How to tell if the white fuse is bad - Sony KDL32BX300 32 in. TV

So, you have power on both sides of the fuse, huh? How did you test that? Did you use one of those voltage detectors that light up when they get near a "hot" wire? If so, then I would tell you to make sure your white return line (neutral line) is NOT hot, because if it is, then you probably have a bad connection in your junction box for your white (neutral) line. But if all that's fine, then you EITHER have a bad control console, or a bad control board, and I would bet it's the control board.

I do not have a fuse layout diagram but can tell you where the actual fuse is. Below is a picture and where you see the integration box or J/B No. 1 is the fuse panel it is in and is the one marked "tail". BUT (and there's always a but) If you look in this same picture you will notice a tail lamp relay which also could be bad. Now to top that off there is a fuseable link for that relay as well. If you are able to see any wires going to the connection of that relay, the white wire should have constant power (key on or off). If you do not have constant power at the white wire or if the relay has numbers on it, it will be number 1. In any case if you don't have that power, then you most likely have a blown fuseable link and will have to trace that white wire back towards the battery to locate the link that is bad. I hope I was able to help out and hope your just dealing with a fuse issue and by the way it should be a 15 amp fuse.

The white body fuse is the ceramic body type fuse, the rating of the fuse should be printed on the circuit board next to the fuse.
It can have shorted out bridge rectifier, shorted MOSFET, etc. You can try standard glass body fuse just to find out if it just has bad fuse. You can get ceramic body fuse from www.mouser.com or try Radio Shack.

It sounds like the thermal fuse. Without knowing model number I cant tell you exactly. Depending on how you access it. Near the blower housing you will see a little white sliver fuse ot a round fuse with two wires running to it. The one next to it has 4 wires running to it. Disconnect power before opening the dryer... Take a meter and see if it has continuity. If not its bad. Anything further please feel free to reply.

Hello, My names Dave and I can tell you that you all most likely have a bad Z sustain or Y sustain board! The good news is that most of the time if either of these boards are bad you will find a blown fuss one them! I have worked on this same model of TV many times! You can lay the TV face down very gently and remove the back cover from the TV and test the fuses on the Z & Y sustain boards to confirm which one of the two are bad!

Z sustain board! P/N's: 6871QZH956A or 6871QZH056B Here is a link to the Z sustain with a picture of the board so you'll know what you're looking for http://www.shopjimmy.com/lg-6871qzh056b-zsus.htm

If you look at the Z sustain board you'll see that there are two white fuses on the board FS1 & FS2 are the location #'s. There is also a third fuse (FS3) it is a surface mount type fuse and can be easily over looked. Just locate the 8 pin main plug right next to the other two fuses and you can't miss it. It's smaller and it will have gold colored ends on it and it to is white with the location # FS3 next to it!! If any of these fuses are blown you will need to replace the board to complete the repair! You will need to test the fuses for continuity with a DMM (Digital Multimeter) Do to the fact that you will not be able to just look at the fuses and be able to tell if they are good or bad!

You'll also want to test the three fuses (FS1, FS2, FS3) on the Y sustain board P/N's: 6871QYH953A 6870QYH005B ! Here's a link to a picture of this board also. http://www.shopjimmy.com/catalog/product/view/id/179043/s/ysus-6871qyh953a/

Two of the fuses (FS2 & FS3) on the Y sustain are easy to find because they are normal white fast acting type fuses! The third fuse is also a surface mount type fuse and can be easily over looked. Just locate the 9 pin main plug right next to the other two fuses and you can't miss it. It's smaller and it will have gold colored ends on it and it to is white with the location # FS1 next to it!

If any of these fuses are blown you'll need to replace the board to complete the repair! You will need to test the fuses for continuity with a DMM (Digital Multimeter) Do to the fact that you will not be able to just look at the fuses and be able to tell if they are good or bad!

Check to see if the little tab , the door closes against , clicks . If so , then the thermal fuse , a small white part with 2 blue wires going to it , is bad . This piece is usually located on the back of the dryer , or , behing the lint filter housing . Without the model number , I cannot tell you where .

You have a bad thermal fuse ( a small 1/4" wide by 1" long white piece , with 2 wires going to it , or a 2" long white oval piece with 2 wires , going to it also ) . Unable to tell which you have , and location , without complete model number . After replacing , check your vent hose for kink , and make sure the vent has good air flow to the outside .

Yes there is a little white fuse behind the back panel take the 9 to 11 quater inch screws out and you will see a white fuse down below check continuity on it or connect the wires.

Note whirlpool parts surplus is not liable for any damage.

Try finding the gamma/brightness potentiometer and turning it ever so slightly, testing each time to see if you are adjusting it correctly. If I'm right, it will be on the same circuit board as the cable tuner. I'm not a p42 owner but my dad has a vizio of another kind with this problem.

You probably have a bad thermal fuse, small white two teminal fuse on the blower housing.
