Thermal fuse replacment

I'll try to make this short. I got a service manual. I removed the duct fan, chassis assembly and the optics unit block assembly. I'm having a hard time finding the thermal fuse. I think it’s on the "guide, lamp case". Is it the round disk with the 2 wires coming into it?
The part I order is 191002393. It has a plastic connection at one end and at the other end the two wires come together with a plastic tab/cap. There’s no round disk, just 2 wires. One white, one black, and then half way down the wire they are heavily shielded with black tube. Any help you could give me would be greatly appreciated

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.

SUSPECT THE THERMAL FUSE, SEEMS TO BE A COMMON PROBLEM. HAVE THE WEGA KDF-55XS955. JUST NOT SURE WHERE IT'S LOCATED


To reach the thermal fuse you will have to remove the optical block assembly. Remove the back of the tv, about 12 screws. Removed the large support plate, and the small support bar on the left. Remove the buttom screw on the large fan on the lower right. Remove the connections to the bass speaker and the fan connections. Slighty lift on the large board assembly on the left and it comes right out after the small support is removed. There are two hidden screws holding in the optical block. You will need a long phillips screwdriver to loosens these two screws. They will loosen, but not come out. This will allow you to remove the optical block enough to to get to the front section of the TV. You should see the bulb attached to the optical block. If you look close, where the bulb was resting, there is a plastic plate with two screws, and a wire running through it. That is the Thermal Fuse. Remove the two screws and you will be able to remove the Fuse. Install the new fuse and reassemble. I recommend you remove the cooling fan on mounted above the bulb and clean it. This fan gets very dirty. Good luck.

I'm replacing a fan and thermal unit


No, not necessarily the entire unit. Once you remove the chassis cover, the harddrive, optical drive & its fan, then you will see that the processor is covered with the heat sink or another term for it is thermal unit. You will not remove the entire motherboard of this laptop since the thermal unit is placed above the processor wherein the processor is placed at the center part of the motherboard. Another option is you can go to acer.com for manuals or you can call the acer tech support for more tech assistance

Sony KDF E60A10 60 in. My TV starts up but then the green light switches red and blinks 6 times. No picture or sound. What is the issue


6 blinks mean a thermal fuse problem. This model had a problem with the thermal fuse that does not close once it is opened. This is caused by a blockage of the fan that cools the optical block, usually from accumulated household dust. This causes the TV to overheat. The thermal fuse detects this and puts the TV into protect to prevent further damage to the TV. To fix, the fans need to be cleaned and the thermal fuse needs to be replaced. The parts are not very expensive (around 20 dollars for the fuse) but it does usually takes a while to fix because the unit needs to be taken apart to have access to the fuse and optical block fan. The GT board might have been damaged for the excessive heat but most likely a new thermal fuse will fix the issue and clean fans will prevent it from happening from the future.

Bad fan motor on DH504ELY5?


problem fixed with the fan motor not running.

heres how i did it for anyone who experiences the same problem

1.) open back of unit(6 screws and pop tabs)

2.) with back cover open youll have access to compressor and fan-locate the blower assembly and remove the nut on it i used a 3/8 wrench from dollartree and rotated the blower fan while turning-its plastic be careful and remember righty tighty lefty loosey)

3.) with fan assembly off youll see the motor with 2 phillips head screws-taking these screws out with a power screwdriver allows the bearing assembly closest to the fan assembly,shaft,armeture and motor assembly to come out leaving rear bearing assembly attached to chassis

4.) once the motor assembly is completely out gently rest it against the fan hole and cut the silver tape being careful to ONLY cut the silver tape and the first white tape strip.

5.) youll see 3 wires and some insulator sleeves covering them leave everything alone except the ORANGE wire this wire attaches to the thermal fuse than to the windings
CAREFULLY heat up your soldering iron and remove the orange to thermal fuse connection than carefully thermal fuse to windings its a bit of a pain but can be done with patience

6.) remove original thermal fuse noting EXACTLY where original is placed on windings-it will have a small tape strip on it. replace it with one of EXACT OR NEAR THERMAL RATINGS a good choice is radioshack 270-1322. this thermal fuse is ratyed 10 amps max. but remember thermal fuses go by degree of heat and not by amp rating unless the amperage is in excess to melt the thermal material inside-my original fuse was 2 amps and 130 degrees celcius new fuse was 129degrees but plus minus 2 degrees so its a good choice and costs under 2 dollars

7.) place a heatsink clip or needlenose pliers between thermal fuse and solder connections BEFORE YOU SOLDER IT IN PLACE this prevents your 700 degree f iron from melting the fuse(remember its thermal not amperage were talking about here)
solder orange to thermal fuse with plastic extension than flat end to winding wire exactly opposite of how removed

8.) tape fuse in ORIGINAL LOCATION AS OLD FUSE i used scotch tape,place the thermal white protector piece on orange to fuse wire and push everything back down in original places-there should be no contact with any other wires etc. it will cause a fire

9.) once fuse is in place push tape you cut earlier back on and put 2 or 3 small scotch tape pieces of good length to secure the innards, lube the rear bearing of motor using vasoline- a few dollups will do it do the same for front slide motor winding assembly holding it in place than replace armeture with front bearing attaches as they came out secure the 2 screws back in place, put fan blade assembly back on(its keyed) secure nut and reassemble back

if you did everything correctly it will work like new just remember this time CLEAN YOUR FILTER SCREEN REGULARILY lol its critical for proper fan cooling

that should do it:)

6 red light blinks-possible thermal fuse prob.


The thermal fuse is located under the optical block. However the optical block needs to be removed to replace it. So unless you are very familiar with the disassembly of this tv I suggest you have a Sony ASC to do the repair work for you. You don't want to take a chance of damaging the optical block.

55 in Sony KDF55WF655 Goes to standby and red light blinks 4 times


Check the thermal sensor fuse part# 1-910-023-93 or possibly one of the four fans. If the unit goes into Fan/Thermal Protect shutdown (4 blinks) it can be difficult to determine the cause since the unit turns off too quickly to troubleshoot. Solution: Ground the data line by inserting a jumper between pins 3 and 6 of CN44 on the H4 board. This overrides the protection circuits for troubleshooting. Do this right after turning the unit on and as soon as the lamp is seen lighting. Check pins 2, 5, 8, and 11 of CN6000 on the G2 board for less than 1VDC. Any voltage higher than that indicates a faulty fan. If all voltages are within specs, the H4 board must be replaced. If a fan is found defective, the optical block will need to be replaced if it is located inside the assembly. H4 Board Part Number: A1054674A Replace the following part based on which pin of CN6000 is out of specs: Pin 2: Fan 1 (part of optical block) Pin 5: Fan 2 178723211 Pin 8: Fan 3 178706511 Pin 11: Fan 4 178708111 Optical block Part Number: A1084662A
