    Re: Friends Sharp LC-32SH2OU Fades to White

    So the scaler board does not appear to be the problem. Same symptom with the new board after about 2 minutes. Something new that I noticed. I had it hooked up to the dvr and when it started to fade I tried fast forwarding and I noticed that the picture was frozen while it was disappearing.

    I've looked on eBay for the T-con board but what I'm seeing online is not what I'm seeing in my tv. Is this board underneath the other boards? Do I have to take the metal sheet off to get to it? Also, I see no reference to a t-con board in the service manual.

    Is the video board giving me the issue or do I need to totally dismantle this tv?

      According to these photos there is no T-Con board on this unit. There's a Power PCB, a Scaler PCB (which is what I've already replaced), a Digital PCB which is mounted to the AV PCB and there's also a Remocon PCB. Is the Remocon PCB what you're referring to as the T-Con?

        Now... there does appear to be an Inverter Board that I'm not seeing on the diagrams in the manual...

        Update: There is no reference to the inverter but I am seeing it on the left side under the LCD cover.

          See what the T-CON board looks like:
          http://www.shopjimmy.com/catalogsear...harp+LC-32SH20

          You need to lift up the LCD cover as shown in pic #2 of post 22, then you need to remove the metal shield to get to the T-CON. This set is not designed to be easy repair.

            Found one on eBay for about 3x as much as that site you had the link to. I also found it on the TV. Wasn't too bad getting to it or getting it out. Looking at it I don't see anything that would indicate that anything is blown but I guess it's possible that static electricity or maybe a power surge did something to it.

            So I will order the board and hope that it fixes the problem.

                Is that what you're seeing right away? Not even good pictures for seconds? If that is the case, this replacement is worst than the original one.
                What do you get if you put the old one back in? all the cables are seated back properly?

                    Yeah, this was right from the get go. I will check the connections tomorrow but I am quite sure they're all tight.

                      Must be a bad T-Con board. I checked all of the connections, turned the TV back on after I had it assembled and got the same results. Put the old T-Con board back in and it worked like it did before I switched the board. So it is a bad board.

                        Got the new T-Con board in last week and now the TV works beautifully. So is this a common issue with these boards? Should I order a couple extra just in case this one dies on me?

                          Sharp LC-65Q620U White Screen
                          by EazyBone
                          Another TV topic!!
                          I got this sharp TV that when I first plugged it in it showed the sharp logo and then went to the input screen. This was about 30 seconds and then it showed white screen. Now I can't see anything but white screen. This has a separate TCON and Main.

                          The TCON is getting 12V and several parts are as well but the VGH line is only .5Volts which I thought is totally incorrect.

                          Am I on the correct assumption that the TCON is bad somehow if I'm only getting that voltage or is there something else I should check?...

                          SHARP LC-60LE640X display flashing white noise patches and totally dropping out randomly
                          by dmcabs
                          Hey guys,

                          I have a SHARP LC-60LE640X TV that has suddenly developed an intermittent fault of flashing white noise patches (appears like an Analog tuner off signal) and then totally dropping out.
                          This model I believe is also known as LC-60LE600U or LC-60LE640U in other regions.

                          FYI, a long time ago I was a component level repair tech for all consumer electronics and IT equipment.
                          I'm a bit rusty but still have ability to dig right down.

                          I measured all power supply lines and checked them for AC ripple voltage. Noting any lines that exceeded about...

                          SHARP LC-70UD27U black and white lines
                          by zoontz
                          Wondering if anyone has addressed an issue with the SHARP 70” LC-70UD27U having thin black and white lines running from left to right horizontally on the screen. I snagged this TV set from a neighbor since I have been successful in repairing numerous other TVs. I assume this probably happens to other TV sets and may have been addressed in another thread. If so please point me in the right direction.

                          What I have tried so far.
                          I have tested all HDMI inputs with the same results.
                          I have checked for firmware updates.
                          I have reset to factory settings.

                          Sharp LC-40LE830E white blinking after wallplug is off
                          by bajdik
                          Hello, on Sharp LC-40LE830E is everything OK. Working great. If I put the 230 V off and on again, it just blinking white standby LED. I can power on only via VOL- and CH+ and POWER button on TV. After that, I can power off and power on again without problem (by buttons or remote control) until the 230 V is connected. If i put the plug off and on again, just white standby LED blinking. TV needs three button starting again.. On the first look, the backlight looks great, no darker or lighter spots. Any idea what is wrong?
