Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

red is normally power in and black is normally earth wire. Get a 12 volt dc transformer that plugs into the power outlet and get the plug jack socket from a electronic shop and solder the wires correctly (red to centre pole ) and it should work . You will need a high wattage transformer for this.

Spares for magna spot welder


Ebay is about it.

If you have the hand held unit for auto body, they do not service the transformer as a discrete part from what I have seen. Using anyone elses transformer or adapting something ftom a microwave is done at your own risk and should only be attempted if you understand characteristics of transformer design.

It is difficult to get hold of a service manual in the first place and then to find the spares if there is a failure that you have identified. Considering both factors and specially if the player is under warranty, then it is better to send the unit over for claims. Also it will be better if you can just open and check for the power to the display section and the power supply.
Other wise get an estimate to decide as spending on manuals and spares must be considered with teh possibility that sometimes you may need a repairing JIG to connect when the unit is taken apart.

I bought SH-GE90 DSP And I pluged into 240V source while the indicator was on 110v and now its not working will replaceing the transformer will help or it just simply gone.


It is not possible for us to be able to determine the extent of the damage. It is possible that only the fuse has been damaged. It is also possible that the rectifiers have been dmaged. The bottom line here is that there needs to be some examination of the unit and some testing of the internal components. The best case will use parts in the $5 range. Worst case you are looking at $50 or more in parts. If the cost is not too high, take this to a servicer and ask for a detailed repair estimate.

Replaced both the display board and the central appliance board but cannot get anything to work on the display


If you have done that and still No Go, then you most probably have a problem, in something common to both, and that is the Power Supply.
You need to get a Service Manual, for your exact make & model. I have included a "Generic" Range service and repair manual, which, will still be relevant to troubleshoot. but a manual exactly for your make and model, will have the exact, details, such as a circuit diagram, and such. However in saying that, it will be possible to fix, this, with the Generic manual, as they are all basically the same. So work through the troubleshooting procedures, and pay special attention, to the Power Supply, and any other "Common" to bath, faulty boards.

Above, is a generic range service manual, above that, DIY repair how to's, above that are other troubleshooting and repair websites, to help. BUT you really need to get one for your exact make and model, even if you must pay for it.

Failed power transformer


With out make and model, I can not supply parts information. Please update this with that info. Also, depending upon the age of the unit, parts may not be available. Are you sure that the problem is the transformer? This part is rare to fail.
