      Those do not look like low esr caps, just generic ones.

          Change all the little electrolytic capacitors too, if you haven't already.

              Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
              by Tynan Dill
              I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

              Upon bringing it home and plugging it up, it showed a standby light.

              I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

              The screen seems to blackout and stay black, but with a flashlight I can see the display.

              With my Playstation 4 connected via HDMI, and running a game I can hear sound.

              Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock
              by sam_sam_sam
              I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

              This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

              After all of...

              (SOLVED) - ONN 100012588 No Power, Then Rebooting After Main Board Change
              by JDC
              ONN 100012588
              Issue: No Power, Then Rebooting After Main Board Change

              Short answer: replace main board and power board
              Technical answer: replace main board and Q306 & Q307 on power board.

              Long answer:

              TV wouldn't turn on. Power switch was fine which means the main board isn't processing the power on signal. Replaced main board. TV turns on now but randomly reboots. Bad main board? EEPROM? Tried to pull main board and got a shock touching the corner of the board. That's weird. C334 (450V 10uf) capacitor is still holding a high charge....

              Tankless hot water heater controller board not powering up when power is applied
              by sam_sam_sam
              I recently bought a used tankless hot water heater and the controller board is completely dead no power up when power is applied the display board works however the main controller board does not work correctly at all the fuse is good

              I bought a used replacement controller board that also had issues that I was able to fix and now the tankless water heater works correctly now

              However I would like to know if I could figure what happened to this controller board if possible

              Tomorrow I will take some better pictures of both side of both boards

              The...

              HP RP7 RP7800 from 2012/2013 worst fault - has "character"
              by Rayblaster
              Hello friends, I've got a nice toy to play with - it is an HP RP7800 All-in-one POS system. I got it for free and it has one problem - it turns on very rarely, and just for a few seconds. After that it dies and doesn't come on if I don't leave it unplugged for at least 2 hours. I've repaired motherboards before, this is not my first one, but problem with these types of faults is that everything you check on the board will usually be fine. This is the case for me here.

              I dissassembled it completely, and got my hands on the motherboard. Model No. is PIQ67H/Higgins 11047-I 48.3GD02.011....
