    Re: VIZIO SV470M orange to white logo

    Just a guess but possibly a cold solder joint under the main video processor.

          Well put it all back togather and hooked it to cable and beautiful picture but No sound. So it looks like I still need a main board. Just can't find one anyplace.

                        Vizio E701i-A3 Vizio logo flashing then turns off
                        by Super360
                        Ok so here's the story. I was watching tv one day when all of a sudden I heard a pop from the back of the tv set and rushed to unplug the set. By this time the tv already had smoke coming out the back. It was not storming or inclement weather that day to cause a power surge to the best of my abilities. When I opened the tv up, I found that the three capacitors on the psu (highlighted in red) were all bulging and looked they had exploded. I replaced all of them right away and when I went to start up the tv after the "fix" it started just showing the flashing vizio logo as soon as power...

                        by noipi
                        i have DELL INSIPRON 14 5410 2-IN-1 blinking orange and white when charger connected, i tried to find Boardview or schematics but cannot find. i opened the unit and the motherboard model number is 203071-1 Watchmen that i found written on motherboard. Where should i start because when i press power on, nothing happens. but i checked the main power rails voltages are enabled and the charging for battery LDO is 3.3 volts.

                        HP Elitebook 8460p battery led white and blinking orange
                        by jorpec
                        Hello everyone

                        I have this Elitebook that wont turn on, only the battery led is white and blinking orange, does this even without battery.
                        If this is a error code i couldn't find any info about it.
                        Already tested with a another charger, measure the presence on 19v on the 19v rail, checked if there was capacitors in short-circuit

                        Thanks...

                        Vizio V555-G1 stuck on wallpaper; now stuck on V logo
                        by x_orange90_x
                        I just got this tv today and it's getting stuck on the wallpaper. When I first power it on it goes to the V logo, then a black screen for about 15 seconds, then a Chromecast error for just a few seconds, and then finally to a wallpaper. It stays frozen on this wallpaper and does not respond to anything on the remote besides power on/off. Likewise the buttons on the tv do nothing either (besides power). I did the "reset" by holding the volume down and input buttons together for 10 seconds. It showed a message at the top of the screen saying it was Wiping Data and would restart soon. After...

                        Vizio D32f-E1 Powers on, has backlight, won't boot/no logo, no menu or video
                        by JaquesPratt
                        I have a Vizio D32f-E1 LCD TV that does NOT have a TCON board.

                        This TV recently went through some 'death throes' and now won't boot. The first problem that began to manifest was while watching tv, the screen would 'freeze', and the image would dim over a few seconds until it was very dark. HOWEVER, the audio of the show would continue as normal. I could power off the TV for 5-20 seconds, power back on, and the video would be normal. This would occur 1-3 times when the TV was first started, and would not happen again after the TV was 'warmed up'. Not ideal, but this glitch was manageable....
