Re: LG 42LC7D PS Cap replacement help
UPDATE: Finally got the new power supply I ordered in the TV and now I am getting 5 or 6 GREEN flashes then the light goes solid green. Sometimes when I plug it up the screen flashes on and off real quick also.
So now I am getting a flashing green light when I was getting a flashing red light before.
What gives?

Orion SLED4668W no power
Looking for some guidance,
I replaced the power supply in this tv about 6 months ago after a power surge. It fixed the tv until recently when I quit working again. No red LED on the front or anything. I figured it was the power supply again and replaced it but this time that did nothing. I'm at a loss what to try next.

Re: LG 42LC7D PS Cap replacement help
I've replaced the caps on the power supply and still no luck. I'm not sure if I have another problem or my soldering skills are lacking (which they are). When I plug the TV in a can hear a definite click from the power supply and I get 5 blinks from the green LED on the front before it finally stays solid the 6th time. occasionally open plugging the tv in and turning it on I can see the backlight come on for a split second and go back out. The power supply clicks again upon unplugging the TV.
Does the 5 flashes of the light indicate...

I planned on replacing all Capacitors except those two big ones I just wasn't sure about the ripple current and impedance. I see those Panasonics I don't have a choice.Re: LG 42LC7D PS Cap replacement help

I don't think it looks the same. Let me upload pictures for you.

Re: LG 42LC7D PS Cap replacement help
Thanks for the reply. That brings me to another issue. I've seen the capacitor kits on ebay for this model of TV and I found it odd that they didn't have what I need.
You mention the two 2200uF caps on the board. My board does not have these. The caps I have are two big 450V 180uF, 3 1000uF 35V, 1 220uF 35V, 4 1000uF 25V, 6 680uF 25V, 2 220uF 25V, 3 22uF 50V, and 1 47uF ??V.
I've got EAY3273110 on this power supply along with a white barcode with I79BI327311020924
What do you make of this power supply...

LG 42LC7D PS Cap replacement help
Hi, New member here. I have searched for help with my question and although I have found a bit of helpful posts I still need some guidance.
I have a power supply (EAY3723110 ?) out of a LG 42LC7D TV that has 6 bulged caps. I plan on replacing all the caps with something of higher quality (Rubycon probably). I am relatively new to replacing these component level parts although I have done by fair share of soldering etc so I'm up for the job.
I made a list of all the caps and went to order from digikey when I ran into a problem. The caps have the UF and Voltage listed,...

Re: New Members - please post your introductions here
Hi all,
Kevin here from Tennessee. Although I've never had any formal training in electronics I've always been technically gifted. I do a lot of research online etc. Studied and received my amateur radio license at age 13. My real job is completely unrelated to electronics but I still find this type of stuff interests me. I've repaired 5 flat screen TV's in the last little bit just for fun and to pass the time. Looking forward to learning all I can here.
