Hi. Yesterday I noticed that my 4 year old philips tv was getting a bit dim, and then it just went pitch black while the sound / sky was still running. I even put in on and off and the problem continues. I read about using a flashlight and did that, and I could very faintly see some of the tv stuff, so I am assuming that it is something to do with the backlight? Please can you advise me on how I change the backlight and find Philips replacement parts. Many thanks!
Hi @moso0202 You will need to open up the tv to check inside. Since you mentioned that when you shine the flashlight on the panel, you see the image, you will need to inspect the backlight module inside the panel. Handle with care as the display module is fragile Some Example https://www.youtube.com/watch?v=DBH6-Eqn… Jump to video 1:50 to test with a multimeter. https://www.youtube.com/watch?v=sIuS6ZSr… Below is an example for the parts, for your reference, if you need, i would suggest to search further, e.g. price + shipping to your budget. https://www.aliexpress.com/i/40004008952…
@moso0202 since you can see your screen with a flashlight you already determined that this is a backlight issue. Two things that can have happened. It is either your powerboard not putting adequate voltage out to your backlight LED’s or the backlight LED strips have failed. All you need to do now is to remove the back cover from your TV and take some measurements at the backlight connector (marked CN8101 on your board). Set your voltmeter to greater than 120VDC and put the red probe ((+) on pin . Black probe (-) measure on pin 3,4 and 5 let us know what it shows. After that, red probe on pin 12 and black probe to 8,9, and 10. Let us know what you get.Post some good images of your boards with your question so we can see what you see. Adding images to an existing question I am not sure if Samsung is a better brand or if there are really any great brands out there. I do know to stay aways from Vizio, TCL, Sony and Toshiba’s. Anything after that is a go for as long as the price is right.
