    It depends on what circuit it is being used in, if it is in the power supply then it will have higher ripple when load tries to draw more current. Right now he may not see the artifact on the video but may be certain condition he may see the effect on the screen. If he can live with it and his eyes are not good enough to notice any thing on the screen then he can leave it.
    I am not sure if you are old enough to know about Muntz, read about his TV.
    http://www.madmanmuntzmovie.com/?m=2
    https://www.autodesk.com/products/ea.../madman-muntz/
    Exert:
    Then came the TV years. Muntz thought the television sets on the market at the time were far too complicated, so he experimented by buying an existing set, disassembling it, then removing parts one at a time. If the set still played, he removed another part. Then another and another. Finally, with the set simplified as much as it could be, it became a Muntz TV! And these black and white TV sets, the smallest of which sold for $99.95, breaking the $100 price barrier for the first time, became some of the hottest selling consumer products in America.

              good you noticed cracked cap. and all of those connected are do one job only discharging lcd pixel. in short you should after replace cap need to preform the set playing over flew item like live football to be sure there are smooth display-- this thought only with adjust measurement Gama camera will done not just human eyes. sorry to tell this for me non repair.

                        Have the same problem with this tv, measured the voltages and went through the chart in the service manual > states to replace faulty t-con.
                        Now the problem, how to replace the t-con board.

                        I would appreciate it if someone can tell me how on how to remove the bronze colored panel ribbon cable from the TCON board that seems to be connect at the other end to the panel, without destroying it. I hope to then fix the ribbon cables on the new TCON board.
                        The cables look like they have been glued on to the TCON board. I've attached some pictures to hosw the cables. Any help would be appreciated.

                          NO do not remove that, what they are referring to is a stand alone tcon board, what you have there is not and you are right, removing that will pretty much ruin the tv.

                            by DKWS89
                            Hey Guys,

                            So a few months ago my Sony XBR 49x900e TV screen stopped displaying the picture but the backlight comes on and I still get sound when I use the remote and navigate to certain apps. I haven't checked anything with the meter yet but started with ordering some replacement boards. I've tried replacing the BMKS board (used from ebay) and also completed the firmware upgrade based on Nicks TV repairs youtube video. I've also replaced the TCON (twice) and PIB.

                            All of these changes have resulted in the same issue with no picture. I've also tried disconnecting the ribbons...

                            Trying to Save - SONY BRAVIA KD-75X780F - No Picture BUT there’s sound
                            by KYBOSH
                            Previous owner said TV just went blank one day.
                            They attempted to open the back panel and yanked the power connector off the power supply in the meantime.
                            Easily fixed that and got the TV to turn on. Backlights come one with everything connected. Good Sign.
                            The mainboard shows signs of life (red light on digital audio out is on) but that's about it. Good Sign.
                            There is not blinking LED and the most importantly there is LED response and sound when I press the MENU button on remote control. GREAT Sign.

                            I just downloaded the Sony KD-75X7800F Service Manual and...

                            - when it arrived, it had a picture for a few seconds
                            - it keeps rebooting
                            - without ribbon cable between the two panel boards, it does not reboot but I have no picture
                            - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
                            - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

                            Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
                            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

                            I have a Sony KD-43XE8005 with no picture on the TV when powered on. Audio and backlight work ok when powering on. Solid white indication light showing on front of tv bezel.

If I gently rub the ribbon cable on the right an image or purple black bars appear. The cable doesnt appear damaged, and if swapped with the other ribbon cable the same flickering symptoms can be seen.
