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.

My hitachi 50'' lcd tv shuts off and turns on automatically after a few seconds


Problem could be the thermal fuse cutoff on top of the lamp assembly. Has two wires going to it. A good test is to remove one wire and connect an alligator jumper to the two wires by passing the thermal fuse cutoff and see if it will stay on. Clean out any dust in the chassis as it can cause overheating. Do not leave the set hooked up this way permanently! Just to test!

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.

Sony Wega KDFE55A20 screen and sound going out, red blinking lights, but comes back on...then repeats. Replaced the bulb about 8 months ago and seemed to solve the problem. But it is occuring way too often...


p# 19100239 6 blinks indicates fuse. Do not plug set into switched outlet. besure set is allowed to cool down before ac power is ever removed. Thermal fuse is on the optical block under the lamp housing. do goole search for part availability and source.

6 blinks of the red power light


The 6 red blinks means that the thermal fuse is blown, sony part number 191002393, which can be bought off of Sony.com for about $5. You will have to remove the back cover, remove the OU bracket (It is silver with 3 ground wires connected to it), remove the fan bracket with fan and then the duct fan bracket (Plastic fan duct housing). Looking between where the fan was and the lamp on the front of the TV, there is a small silver metal disk with 2 wires connected to it, which is the thermal fuse. Using an Ohm meter, you can test it. If it reads open, it is bad. Of course, you must unplug the TV first and use caution. It is a very easy fix for someone who is handy. (Approx 10 minutes)

Were is the thermal fuse on a sony KDF E55A20


The CORRECT way to replace the thermal fuse is to pull the optical block out so you can get to the thermal fuse mounting plate. I would NOT suggest just letting it "float out in the open cool air" as some have suggested as this is a safety part and not installing properly could be a safety hazard

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.

Red Light Flashing 6 times


A 6 blink usually indicates a bad thermal fuse caused by the lamp temperature getting too hot. I strongly suggest replacing the sirrocco fan that mounts on top of the optical block too. Usually this fan gets clogged up with dust so the lamp temperature gets hotter than it should causing the thermal fuse to open up. Replacing the thermal fuse, sirrocco fan and cleaning the dust from the inside and fans will cure this. A Sony authorized servicer should be able to repair this for you. Good Luck
