I have finally found the video that solves my problem. Thank you for putting in the effort and energy to make this informational video.

[@cadeirafilosofica]

I changed the capacitors and it worked for me. Thank you a lot!!!

Wonderful video thank you

Just smack the power supply and it works

100 💯 you are telling the truth I gave my tv a good slap and it hasn’t turnt off 👍🏿

[@davidjnunnelee2566]

I have to do that to mine. But it only works for a couple minutes

Great video and thumbs up. I have this SHARP and when I power it on, I see half the panel light up then go off. I have taken it apart and tested ALL the LED strips and they check out. I have stb voltage as well as 12 vts. I am puzzled with this problem. Might it be the PS causing this, or is the problem coming from the main board, and how would I separate the two boards when I need them connected to fire up the lights? Appreciate the assistance.

[@addiengr1]

which sharp type do u have. needs to check diagram. supposed another 3 or 5 volts to run the main board. beside the stb 12 vlt.

[@vityok3000]

I got 60pn6550-ua turns of at arround 30 min room temperature than turns back on by it self in like 9 min and it happens over and over different timing. My main board has 1 capacitor like that. Ill try to change it if i find a good substitute in another broken tv

[@nilsfrahm1323]

wait, replace with new capacitor, as old ones have liquid that evaporates and may not be very good...

[@TheRajeshmalik]

I have same TV. It was getting of randomly first day after 1 hours, next day after 30 minutes and next day in 5 minutes. I checked all outputs 15.5V, 12V, 5V all were fine before and also after problems persist. Then i checked the same board as your one it was having corrosion on multiple locations by atmospheric reaction on copper. I have done cleaning and now working up to 30 minutes. More I will check later if again do problem.

[@itachiuchiathesoulking6553]

My problem was my power outlet I had to much things connected to it so it use to put my tv on and off. Got it change and the problem was fixed!

The average household allows 12 operating, not counted if they are off, devices before overloads can occur.

[@tyronebunne2220]

Great stuff.

[@vint.k1727]

Cool i think ill try somthing like this w. This polaraoid tv i have ( check the cap itors and board for faults w. same on/ off by itself problem when plugged in. Ive got nothing else to lose other than a already broken tv wasting space for months on end.

[@ProdiJoee]

Why did you decide to replace that specific capacitor on the control board?

[@addiengr1]

Its from Indonesian electronics forum. its tested that smd caps has leakage.

Is your tv running porn at approx.4:50? Lol

[@svetlinkarachorov4208]

So I've had this issue on two separate TV's. The problem was not the capacitor and the problem will come up again. Once you unplug the TV's power for a little while the problem disappears temporarily but it comes back. The real issue is the physical buttons on the TV. They seem to malfunction randomly. Just unplug their connector from the motherboard and the issue is fixed for ever for free. Best of luck to you all.

[@haziq7885]

do you now how to identify the connector? im facing the same issue right now.

[@sukisuki6753]

Worked but now my remote does not work.

[@svetlinkarachorov4208]

@@sukisuki6753 See if the connector for the buttons is the same as for the remote receiver. If so I would cut just the wire from the button on the TV. (Do that at your own risk)

[@svetlinkarachorov4208]

Bro I have a problem also with my tv it turn off and on I did everything with it nothing is working I even unplug the power cord but nothing works and it does not even connect to wifi as well and it has gotten slow also I can't scroll to other apps plz if you can help me with this problem

[@addiengr1]

try search by your TV model number. try also different language /keywords to search in youtube. also forum electronic discussion. solution may different for each brands and model.

hi all...i got the same problem and same tv...the problem is the heat...if you loos the screws (as much as need) the hit will get out and wont turn off the tv...hoop it helped ..love:)

[@danmurray7976]

Which screws?

Which screws ? Sir ?

[@tayisofficial6243]

i had to put a fan it was over heating now i going to have to check the capcitators

[@shanenoel1270]

Your solution sort of helped me. I actually just turned the TV off for a while ( had to unplug it from the wall because using the power button didn't work as it came on again). I let it cool down and turned it back on....fixed! Thanks! I wasn't about to start unscrewing things : - )

[@nilsfrahm1323]

Might be right. If capacitors are old, as chips in the tv heat up, air temperature increases and liquid electrolite from capacitors turns to vapor. This decreases capacitor capacity, which makes circuit turn off, probably unstable voltage. If hot air can escape, it will work longer or may work ok. This indicates a design problem, they should have put fan or metal heatsink on the back, or heatsink to the metal frame, but didn't and this kills the tv slowly, by running components at high temps.

[@KaptainCanuck]

To discharge, simply unplug the device and hold down the power button for 5-10 seconds. It is better than shorting out an electronics circuit. Any time the device is plugged in, do the same thing before working on it again.

What would cause a plasma TV, to make a clicking sound lose all power. My tv comes on. It works for about 3 minutes. Power saving mode is off.

[@addiengr1]

power supply board may have problem if no power at all. check fuse. caps. rectifier. what type plasma you have?

[@davidjnunnelee2566]

@@addiengr1 it gets power. It works for about 8 minutes then shuts off and loses all power.

My tv is same model but i dont know if same issue ..turning on after few minutes my tv is still shutdown :(

[@addiengr1]

follow the second step replacing 1 capacitor (video 5:50). if still shutdown, replace the capacitor in power supply. its a common problem

[@josephrexortega125]

Ill try your method sir . :) Thank you
