Hi again


From your description of the problem it sounds like the power supply circuit may be at fault.

If you wish to look at it yourself i`ll help you along,

Then the next step would be to take the back cover off and we could take it from there.

I am a single female who knows nothing about any of this. How hard would that be and would it mean still calling a repairman or buying a part myself. And looking at it myself would tell me what>
Expert:  Jack replied 6 years ago.

Well... it does involve removing the back cover.

If you can do that then i could point out the faulty circuit and it would only be a matter of unplugging it and removing a few screws.

I can give you then some addresses where you can buy/order that circuit.


So if you are able to remove the back cover then it won`t be much trouble replacing that circuit.

will have to see if I can remove back cover tomorrow

What i will do is give you all the info`s on your power board and where to get it.

So that even if you have to take the set to a repair shop then it should a simple affair for them to replace it, 1 hour at the most.

Just check their hourly rates.

It would be a good idea to buy it yourself as you will save quite a bit on markup for the part and on labor as well.


So here are the info`s

First this is your part number; 313815864961

This number can be used to search for supplier as well.


At this time though it would seem that all the suppliers with a reasonable(-$100) price are out of stock.

So i found this one on ebay;


Also here is a picture of that board;
