LG 52sx4d blows the 5a fuse on the small power board

When I turn the tv on, the 5 amp fuse (F800) on board (6871vpma88j) blows. Would a replacement this board fix the problem? The soldering job on the underside of the board doesn't look like very solid, but it's cheap enough I might just give it a shot a get a replacement board.

What I would like to know is if this board is causing the the fuse to blow or if another board is causing this board to blow it's fuse? There would be no use in replacing this board if it's not the problem. It just doesn't seem like there are enough or even the right components on this board to cause it to blow the fuse. But then again I don't know what this boards purpose is. I'll look into that, but if anyone has dealt with this issue before please let me know.

So I hooked the tv up, but disconnected the 3-wire connector on the small power board going to the large power board and the fuse didn't blow until I connected that connector. I assume the problem lies on the large power board.

Will not power up, something popped yesterday, and it lost power and will not come on

The fuse might have blown. Could be various reasons. Unplug the TV. Place the TV down on it screen (on a SOFT FLAT, UN OBTRUSIVE surface). Remove the back panel screws and the panel. There will be a fuse, it is likely blown. Replace it with a fuse of the EXACT SAME amperage (it will be stamped on the fuse [example 5A is a 5 amp fuse]). Replace the back panel and carefully tighten all the screws. Replace your TV on it's stand. Plug it in, and turn it on with the remote. If it works, great. If the fuse blows again, you have a more serious problem. Do not attempt to fix it yourself, it could create a fire hazard. Seek a repair shop.

Panasonic ct-32sl13g blowing fuse by power supply

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.

Good luck!

Lg 52sx4d problem

If the red light scrolls through, you need to replace the bulb. I replaced the my own bulb, and when I tried to turn on the tv the light kept scrolling. What was wrong? I DIDNT FULLY REASSEMBLE THE TV AFTER REPLACING THE BULB.

Make sure that all the screws are put back in and it will probably work if you have replaced the bulb.

Fuse blown

the fuse will always blow if there is a shorted component. the horizontal output transistor may be the most likely culprit, if you are not a technician, have it service by a qualified one.
