    47 philips pfl7432d, screen is dimming.

    I bought this for 35.00 and decided to attemp to fix it. Worse case, is i'm out 35.00. Not a bad risk. the screen lights up but it seems dim all over and one side is starting to become darker. Which leads to a couple of ways to address this. But, my wife now has my dmm and all of my tools. Yep, they are gone into the divorce abyss forever. So. I'm essentially starting from scratch here. I would like to get a inexpensive dmm. just to get by, until my resources are available to buy a decent one. ANy ideas on a cheap dmm?

    I'll been posting the pics tomorrow. and try to check out some voltages first. I will try to get the in voltages on the inverters first to see if the smps is pumping out the right juice, check caps on the inverters, and try to see what coming out of the inverter, if possible

    Thanks again,

      UPDATE: Found the caps on both the master and slave blown and leaking. Ordered the Panasonic FR caps and got them today. While trying to get the tv up so I can start to work on it, the screen cracked. . So to work on it is is somewhat futile. I guess the inverter boards can be fixed and the boards parted out. But I'm so disgusted right now, perhaps that will be another day.

        How did you crack the screen lifting it up? I've broken a screen before, but it took a lot more force than that.

          Actually Tom, I tried to "roll" or push the TV on the bed . It was positioned against the bed so I was able to pick up the bottom and dragged the tv onto the bed. And then I flipped it over onto the pillows so I could take pics before I started to work on it. I guess something could have caught while lifting it or it torqued enough to put a small crack in the bottom center. There was nothing on the bed, like a screw or anything like that. The other night it sipped from the wall onto the floor, but i started it up afterwards and it was fine. I need to mention the TV was made in 2007 and weighed around 75 pounds.

            Dell G3 15 3500 - Battery bug (black screen and flashing keyboard backlight)
            by HTR-Informatique
            Hello,

            YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo

            I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.

            On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.

            I also changed the screen because the PC fell and the screen was broken.

            I changed the battery with a new and original battery.

            I also had corrosion/oxidation on the...

            Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
            by Ryan.man
            Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

            My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

            This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

            iphone XS turns off when press on screen.
            by smic717394
            Hi,

            I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...

            Vizio E55-F1 dark backlight zones. LED failure or Dimming Zone Driver?
            by howardc64
            Problem

            Fixing a dimming zone TV with LEDs not lighting up. Dimming zone circuit introduces added variable to diagnose LED and/or Dimming Zone Driver board? Some 1/2 rows of LEDs appears to be out in active dimming zone off AND some brightness flickering with active dimming zone high while playing changing video



            Model & Board Pics



            Conflicting Spec

            Vizio indicate this TV has 10 dimming zones. However, LED strips and Zoned light driver connector suggest 12
