    Fujitsu Siemens Myrica V32-1 - backlight, but no image

    Hi all!

    I just got this, presumably defunct TV for free - and it seems that the backlight works, and the TV turns on just fine. No image ever appears, and i can't seem to get it to work with either VGA, SCART or RCA video. (RCA+SCART seems to be connected to another board than VGA and DVI). I opened it up, and i can't find any obvious bulging caps.

    I found another thread describing what i think may be the same as my problem: https://www.badcaps.net/forum/showthread.php?t=17990

    So, I took out the power board, and it seems there is brown marks around both sides of one of the diodes - is this normal or do you think this is where the problem is? Look at the attached pictures.. :-)

    The power board is a PSM192-240, and i found a replacement @ ebay for about $50 incl. shipping. Should i buy that and hope that the power board is what needs replacing? (I'm in Norway and nowhere near a radioshack - so it's hard to just go out and buy the right components! :-( )

    Thanks a lot! :-)

      The first two suspects are

      1) bad component on the logic board or bad logic board
      2) blown fuse on the t-con panel

      We need pictures of every board on your TV. The t-con board may be hidden behind a metal shield. The t-con is usually near the top of the tv.

          Thanks a lot for the reply! :-)

          I'm sorry if therse are the wrong boards, i don't know what a t-con panel is (yep, noob here!) but maybe it is the one on the left in the picture, under the plastic cover? Should i rip the plastic cover off and check? (I can't seem to figure out how to remove the large panel where most of the boards are mounted - it seems to be glued to the frame or something??)

              1) Your t-con is likely in the area circled in red. Follow the cables circled in yellow. They likely are connected to the bottom of the t-con.

              2) Do you have a multimeter and are your familiar with how to measure DC voltage and resistance?

                  This looks like an OEM TV made by Funai (searching for t32134). The service manual looks like it has the same boards.



                  http://elektrotanya.com/funai_lcd_t2.../download.html

                  I only downloaded the first one and took a quick look.

                      Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                      by Tynan Dill
                      I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                      Upon bringing it home and plugging it up, it showed a standby light.

                      I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                      The screen seems to blackout and stay black, but with a flashlight I can see the display.

                      With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                      Assuming...

                      Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
                      Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

                      Panasonic TC-P54VT25 No image. A or D board?
                      by canadaboy25
                      I have a Panasonic TC-P54VT25 that will power on and prime the display but there is no image at all.

                      The panel is primed as there is a slight glow from the entire panel. This means the problem should be logic related. The service manual also confirms this and recommends replacing the A or the D board.

                      I have tried to get the TV to display the test sequence but I have been unable to and I don't even know if this TV has a test sequence or not. I tried following tom66's instructions in post #3 on this thread https://www.badcaps.net/forum/showthread.php?t=26790. There was...

                      Philips 65PUS8518/12 distorted image after main board replacement
                      by tuner2000i
                      hello everyone,

                      I don't normally do tv repairs but this is a case with my personal TV which got fried together with many other electronics in my house after a thunderstorm.

                      The TV is a Philips 65PUS8518/12 which had no power. I measured and concluded that the main board was probably fried through ethernet or hdmi. I found a board with same number 715GD328-M0F-B00-005Y (I had G) but from a 55PUS8518. The TV starts but the image is doubled, distorted. I need to set the panel code which is 016 according to the sticker on the back but I can not seem to do it.

                      ...

I don't have another edp cable, but i measured it with meter and it comes out good...i am baffled......
