I wanted to ask some question about your post --> [url]https://www.badcaps.net/forum/showthread.php?t=51587[/url]
I'm facing the same problem but my voltages are a little bit different.
If you can answer my few questions I'd appreciate that.
Thankshttps://Hello,<br />

Re: Panasonic TX-L42B6B – LED Single Blink
Thought I'd post again just to close this thread and to let anyone with the same problem know what happened (I hate threads which just end).
Well I got an inverter board and that made no difference so the service manual was right, it was the panel. To prove it I got busy with my screwdriver and got to the LED's :-
I was hoping to attach a video, which shows only the three middle strips flashing. The top and bottom strips are in series so that fits. Checked continuity and that was OK. Found... -
Re: Panasonic TX-L42B6B – LED Single Blink
Does anyone think it might be the Inverter board ? When Panasonic say that the panel is the fault I wonder if they mean when the screen incorporated the inverter instead of being separate board.Leave a comment:

Panasonic TX-L42B6B – LED Single Blink
I was given the TV by a relative who had already put it outside in the rain ready for landfill, luckily it was screen side up & at an angle so I was able to fully dry it out (I think). Immediately on applying power the standby light flashes very fast (16 times I think) then goes steady for several seconds, during which time the screen flashes, trying to start, first showing four blank screens then a pause followed by another blank screen & then three screens on which I can see “No Signal” then another pause followed by another blank screen & three more “No Signal” screens.... -
Re: (Regal Brand TV) 32" LG LED display Beer Damage (LC320EUN) (Pictures inside)
I put 6870s-1172a into Google and several Chinese sites show part of the board but sadly not the part you want. There is a Polish site which, if you look at the translation, is also about a liquid spillage. There are some images but you have to sign in to see them.Leave a comment:

Re: LG 32LT75 - Leave Well Alone or What ?
I hope you don't mind, I checked the other marked voltages. The 3.3V ON measures only 1.39 with the TV on (zero with it off). On the other connector:-
19v is 20.1/20.2
6.5v is 6.34
3.4v is 3.44
12v is 12.07Leave a comment:

Re: LG 32LT75 - Leave Well Alone or What ?
The 6.5v measures 6.34. (so I didn't need PSON - but where is it out of curiosity) - oooh forgot to say, TV is on OK.Last edited by Scotty16; 07-25-2012, 12:26 PM.Leave a comment:

Tom - I noticed there where two ST5V so measured them both - 5.09V, spot on I guess.Leave a comment:

LG 32LT75 - Leave Well Alone or What ?
My Mother purchased a LG 32LT75 TV (with built in 160 GB PVR) in Nov 2008 for about £550. From day one it gave problems, but my mother just put up with it (see this thread [url]http://www.avforums.com/forums/lg-forum/672666-lg-32lt75.html[/url]). To cut a nine page post short it boiled down to a combination of software upgrade (finally had this done Feb 2011 - LG did for free since known fault) and the digital switch over (Mar 2011 I think). Just got it working right when it developed a not switching on fault/switching on with sound but no picture (Jul 2011). LG refused to repair it (must have...
