacement transformer begins by saying what type of amplifier and power this component handles if it is a transistor, if it has a double source (25 + 25 and 40 + 40) the voltage reading in the capacitors It also tells us a lot you can compare the source with this one. http://archivos.diagramas.mx/audio/MSX-S505.pdf

in the final pin of the transformer (ac in) it can be noticed that it has a hot melt jumpealo with the following pin, it may still work ...

Thank you for responding but I did that test without results, do you have the complete diagram of the team?

According to the diagram, there is a fuse in the primary Review

I removed the blue plastic and found no thermal fuse in the primary, will you know what the output voltage values are for this transformer?

To all the colleagues who contributed I appreciate your comments, I got a transformer rewind service and after rewinding the problem was solved, just connect and the computer started normally.
