Re: the tv keeps blowing fuses
Hi your problem is that a component(s) inside your TV has probably short circuited to Earth, this then causes a massive current to flow and this blows the fuse.
Due to the types of Component failure from this, this TV should go to a reputable repair shop. Get a firm "Quote" and an explanation of what needs to be done.

on the power board you will see a black flat ac converter with this on it + ~ ~ - on it check this with a meter its more than likely to have gone as its the first thing to go in a storm. the + and - can be the other way round ~ ~ is the mains volts in and + - is the volts out if the ~ ~ has no resistance it has blown and it will keep blowing the fuse check the + - and you should have a resistance from the rest of the power board.
You will need to remove the back of the TV. Don't worry, it's not that bad.
There are 4 screws across the top, one on each side, one right next to
where the power cord goes into the back of the case, and the two more
by all of the video connections **These are the most important to
remove because they attach the main board to the back of the case.
Once you have remove the screws then the entire back of the set will
slide off. If you look where the power cord attaches to the board you
will see a small fuse. This is a 6.3 Amp 125 volt fuse. You can replace
it with a 6.3 Amp 250 volt fuse from your local Radio Shack. A four
pack costs between $3 and $5.
Make sure that you check that it works before putting it all back
together. Check for any loose connection cables while you're back
there. I found a few when I did this.
if you have replaced the fuse already then you know how to open the back of the set . The problem is more than likely one of the diodes in the rectifer circuit . They will be the four large black components The bad one will have to be desoldered and a new one soldered in its place . It will take a small amount of technicial ability but can be done easily at home.
If you look on the board that the fuse sits on you will see printed it states 6amp 125 Volt / 3amp 250Volt. This means that you can use either one. I think that is why the fuse states E.6.3 125Volt... I think it means either 6 amp (125 Volt) or 3 amp (250 volt). I noticed on the back of a fuse package that I bought that it stated these were interchangable so I put two and two together.
