    Toshiba 32L2300U1 LED TV, blank screen

    Hello,

    I have a Toshiba 32L2300U1 LED TV. There is the red "Toshiba" logo when I first turn it on, then the screen goes blank within a second or two. Green light goes on, stays on. No blinking or anything like that.

    We bought this TV about 7 months ago for a relative, not long ago it just went out. She's quite a pill, so instead of trying to fix it and making her wait around for it, we just bought her a replacement and brought this one home to try and fix it. That being said, I have no idea what lead up to it not doing anything past the red Toshiba logo.

    Thanks in advance for any help!

      No firmware update for this model. Thanks though, I forgot to add that I'd already looked for that into the original post.

        I usually start with testing the power supply voltages, should be a legend with expected voltages by the connectors that plug in, unless you have an external power supply, as always be careful working with power supply, HIGH VOLTAGE, on primary side can be deadly. can test with digital multimeter in dc mode.

              Funai 32FL553P/10 - squealing from PSU, dies after 10 seconds, blank screen after logo, bootloops
              by kotel studios
              Hi,

              Found an Funai 32FL553P/10 TV on sale for cheap listed as broken, so I decided to give a shot at reparing this.

              State I got it in:
              Squealing from the PSU
              After logo I get a blank screen
              After 10 seconds of having a blank display w/ backlight the TV dies
              Give it 7-10ish seconds again and it starts to bootloop.

              What I did so far:
              Replaced all the caps on the PSU (apart from primaries, they were fine and none at hand)
              Checked all voltage rails:
              5VSB - 4.8V
              AMP+13V - 14.4V
              13V - 12.98V (in manual 12V)...

              A2141 Screen replacement. Boots screen freezes on Apple Logo 1/3 status bar unless connected to second monitor.
              by abajor
              Having this very weird issue.
              The owner of this laptop complained about screen being intermittent when opening and closing, and has been using the laptop on a thunderbolt video connection since the screen failed.

              I swapped with a working screen from an A2141 waiting for parts.

              The Os exhibits this weird behavior where it boots to to 1/3 the status bar, then it makes the boop sound. It's at the log in but for whatever reason the desktop isn't loaded.

              The laptop boots fine into recovery mode. I updated from Monterey to Sonoma and the laptop still has...

              HP Elitebook Screen blank - backlights but no image
              by dicky96
              Hi guys
              I'm trying to fix this laptop screen

              Basically the owner is a computer shop and they brought it to me with two screens. They said the repair shop they use could not fix it, so I thought i would try to see if I am better than their current repairer!

              OK so I have the original screen which works but has lines across the bottom quarter of the screen

              I have the replacement screen, which they fitted and it worked. They then put the laptop on one side for a couple of weeks until they found a buyer. When they showed it to the buyer, the screen would...
