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?

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 out

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 help

Re solder all inverter transformers then ohm them out when done. They should all read the same. Roughly 5 meg ohms.

sorry i have been away. these coils are on backlight board? right they ohm out at 2.95. should i ohm them off the board?

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.

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 particular

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.

Re: Sylvania lc320sl1 wont turn on

I would believe that would be 4.75 MegaOhms and it would have to be secondary. Thanks

Re: Sylvania lc320sl1 wont turn on

I have the same set and the same exact problem. green light flashes like it is going to turn on the words digital television appears for about 1 second and the set turn off and the red light comes on. I have checked all the wires and found nothing wrong. any other ideas?
