Backlights are not generally expensive but I wouldn't suggest you repair it yourself unless you've opened up pc's before....you'll need a service repair manual to do it yourself as, at the very least, you'll have to remove the screen bezel (usually 4 screws) and then detach the screen from the hinges (again usually 4 screws).
I would suggest getting a couple of quotes from repair centres.
As far as backlight goes it either works or doesn't (like a light bulb) sporadic use usually means a bad connection rather than a blown light but it would still need to be opened up to check the connections...again needing a service manual and a technical person

Samsung UN40H5003AF, tv has audio but no picture, no backlight that I can see. With Flashlight I can see the menu screen. Is it worth fixing and can a novice like myself do it? Thanks


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electronicshelponline.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main digital board./

No image on my laptop screen only on an external monitor


LCD panel,cable or inverter are faulty.Inverter and CCFL backlight check is shining a torchlight across the screen to see if there is any image in the screen.This doesn't isolate either problem but can provide testing options.If it is an LED panel no option but to replace if backlight issue.If you don't have spare parts to test with you are stuck though.If you are a novice in repair it could cause more problems by damaging/breaking parts in attempts to fix.

The microwave unit on my Thermadore CMT231 (integrated microwave convection oven) has suddenly stopped functioning. I suspect a fuse has blown. Is this a self-serviceable part? I am a complete novice, but...


No to novice work! get yourself or your family killed (although you might do Darwins' work for him.....)

Yes to fuse, check the HV fuse and try replacing it. if it blows again you have a serious fault and need a micro tech.
PS expensive :-(

Tv doesnt turn on...just clicks


the relay is clicking on. it mave have bad contacts internally. this controls the power supply for the audio and video circuits. you may just have a blown power supply fuse. since you are a novice. recommend service by tech should get an estimate 1st. shouldn't be too expensive

I have a Insignia NS-LCD26-09 that the backlight appears to have failed. I can see the display but is very dark. One day it worked and the next day it did not. Is it worth fixing?


Check eBay for a new backlight bulb. If you are willing to do the work to replace it, it is up to you how much it is worth. (I am poor so would fix it myself)

Screen dark, but intermittant. Is it backlight, inverter or other


I always start with replacing the inverter since it's much much easier and is usually the source of these problems.

If that doesn't work you could replace the backlight ( not fun or easy for a novice) or replace the entire lcd.

Best of luck!

Long delay before comes on


Honestly, this does not have any real affect on the future performance or operation of the TV so it may not be worth investing in unless you are very bothered by it.
The backlight is something that is not easily repaired by a novice and extremely expensive to repair in general(more or equal to the cost of a new TV).
Good news is that these manuals are written by people who don't have an exact concept of how the words are interpretted. For example, the manual says "the backlight is failing" which means the backlight should be replaced. I am sure it was meant to say "the backlight components are failing" which may mean only a board or small compenent that affects the backlight needs replacing. This may be much cheaper.

Screen broken


If there is definitely a cracked display then only solution is to replace the LCD panel- this is NOT for the novice having said that I was once a novice..I guess I still am:) the LCD panel as its quite expensive for joe ordinary to buy you may have luck locating a used one but be careful out there..its a minefield
