    lCD TV Screens vs Laptop LCD Screens

    I see that there are many problems with TV tab bonds/chips on LCD TV but not on Laptop computers. I have seen laptops screens go bad but they are not made the same and seem to be alot more dependable. Am I correct to assume that they are made different due to larger voltages/currents for larger and brighter displays? Plasma TVs dont have the ICs in the tab bonds, at least on the sets that I have worked on. The ICs on the flex tab bonds sometimes rest against metal frames around the screen as a sort of heatsink.Why cant they just put the IC chips on the boards with a heatsink and use tabs like the Plasma set? The distance is only a few inches more, but maybe it makes a difference in high speed circuits.
    Question seems simple enough but I am not a engineer. Older TVs were alot more dependable but were lower resolution

      Does anyone know about 16x2 LCD screens used in alarm keypads?
      by Ady2017
      I have got an old Gardtec GT595 alarm which has got a faulty keypad with a failed LCD screen. This was apparently a very common problem with these and many people have had to replace the whole alarm because of this problem. Somebody claims to be able to repair the keypads by replacing the screen and I have tried it myself by replacing the LCD with a commonly available HD44780 1602 16x2 Serial LCD screen but it is not working. I am sure it is a problem with a driver or simular which is not allowing the screen to talk to the rest of the electronics. Does anyone know what this original screen was...

      Dell Latitude 5420, Coloured screens from one colour to another continuous.
      by Dan20701
      Hello all, I have a Dell Latitude 5420, before I upload the bios I thought I would ask. All I am getting is are coloured screens from one colure to another continuous that's all its doing.
      I have searched on google some say this is a graphics problem and not a bios problem. I did try another bios file from the forum it stops at the Dell logo.
      With the original chip fitted I am getting error code 3 amber and 3 white flashes.

      Any advice please ?.​

      fixing flat two tv screens
      by rookiecap
      I am trying to fix two flat tv screens. They have problems that I am not familiar how to deal with and if they are fixable at all.

      1) the first TV is RCA 32: LCD combo tv+dvd, model RLCDV3282A-B. It was distorting images in sync with sounds. The sounds were distorted too. Then it was shutting down automatically. I replaced all visible electrolytic capacitors on power supply board. After repair, the image and sound are restored but tv still shuts downs unexpectedly usually after couple of minutes. I do not know what to do next. What might be the culprit and how to trace/inspect...
