    Olevia 537-b11 wierd problem.

    The set will turn on and display a picture for 10 min-30min. Then the remote and buttons stop working. Then after a while, the set turns off.

    Saw a couple of swolen caps on the power supply so I replaced all of the cold side caps with Panasonic FM and FC. No change.
    All power supply voltages are correct, stable, and ripple free. I checked all the regulators and all are spot on. There are no labels on either the power supply or the other boards. Electrotanya doesn't have a manual, but I think I have located the Pwr on line. Maybe I'll try a resistor to hold it up. I'm thginking Main board, any thoughts? Anyone have the service manual?

    Did you check the capacitance and ESR of all the other caps? If you used a hair dryer you might be able to find what components are causing the fault more quickly..

      Now I can't get it to do a channel scan either. I'll try yhe hair dryer tomorrow.

        Truep, did you ever have any luck finding the problem with this set? I picked one of these up and it seems to be having the same problem. I will randomly power off, sometimes the controls stop responding (remote and on the set), sometimes the picture will display wrong, etc. Most of the time when it powers off it will just turn right back on if not a hard power cycle will get working again. With the exception of the main cap, I replaced all the Elite craps on the power board thinking that was the problem but it did not fix this set. I did not touch the UCC KY caps. I have to get it back from my parents house as I took it over there before thoroughly testing it after the recap.

          I sent the main board to moduslink for repair but haven't received it back yet.

            Thanks for replying!


            Did using the hair dryer point you in the direction of a particular chip or did you just send them the board and say fix it? Do you have a cost estimate on the repair?

              Problem with LG Plasma 60PM6700 - Random power downs
              by theone111
              I have an LG Plasma TV 60PM6700 for the past ~12 years.

              In the last ~3-4 months I have been having some issues.
              1. Problem: It started with random picture disappearing (sound still worked).
                Frequency: Happened about once a week.
                Solution: Had to turn off TV wait a few seconds before turning it on again.
              2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
                Frequency: Happened about once a week.
                Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
              3. Problem: TV shuts down

              Thinkpad X1 Carbon "LMQ-1MB 12298-2 48.4LY26.021" VCC3M problem
              by Zeonalbasta
              i have a problem with thinkpad X1 carbon gen 2 "LMQ-1MB 12298-2 48.4LY26.021"
              The laptop was turned off because the MOSFET was not transmitting voltage. After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly. However, there is another problem, even though the voltage has been supplied to the laptop, it still won't turn on, there isn't even an LED indicator. After double...

              Lenovo T580 - LCD Panel problem - error 0288
              by perzyk23
              Good morning,
              I have a problem with Lenovo T580, which after error code 0288 suggests a problem with the display. I checked the display and it works on another laptop. I replaced the display cable with a new one. I programmed another BIOS (downloaded from this forum) and I still have the problem of a dead display - there is an image via HDMI, and the system does not detect the built-in LCD at all. The problem appears to be hardware. What can I check to confirm or disprove this? I found many threads on the Internet related to this problem 0288, but without specific solutions. Please advise....

              Dell 15R-5521 keyboard problem (KBC?)
              by SDNarcia
              Hello, I have a Dell 15R-5521, with the problem that the Ctrl, Alt, Shitf and Num Lock keys do not work, I tested the keyboard with a keyboard tester and it is functional, I also got another new keyboard and the computer has the same problem with the same keys. Check continuity between the ZIF connector from the keyboard to the KBC and all pins are correct. I cleaned the ZIF connector and the KBC and I still have the same problem. I reinstalled windows just in case, and it didn't work. I updated the BIOS to the latest version A16 and there were no changes.

              As additional information,...
