    Let's Build a Better LCD TV

    Or

    How I Learned to Stop Worrying and Love my Television. 😁

    I bet we all have gripes about how current tv's are designed and built. Lets shame the manufacturers and put some improvements in a single thread. I'll start with two.

    First having to remove the LCD screen to get to the LEDs is a giant pain in the ass. They should have easier access. What if they were in tracks and could be slid out the side of the tv through an access hole after removing the back ? For that matter the LEDs themselves could be preassembled with a lens and a mounting device like a snap so you could pop them on and off in seconds. Imagine changing out all the LEDs in your backlit tv with just a screwdriver ?

    Secondly, I think things would be easier forgot all techs and hobbyists if the manufacturer would use all the same screws or at least as few groupings of different screws as possible.

    So what's your gripe/improvement ?

    Nope ... made to a price ,people wont pay extra just for the repairer's convenience

      Agreed, removable LEDs would increase the cost and selling "Easy to fix TVs" doesn't inspire confidence in the reliability.

        Also would result in thicker sets.
        esp as now they are using the back on the lcd panel as the actual back of the tv on alot of sets.

        Best would be just to increase the led count by 3 or 5
        would make it better, and the leds are pennies anyway.
        its silly why they use so few...

        And just limit the current.

          +1, Great idea about sliding them out the side, wonder why they don't make any like that, especially since led lit tvs are much less reliable than any tvs they have come out with in the last 50 years.

            There was a set on here recently where the led strips were easily individually removable from the rear of the panel which made an led, led strip replacement so much easier. If only all the makers could allow access to the leds this way.
            Willing to help but I'm no expert.

                I guess I meant this as an exercise from OUR perspective though some things carry over to the consumer. I know many people consider cost paramount but some common failures for which people throw their sets into a landfill might reconsider if they knew for a few dollars more they could have enjoyed their set longer because it was repairable.

                So I'll add another - replaceable cof's

                  And just limit the current.
                  Backlit sets need overhead already for the lenses - I bet someone could design a replaceable unit without adding height.

                  And there's no reason Edge lit panels can't be engineered to make those replaceable as well at least as a single strip replacement.

                  Your second point is of course valid as a means of extending functionality for current designs.

                  But it's just a thought experiment, don't be so serious

                    Replace the screen with an AMOLED screen and build it to last... done.

                    LCDs, etc. actually aren't that unreliable. I see many less faulty ones now. They've started becoming commodity items that last longer because a lot of the faults that afflicted earlier sets have been figured out.

                    This happens a lot in consumer electronics. Early models are reliable because they are overbuilt. Then they strip away parts and figure out how to make them cheaper. But they go too far and they start breaking. Then they fix them again, and since manufacturers find it hard to compete on features, they start competing on reliability and brand instead.

                      But of course the manufacturers will never tell you that they've gone too far before they stepped up reliability again

                        i invented a self repair tv . then one with user replaceable cards .like plug in replacements . then thought this is no use as they are all throwaway items and most folk want a new one when old one breaks down . they done it again and sold the crap first then made newer ones more desirable the industry is always far ahead of us consumers .

                          Motorola Quasar did this year's ago with thier works in a drawer. Cool concept, but replacing Vacuum tubes were still hard to get to when you have a fixed position fly back transformer and the HV rectifier and shunt regulator was still in a cage. Also the bad thing was, kids could open the drawer and if that happened, that would be bad...

                            Problem

                            This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                            by Pipolups
                            Hi there !

                            I'm having an issue for several weeks with my quite old K70 LUX RGB keyboard. I haven't used it for few months, and once I setup up again my desktop computer, I got several dead LEDs on that keyboard. I tried the Corsair troubleshooting thing (disabling options in iCUE, ...) but nothing changed so I conclude that for some reason some LEDs went in retirement...😅
                            Decision taken to change these LEDs as I have access to desoldering iron and binocular magnifier, I wrote a ticket to tech support, hopping to obtain the LEDs reference and... They refused to tell me 🙄...

                            So I use this TV daily as a second monitor for my PC or my Playstation - at one point a few months back I tried to fix the problem - but in the process, I figured out something that works so I haven't posted this for awhile. It is an annoying trick to have to do though, so I decided to post about it to see if anyone could spot what's wrong. It baffles me because it works on it's own half the time.

                            When I first got this TV, I was told it wouldn't turn on, and of course I did the flashlight test, and the image was there. Also, the red LED on the front indicated that it had power (it...

                            by Dobrowol
                            Hello. Ive got problem with Dell Latitude 3520. After power on, no display and fan goes crazy. Standard job, I exported a clean bios from update via pfs extract.



                            Steps i done and results:

                            I exported a clean bios from update file via pfs extract.

                            1. Build clean bios with clean ME, PMC, PCH in flash image tool.
                            Result: Dead

                            2. Build clean bios with no changes in ME, new PMC, PCH
                            Result: Dead

                            3. Build old bios with clean ME, new PMC, PCH
                            Result: The same

                            Replacing Mode Indicator LEDs
                            by VitalComputing
                            Hi all,

                            I have what should be a simple job but is causing me issues. There are three LEDs (yellow, green and red) on the indicator panel of a solar PWM controller and these have broken off. I need to replace them but I am unsure of the voltage drop across these. I don't want to replace with random LEDs in case they blow.

                            I took one of the LEDs out of circuit, put 19V across it with a 500 ohm resistor in series and there is a drop of about 13V across the LED, and this seems to increase as I increase the input voltage.

                            I thought I could just put a resistor...
