Re: Sylvania lc320sl1 wont turn on
did you check power button on the tv? if so what all did you check besides that? -
Re: Sylvania lc320sl1 wont turn on
your explanation is confusing... it says it won't turn on in the title then it says it works when plugged in...by works does that mean everything functions properly? and the only way you can get it to turn off is by unplugging the tv? so you have to unplug the tv while it is still showing a picture and it isn't turning off properly?Comment

Re: Sylvania lc320sl1 wont turn on
the tv turns on when you first plug it in and will play till you turn it off .then it will not start again till you unplug it and let it sit for a day then plug it in again .when its not working i get a green power light and when i push button light goes outComment

Re: Sylvania lc320sl1 wont turn on
ok i understand now. in order to troubleshoot it you're gonna have to take a good clear pic of all of the boards and individual pics of each board and go to manage attachments in the go advanced section and add them to your post then someone will be able to helpComment

Re: Sylvania lc320sl1 wont turn on
Re solder all inverter transformers then ohm them out when done. They should all read the same. Roughly 5 meg ohms.Did I leave the soldering iron on?Comment

Re: Sylvania lc320sl1 wont turn on

Re: Sylvania lc320sl1 wont turn on
Primary winding should show a low resistance. The secondary side will be much higher. There should not be a primary to secondary short. Just to give you an idea what to expect.Comment

Re: Sylvania lc320sl1 wont turn on
I have the same problem as soon as it turns on it shuts off when I turn it on the green light flashes goes on for like 2 sec then off it goes I looked at the boards and it doesn't look like any thing is burnt out or broken should I look for something in particularComment

Re: Sylvania lc320sl1 wont turn on
did you check these wires? you might have a bad inverter if those wires are ok. these sets with this setup seem to all have pretty much the same problems.

Re: Sylvania lc320sl1 wont turn on
I have one of these boards and the inverter transformers run about 4.75 mohm give or take but there is one that measures 4.55 mohm. Would that be a red flag? What is the percent over the others that would make it unacceptable? Thanks a lot.Comment

Re: Sylvania lc320sl1 wont turn on
I would believe that would be 4.75 MegaOhms and it would have to be secondary. ThanksComment

Hello, i have some issues with my laptop Lenovo Y700-17ISK (motherboard BY511 NM-A541), it started when i turn on the laptop, but the lcd wont turn on, i then connected it via hdmi to tv and screen was ok.

Conncted power supply and tuned on my laptop, the lcd turn on, it started to load os, then it turn off, after a second it turn on, then after like 3 seconds turn off again, and so on.

To all the members here...
Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.
So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But... -
Hello, I have an Acer Aspire 4520 from a couple of decades ago and I want to repair it solely for nostalgia.
It happens that when I turn it on after having been disconnected for a long time, it turns on without problems, it tells me that the BIOS has been reset and that it will load the factory settings, if I tell it to continue, the computer turns on and everything works fine.
The moment I turn it off and want to turn it back on a second time, or restart it and try to start it again, it no longer gives an image, and it no longer responds.
If I remove the... -
Hi everyone,
I am dealing with the problem of turning on and off my Dell e7470 notebook.
The battery charge light is solid white, I press the button, the power indicator and the light on the button are solid for 1-2 seconds and immediately turn off.
The system does not turn on, there is no post.
I removed the RAMs and changed them, changed the battery, RTC battery, AC adapter, removed them and waited, tried again, it does not turn on.
The problem continues in the same way.
I tried to turn on the Fn key, nothing came to the screen....
