    Toshiba 32HL67US sound/good backlights/ black screen

    Toshiba model # 32HL67US chassis # TAC0749
    This television will power on, I can here sound and tell the backlights are on but the screen is black.
    This one of my first attempts at a television I hoping someone could point me in the right direction.
    I am really not up to speed on the proper names for all the boards.
    I did a search and found what I think may be a similar problem, it was recommended to check and see if the fuse on the Tcon board was good and that it's getting the proper voltage through the fuse.
    For right now I just posted an overall shot of the set and if needed I would be more than happy to provide more.
    I am just wondering if I should disassemble to get to the Tcon or are there some other things to check first?

    I tried searching for Elektro Tanya for a service manual; I found something that may be it.
    But I cannot figure a how to download the manual, Am I missing something?

        I found the download button, and was able to download the ZIP file and extract it,

          someone just copied the toshiba online service manunal website which requires a tool to open the files.

          http://www.tv.quuq.org/forum/index.php?topic=3278

          tried it and it only seems to work properly on XP and IE6 with loose active X settings.. ridiculous

                PDFs (or perhaps I should say the common PDF readers) aren't a particularly good solution when you want to reference several different pages at the same time. Although somehow I doubt Toshiba's solution would be much better.

                  I don't know if this changes anything but I tried a different input and it has the same effect.
                  The screen is still dark but you can see that the Backlights are on; it looks different than what I see on a computer monitor when the fuse is blown.

                    Is this the T-con board? Or what is it?
                    There were a lot of screws but it wasn't that bad, Fuse #1 has gone open, I have quickly checked so capacitors in its area, and none appear to be shorted, I am hoping I will get lucky and have working TV for the price of a fuse.

                          tab bonding issues maybe?
                          (the connections from the flexcables to the actual glass panel)

                              Be careful with the link in post #5 ,I ended up with a Searchq search engine and toolbar, the toolbar was easy to get rid of but, it was still buried deep somewhere inside my computer. And it’s very annoying
                              I may have checked a box that I shouldn’t have when I installed it, I don’t know,
                              Just be careful.

                                      by Mgiffune
                                      I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

                                      I ordered a supposedly ‘new' Tcon board this time, and

Possibly bad T-Con RUNTK4244ZZ or panel? Could main or power supply cause this? There were 2 blown 560u 35v on power going to backlights but they were still working fine. Thanks for your help.

                                      Good morning.
                                      I have a problem with my LG Smart 43UF640V TV. It starts, the backlight comes on but nothing is displayed on the screen and there is no sound.
                                      I thought it was a TCon problem and ran various tests. If I disconnect one or the other of the cables from the tcon to the panel then the screen is white on the side where the cable is disconnected and black on the other side. If the two cables are disconnected the screen is completely black.
                                      In the 4 configurations I measure exactly the same voltages on the tcon card (model V15 43UHD TM120 Ver0.4) :

                                      Hello.
                                      I have this issue on my Samsung EU55JS9000T TV.
                                      Backlight is good when the one connect box in not connected to the TV and I can launch the TCON screen test with the remote control.

                                      But when I connect the one connect box the backlight immediatly turn off, the sound is OK (TNT source).
                                      I dont know if the problem is from the one connect box or from the internal motherboard of the TV.
                                      I open the one connect box (reference BN96-37087R) and all seems good, simply the Hawk-P CI is very hot after 5 minutes (~65 degres).

                                      Is someone have experience...

                                      Hi it looks like everything works don't know where to test except the 390v in the 2 capacitor in the hot side of the power supply and the weird 180v in the diodes in the cold side that should be discharged it is writin on the circuit no more you can read what is written on the circuit quite srrange color mixiing yellow and white
                                      anyhow i couldn't t read anything else
                                      the backlight is on strong and the screen does not get dark or very dark but no pictures
                                      the mainborad feels a bit hott on the black part i test it to 52 degree's against 34 to 40 on the rest of it
                                      ...
