    42lc55

    I got a LG LCD tv that I've had for about 3 years maybe more. Recently, I heard a loud popping sound from the speakers and and a slightly fuzzy picture, but now the picture won't even come on at all. There is power going into the tv because the green light is on but there is no picture, I can't even press the buttons on the remote to open the menu or anything. I usually leave the tv on overnight so it may have overheated or something. I've heard a lot of people talking about replacing the caps. Is this the problem?

        Re: 42lc55

        It's bad capacitors - same with the 42LC46 series - and is an easy fix. Replace the 35V or 50V capacitor on the board (filters power for the audio) as well as the four 2200u 10V.

        I picked up a 42LC46 from the local dump and fixed it. Had similar symptoms - wouldn't power up from standby or intermittent power up after left alone for 15-45 minutes.

            I saw the response but decided that I would help anyway. One more TV saved from landfill is another victory, howsoever gained...

              I see you point. How do you get on with picking them up? I would imagine they are against people taking things away?

                  I buy them and the guys at the local tip keep the money, although it is all on the record (signed book) so maybe they don't?!

                    Jesus!!

                    Reading this I am glad I didn't let my ego get in the way of the reply I just made on your Samsung post Jasgriff. This had me in stitches!!

                    Selldoor - Hi welcome to the forum - I have been told that I am rude and sarcastic so I will try and go easy on you.
                    Rude and sarcastic, maybe, maybe. The response you received PRICELESS! At least you were upfront and honest.

                      T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)
                      by Tr0ll
                      Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

                      The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

                      Original T-con:
                      Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

                      First replacement T-con:

                      I thought it might be t-con and ordered new t-con from china(supposedly tested)...

                      SAMSUNG UN55KS9000F picture fades then distorts into vertical lines after 20 seconds
                      by JJAAMM
                      This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

                      Problem
                      TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...

                      Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
                      by TR103
                      Hi, I have a Samsung UE50TU with:
                      - sound and backlight, but no picture
                      - 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.

                      - without cable between mainboard and lcd panel and with a jumpered...

                      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 β€˜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 β€˜new' Tcon board this time, and

                      Hello, Last week I bought the 50" Sony X80j tv everything was working fine, untill I plugged the tv in a ups power supply 650va the tv remote control became unresponsive and the TV became laggy after a while the picture quality isn't the same as before the tv seems less brighter and the picture is somehow blurry, people's faces don't look as natural as before, there is a mini orange-pink tint to the edge of people's faces especially in NETFLIX Dolby Vision like in One Piece ep1 Alvida skin tone, my intention was to protect the tv but something went wrong I checked the ups with a multimeter,...
