I have never heard of the inverter board conflicting with speakers.
1. My guess would be that you possibly loosened a cable? when you opened you laptop… sometimes the sound cable on the right or left side runs along side the video cable that enters the monitor bezel.
2. Another option could just be that your speakers or one of your speakers is shot. You would then need to replace them, just as your would any other part on the computer.

hope that is helpful.
God Bless

Hi Mr. James Chao,

that is a perfect symptom of? a bad inverter.
I would feel 100% comfortable telling you to buy and replace it with a new one.

just took a look at your video. was wondering if u know anything about the compaq pesario c700 models. i replaced the lcd cable? and now have a backlight problem. was wondering if i didnt replace the inverter right after I took it off. i noticed the the inverter board is supposed to touch the foil pieces One of them touches but dont know where/how to place the second foil piece. does this also mean I have to re assemble the entire screen assembly to see if it works properly? answer please..

I do not know specifically about your laptop model.

There is a chance you loosened your inverter cable. I would check the monitor ones first (in and out of the board) then I would check the one going from your mother board to your inverter.

If you replaced a? ribbon cable, that may have damaged your inverter cable where it goes through the bezel joints. You can use a tester to find out.

Your inverter may need to be replaced.

I don’t think you’re foil would directly affect the

I dont think you’re foil would directly affect the inverter. If so? you should at least see it light up and then flash or turn off. The foil is just for extra grounding. Most new laptops do not even have near as much as old ones do.

Hope that is helpful.
God Bless,

Was just checking out your video with the Toshiba inverter repair. It so happens I have that same laptop and that same problem. There’s two questions I have to ask. First, what type of tools do you need to open the laptop screen? Second, Did you have to completely remove the screen out to remove the old inverter or did you just do it the way you did in your video that all you had to to do was remove? those two little wires from the side of the inverter and remove it like that? Thanks.

Hi Carizion,
not tricks in the video:
1. remove 4 rubber screw covers
2. remove 4 screws in front bezel (small tip philipps)
3. remove the screw holding the inverter in place (small tip philipps)
4. unplug the 2 inverter cables
5.? repeat the process backwards

That should be all. Remember to remover power supply from charger and battery.
Thank you

Thank you for this video – lots of helpful tips.

Dropped my laptop, and over the course of a week, the screen progressively became darker, until one side lost all backlight, and then the other. Bought an inverter on? ebay after watching this, and fitting it went very smoothly (except for one absolutely tiny screw holding the interter in place; nice one Dell!).

Thank you.
