Thermal fuse Please tell me where is the thermal fuse located. Also, do you really just connect one end of the fuse? How does this complete a circuit and fix the set?

50 Emerson LED LF501EM4F will not power on. No standby light.

Hi. Please check that the power cable is okay. Then, open tv and confirm that the fuse is okay. If fuse is okay then power board has an issue. It could be a capacitor,resistor,diode or ic. If fuse is blown, do not replace it before the tv is checked to prevent more damage. To know whether tv has a short circuit or power board has a fault, Get a 60 watt filament bulb and remove damaged fuse then solder some wires to the two bulb termini and solder the two ends at the two points on the fuse and power the tv. If the bulb come on and goes off then the power board is okay because this signifies that a circuit is complete. If the bulb goes on and does not go off then it means that there is an issue and the circuit is not complete. Under state 1 replace fuse and power your tv and it has to go on. Under state 2 please have a qualified technician check the power board.

In onida tv d2498 and fuse in power supply gone on connecting ac.Without main board installing please help

If it's not the main board that's causing the fuse to blow then you have a short circuit somewhere in the power supply. Check things like the electrolytic capacitors. The ones that look like little cans. They should all have flat tops. If any are bulging out at the top they will need replacing. Also check the bridge rectifier which is a black component usually standing up on the board with four legs. If there is no bridge rectifier there will be 4 rectifier diodes together. They are black cylindrical items with a sliver band on one end and a lead out of each end. They are usually located near to where the mains lead enters the power board. Other things to check are power transistors, they are usually 3 legged, (sometimes 2 legs if they are used as a diode) black items with their case fixed to a heat sink (aluminium block.)

Where is the thermal fuse in power supply LSEP1279

It could be located next to the power inlet (phase+neutral). It might look like a large ceramic capacitor, but is a thermal fuse. You can see a similar one in the SMPS circuit as well in some models. There are some which will short the circuit to blow the fuse and there are some that will open up, cutting the supply off.

Model 37M32ID/37 magnavox LCD. Replaced capacitor on power supply board location 2074 with 2200uF 35V. Fuse continues to blow. Replaced fuse with 250V F500mA. Is this the correct fuse? Original...

I think that is the wrong fuse but still it would pop if you have a line problem on the circuit that fuse is piping for a reason not the value but there are more issues on the circuit then what you repaired I would start digging and see if there are more popped caps! not in the power supply but else where like the hd push board or the decoder in better terms.

Thanks hope this helps if you cannot get it done take it in for a estimate as estimate will tell you the issue fixed or not and you can take that advice from that tech and repair your TV!!

Please do click the accept button if you like my advise.

May i suggest a service manual?

Looked and the thermal fuse is not broken

check again thermal fuse that you replace maybe wattage is not enough. there a lot of protection in that circuit.

Vizio P42HDTV10A picture faded and washed out

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.

Thermal fuse replacment

The thermal fuse is located under the lamp housing in my TV. It’s a dime sized device mounted to the bottom of the TV with two wires coming out of it. The newer model Sony uses an upgraded thermal fuse, part number 191002393, that looks like a tiny black square plastic at the end of the two black wires. It is mounted next to the lamp (right side). It is accessible from the front. A skinny long nose plier can be used to grab the wires to lift up the fuse out of its holder but there is not much room to work with. Then you will need to remove the two screws that holds the plastic piece where the fuse is mounted. (the two screws are accessbile from the back using a long cross tip screwdriver). Then you have to slide the plastic piece back and lift it up a little to be able to slide out the bad thermal fuse and slide the new one in. I found this process very frustrating. If you do not have a lot of patience, I advise to just simply trace the thermal wires of the bad fuse back at the connector then unsnap to remove. install the new one in and just wrap it around the wires of the old fuse so it's not dangling. Install all the covers and enjoy watching (again). Hope this helps.

VERY Easy to change!!! We took the back off and on the right side by the fan is where it connects, just like KimSm said.. My husband called the shop and they wanted to charge 100 to come and look at it, 100 to take it with him if needed, 50 a night storage fee, 600-700 to fix it... He went as far to tell my husband there was no way we could fix it ourselves, there was soldering involved,circuit boards involved.. All lies!!! I just happened to stumble across this website and I am glad I did.. Saved a bunch of money. Thanks Everyone!!! Harley_Diva

Sony model KDF55WF655 blinking light 6 red flashes,no picture,no sound....
I just replaced my thermal fuse for $4.80 plus shipping handling.Took me 30 minutes to fix and 30 minutes to get dust out of TV.Take off the back of the tv about 8 screws,then remove the fan housing on the right hand side about 4 screws.If you have the new fuse you will know which wire it is ..grey and white.I found it easy to get to the other end through the front panel of the tv only 2 screws ,remove front panel and then remove cover on projection bulb and you will see the other end of the fuse clipped on.Remember to unplug tv. TV is working excellent now .
Thanks to everyone on this website.I have pictures if anyone needs them to repair it.

If your set is going to cost you $495.00 to fix it then you might as well buy a new tv which will be cheaper.from my experience that tv will only cost about between $75.00 to $200.00 to fix.get an estimate from another tech have them take a look at it.before they repair.and let me tell you that it is not the whole power board needs to be replaced just the regulator and some other components.good luck.
