      screen flashing those multiple colour in sequence means no lvds signal. Check voltages at lvds connector and match with schematics.

          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...

          LCD TV Green/Pink screen problem
          by jimjoe123
          I have a Dick Smith 37" LCD TV, Model GE6804. I am using it as PC extended monitor only.

          Problem is while watching tv, I hear a semi loud click(like a electrical breaker tripping due to overload, just sound like it but no actual electrical overload), then screen is covered with green or pink. I can still see the original picture image but overlayed by green or pink. See attached images. Pink.jpg is what I see, and Normal.jpg is before green or pink screen, What I captured was pink screen, but about 80% of time it's green and 20% of time it's pink.

          Then each time...

          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...

          I need help with my friend Sony GDM-FW900 24” CRT
          by matthewmcconaughey
          Hello, Badcaps is my last resort. I am the first owner of the monitor. I reached almost every repair store in my area, but no one even wanted to hear about troubleshooting an old CRT monitor. At this point, I have been trying to figure it out by myself, but I have no idea where to start or look for.

          I wish to know how to think and locate a failing component. I will put all my efforts to learn and contribute.
          1. It started with a bright and greenish picture upon starting a cold monitor.
          2. About 2 years ago, only on the cold boot, the screen started to occasionally flash with

          SONY KD65x750F cycles through a white-red-green-blue screen when powered on
          by zukdj
          A new main board and power supply was installed on my TV last night, purchased the parts at ShopJimmy. I had no power before installing both parts. Now the TV powers on and I hear music as it cycles through a white-red-green-blue screen. I was thinking it may be a firmware mismatch with the parts however I am skeptical as to plugging in a USB stick with the newest firmware on it since I cannot do any user interaction since all I see is colors on the screen, will the firmware start and complete on its own once the USB is inserted or does it require user input? Someone told me it is in Purity Check...
