    Toshiba 32DT2U bad main board

    I have a toshiba 32DT2U that I think has a bad main board. the tv will power up and the back liight works but I get no audio and no picture. is there a way to test the main board. I have tested for 5v 12v and 24v all are present. I have tested the f1 SMD on the main board and it is good. any help would be great thanks.

    Re: Toshiba 32DT2U bad main board

    Did you check the fuse and the voltage on the T-CON?

      I have replaced many main boards on this model. I would have to check my records, but I don't think I have replaced ANY panels on these.

        I don't think this TV has a T-Con Board. I think it is build into the main board.

          The T-CON is part of the panel then, the main board just send the LVDS to the T-CON on the panel. There will still be a surface mounted fuse and switching supplies and LDO on that built-in T-CON on the panel. Almost impossible to repair. It is built like computer monitor.
          Can we see the whole back side of the TV?

              Can you see any fuses on this board?

              Do NOT touch heatsinks when testing for voltages as they may be LIVE!

                Re: Toshiba 32DT2U bad main board

                Is there some tests that I can do to see if it is the main board or the T-Con.

                  The picture is not clear but I think I can see the fuse on the right side of the connector where red wires are on the connector.

                    I took a closer picture of this area. what do you think. I have tested and if that is a fuse yes it is bad. I get no continuity. what should I replace it with.

                      Re: Toshiba 32DT2U bad main board DEAD!!

                      well looks like this one has to go for sale for parts. I installed a new fuse and now I get many lines and a bright white screen. I think that means that the build in T-con controller is toast.

                        Hi and thanks in advance for any input you might provide!
                        I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.

                        Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this...

                        Sony xbr-65x900c main board issues?
                        by jb_Bak
                        Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

                        Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:

                        Issue: No Power, Then Rebooting After Main Board Change

                        Short answer: replace main board and power board
                        Technical answer: replace main board and Q306 & Q307 on power board.

                        Long answer:

                        TV wouldn't turn on. Power switch was fine which means the main board isn't processing the power on signal. Replaced main board. TV turns on now but randomly reboots. Bad main board? EEPROM? Tried to pull main board and got a shock touching the corner of the board. That's weird. C334 (450V 10uf) capacitor is still holding a high charge....

                        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...

                        Is it possible to upgrade from a Vestel 17MB97 main board to a 17MB110 Main board?
                        by cheeky2
                        I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
                        Obviously the same LVDS connector for the screen connection...
