    convergence problem 42h82

    My old Big screen tv started acting weird, the whole screen will sometimes be entirely horizontal lines (which they will switch from red horizontal lines to blue and back). I've read a little on this and what I am seeing is to replace the SMT caps, and was wondering how do you identify values on SMD caps?

    the caps I am looking at replacing are:
    u4
    100
    16v

    2b
    10
    16v

    t1
    100
    6v

    i am assuming theses are all 16v and 6v, 100uf and 10uf, but what does u4, 2b, and t1 mean???

      is that your toshiba with this notorious model? yes mostly the 10uF SMD caps are the responsible for this. Also change out 100uF and some 470uF. I use standard radial caps and legs bent outwards and trimmed and soldered to the pads, standing up. Also it is vital that to resolder whole convergence area including the wire jumpers on the circuit board (small signal mainboard) near inductor coils.

      Cheers, Wizard

              i think i accidently ordered non-polarized 10uf caps for my original xbox. will this cause a problem?
              by bulkchart32
              i ordered a lot of caps from digikey to repair my xboxs. one thing i ordered was 50NXA10MEFC5X11-ND caps and i think they are not polarized. will this cause any kind of a problem? i really don't want to order new caps just because of this.

              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...

              Hi. I have a problem that has been going on for some time (2-3 years). It's hard to explain what it really is. Sometimes, my computer stops playing music, stops videos (starts buffering on youtube), there is no sound in games and when I minimize the game window and return to the game there is a black screen with window borders...

              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....
