      probably a bad LED. Can we see a clear straight shot picture from your PSU?

                          Help troubleshooting an audio problem with an RCA SGT-250 CED Player
                          by samson7point1@yahoo.com
                          The Problem: This player has a toggle switch to select between Stereo, Mono R, and Mono L. Regardless of the setting it outputs the sound to both the L&R audio jacks. In the Mono R position, the audio output level is normal (from both the L and R audio output jacks), in the Stereo position the audio output is about half the volume, and in Mono L, it's about 3/4 the volume. Something about putting it into Stereo mode is causing the volume to drop significantly and I can't figure it out.

                          The player processes the audio signal using two different reference frequencies. The "R"...

                          Samsung UN55MU6103F video problem; has colored stripes on the display
                          by alro7779
                          Hello, everyone!

                          A co-worker gave me a 55-inch Samsung TV model UN55MU6103F so I can try to fix the following problem... As soon as I plug it in to the wall, the TV turns on, and the display shows a few stripes all over the screen. I took off the back cover and disconnected both ribbon cables that go to the display (one at a time) so by doing that I can narrow down the bad section of the problem, but in both cases the display turns black. I know there are some voltages that I have to check (VGH, VGL, etc.) but don't know what reading each has to show. If anyone could guide me on this,...

                          Mi TV 4 Pro-Samsung Panel LSC550FN20 - Video problem, backlight and Audio works fine.
                          by SolarFlare
                          Hi,

                          My barely 3 year old TV has stopped displaying video, although the video output comes for a few seconds after turning ON which displays the manufacturers logo then shows the home screen (all this with some blue flicker) then the video goes blank and the screen is dark blue with the backlight on. The audio output works perfectly and the TV also takes in voice commands(smart TV).

                          The TCON board has the following Chips -
                          Samsung VTU63A0
                          RT6939 - 2nos.

                          and all these chips are getting real hot within a minute, I dont know if this is normal....

                          Samsung UN32M4500 has audio but no video
                          by frannyjunk
                          Hi, I have a Samsung UN32M4500 that turns on, has audio but no video. No Samsung splash screen when turning on, but I can see the backlights (screen is just this dark gray color). The TV only has one board, which I replaced from one I purchased from directtvparts on eBay. But still the problem persists. Is my LCD bad?

                          LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
                          by Hakuu
                          Hi There,

                          This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

                          After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.
