    LG 55LV5400 55" LED TV, very slow refresh rate

    One of my co-workers has a tv that is just out of warranty and has a very slow refresh rate. Ironically, it is similar to this he says (http://www.youtube.com/watch?v=0GB1dEtHxDE). He is asking $150 for it. My question is, I am new to tv/monitor repair but not to repairing electronics. Is this something I should take a risk on, and do you think it is fixable for a reasonable amount of money.

    As a teacher, I wanted a hobby for this summer, and I think it is going to be repairing TVs. If someone could give me some insight on what they think the problem might be, I would be very appreciative. Thanks.

      This is probably a tab bond problem. Same effect here:

      The problem can be difficult to permanently fix. $150 is too much in my opinion because you can easily damage the panel when repairing it. And don't underestimate how truly massive 55" is. Very difficult to work on...

          Hey, just curious if you guys ever figured this problem out? I have the same problem with a 55LV5500, its only 2 years old. I looked at all the tab bonds and they all look solid, and i cleaned them off etc.. didnt know if there was anything else i could do to diagnose.

              Could you take a video of the problem perhaps?

                      Can't find the pics of the Sony tab bonds , but here are some of a Samsung I did. I do the tab bonds with the set standing with only the bottom screws holding the frame. I found doing it that way I can check with the frame on the picture over and over with no chance of the glass panel moving , and getting broken.

                          How To Stop CRT Flicker
                          by TechGeek
                          [PART 1 OF 2]

                          Ever gotten a CRT monitor and noticed an irritating flicker?

                          Here's how to get rid of it (or at least make it far less annoying).

                          Method 1: Increase Refresh Rate
                          1) Get to your display settings. This varies from OS to OS.
                          For Windows (95 to 2000, XP to 7 with Icons Mode, XP to 7 with Classic Start Menu
                          (NOT Classic Start))
                          1) Open the Start Menu
                          (For 95 to 2000 and XP to 7 with Classic Start Menu)
                          Click "All Programs", then "Accessories", then "Control...

                          I finally got one too! a new monitor! and my first ips panel to boot!
                          by ChaosLegionnaire
                          after bigtroll managing to score a new video card in this thread, i thought i'd get a new monitor too, since my current one has a bubbly and blurry screen that i posted in this thread.

                          i tried numerous local websites to get one but many required a mobile number to sign up which i dont own. i also had issues finding the right monitor that met my requirements. it was a nightmare finding one, spending weeks looking through g00gle.

                          finally, i decided to try lazada, the singapore version of jack's aliexpress. it only required an email address for signup, but whenever i...

                          HP x360 Chromebook 14A-CA, DA00GIMB6H0 REV:H, flooded, restored, slow and stuck in tablet mode
                          by modtool
                          Dear colleagues,
                          I've entered the repair of the chromebook machines just one month ago and I've found some significant differences from the classic laptops or macbooks, so I'm searching some advices.

                          The owner of this chromebook gave it to me after it has been left flooded by water for almost a week, so chances of repair were not so high, the mainboard was oxidyzed in many spots but I made a nice cleaning, resoldering and component replaging work and now it is almost working.

                          Among other things I've cleaned many spots from oxyds, reballed CPU, EMMC, EC, replaced...

                          MacBook Pro A1708 - CPU extremely slow, locked @ 0.39ghz; fan full speed
                          by gjlpereira
                          Hi forum.

                          I'm working on a macbook pro, model a1708, that is running extremely slow.

                          Everything on it seams to work just fine, it just works extremely slow; painfully slow; especially running macos (windows and linux actually run OKish on it, slow, but usable).
                          One other symptom of the problem with the machine is that the fan is always running at full speed.

                          This machine has been worked on by someone else previously; they tried to repair it, but with no success. The motherboard does have sings of being worked on, but it all looks good/OK; like...
