Sylvania 6632 LG blows fuse when plugged in

My Sylvania 6632 LG which is 13 months old (out of warranty) would not turn on. Upon investigating I found the line fuse (4amp) was blown. I replaced it but it blows immediately upon plugging in the TV to power.

Do I need a new power supply? If so, where do I buy and what's the price??

Re: Sylvania 6632 LG blows fuse when plugged in

I too had this problem. I read some posts on this site about how to repair it, and low behold, they worked! I took the back off of the TV, and the first thing I found was the fuse was blown. With my meter, I checked the first 1N5406 rectifier diode after the fuse, and found that it had shorted out. Then I had to learn to desolder the diode, which I learned about on Youtube. I bought a pair replacement diodes at Radioshack for $1.49 and four replacement 125 volt 4 amp fuses. The whole repair cost about $5.00 and a few hours about learning about electronics. The TV works great! Good times!

Sorry, these are cheap TVs built by Funai for Sylvania. It will need at least a power supply. None of my parts sources list it. You will have to go to an authorized servicer -

If a fuse should blow up, there should be a reason for it. If you replace the fuse without rectifying the problem and switch it ON, the newly replaced fuse too will blow up. Before replacing an other fuse, find out the reason and rectify it. There should be some shorted component/s at its main power supply board. Check and replace them. If you wish to get more details, check this link. It has schematic diagram of power supply section to many televisions. Pull up older posts by its left side bar. Problems to Sylvania too will be there.

Watching the TV and heard a "pop", it went dead. Opened up the back and found a blown 4A 125V fuse. Replaced fuse and plugged in TV. Fuse blew instantly when I plugged in the TV. Sylvania...

The power suply unit may be dead......if the fuse blows instantly it means that the main input is short.
possible parts damaged :the diodes from the mains, the power tranzistor and the ic from the primary part and other components around them.
First unplug the tv, unload the mains capacitor (using a light bulb) check all the diodes from the rectifing bridge, check for any shortened semiconductors or blow resistors.

Tv blowing fuses

More likely to be either shorted out bridge rectifier or MOSFET in the primary circuits of the power supply. You need to Ohm out those parts.

One month over warranty!

Save yourself some agony. Call Toshiba and see if they could give you a warranty concession being that it is just over the year warranty. The cause of the failure is either the Main Board or the LCD panel. If it is the Main board it would cost approx 450.00 to 500.00.
If it is the Panel it would cost more to fix it than what you paid to buy it in the first place.
Hope this helps

My 2 month old 37" LG HDTV won't turn on...

You might consider using Best Buy's "Geek Squad" just to make sure the set is not a dud.   I'm sure if it's near to the 30 days, they would be real schmucks not to replace it.   But, maybe it's just a setting somewhere in a menu.  Have a good look at the manual with a beer, and I'm sure you will find something useful.
Good luck.
