We'll there doesn't appear to be any bad solder joints that I could see but I will recheckall the joints today after work. That would be an amazinglycheap fix. There definitely are no bad looking caps that are bulging or leaking. If i get it to power back up whereally should I check for stby on the connector or board somewhere else?...Leave a comment:

Side note, I just moved the unit back out to check voltages on the board, screwed the power supply board back in and reconnected the wires and plugged it in screen down, and wouldn't you know it the damn thing came on! V logo was on, powered it down, set it up right and grabbed a chrome cast and repowered it. Came up and no errors or flashing lights! Ran it for about 2 minutes and then it went off again and won't power up again.... Is this just bad caps most likely? Should I really cap this bad boy and if so which ones would...Last edited by Biffm17; 02-07-2016, 10:01 PM.Leave a comment:

Yes, i did read post 46, with this board, I was not clear which pins were the standby pins or if there was an of place to check for it. This obeisance a large TV which is apart in my living room and the wife isn't too happy having it there... so I will try and look for more voltages .Leave a comment:

No flashing lights errors of any kind and no standby light. I was not too sure which pins were standby which was why I was asking. They are numbered and was looking at them but their pitch are very close and don't want to short anything out and make it any worse. When I have the set plugged in and back off I can hear a very slight faint something like a human or possibly a buzz for about a second then stop the start back up then stop etc... But it is almost inaudible and never really had my he'd behind it with the back panel...Last edited by Biffm17; 02-06-2016, 05:03 PM.Leave a comment:

Re: Sharp Aquos 70" LED LC-70LE632U does not power on
What are the voltages I should be looking for and where to measure them? I have the same issue with no stand by light and the set will not turn on. It just stopped while watching it and did this a few times at random the months b4. I do have 120 VAC after the fuse and was seeing around 15 vac on a few caps. I really don't want to buy a board if I can find the culprit on the board! Thank you.Last edited by Biffm17; 02-06-2016, 11:37 AM.Leave a comment:
