Rather than make a mistake and feeding in AC I put in a DC 12v and nothing happened!!
Can you advise where I should jump 12v from and to on attached photo...so confident I'm doing correctly..

Need to check if correct!!! You say feed AC in...not DC?...Leave a comment:

Hey D......
Referring to earlier posts #24-27 are the low V and Resistance a factor?...
Apologies for my ignorance but you mentioned a panel test, could you clarify what you meant?
When investigating the possibility of damage to the Cof and apart from testing Caps is there anything else that I should be aware of? do's and don'ts!!

#Davi & all....I understand, can imagine following up various threads/forums as well as our day to day lives...must be a little brain draining especially with relatively newbies like myself hounding your knowledge.
Apologies for in and out with questions and queries to all who have taken time to assist, I expect time differences are a factor also, but still, much appreciated.
Regards
Long

Hi D......Sorry for delay in responding.
If I need to check the Cof or caps I've never delved that far into checking these components. They are taped down quite well and is there anything I should be aware of whilst removing and inspecting except for being extra careful as don't want to cause any further damage anywhere!
Where should I also test on the main board as you mentioned doing a panel test..to be honest I can't quite remember with any certainty which of the cables I changed at the time whilst the TV was still powered but I suspect it was the ribbon on the T-con side!

Put pins back, checked lvds and ribbons for continuity all ok-replaced and still no change. led's still working ok, tried other inputs hdmi nothing changed!
I began checking generally again in and around IC 302 and various caps associated seems that there maybe a problem with.....does this IC and buck converter have any affect or is this totally seperate. I compared to other power supplies and IC 300/3 are simular resistance and V but totally different to 302!!!
Also I'm only getting 0.3 v caps 604/6/8 and 5/7 1.8 v...are these correct?...Leave a comment:

pic 1-3
Hi all......
To save any confusion I've attached pics of my particular TV including PSU, Motherboard and T-con. I was in the process of removing the output ribbon 1 at a time...and this time i made sure that the power was off before moving anything. Attached is also where I originally taped over the ribbon to the left side off T-con output to remove slight vertical lines (little difficult to see on pic) which worked fine. Whilst viewing a little closer just in case of any damage which I hadn't noticed and then came across (pic 5) the right side input...Leave a comment:

Checked for damage....none that I can see...I taped up and secured the loose bezel.

Lg 47lm860v 3d tv- no picture
Re: LG 47 LM8600 - No Video Hi all.....
I probably need putting against a wall and deserve a stoning for my stupidity.............. I have a LG which after following information with problems with T-con and lines on screen covered the pins which affected the display and had it sorted...until!!! Lets get it over and done with, I managed to get a little sidetracked and forgot that the tv remained powered up and I replaced the LVDS which to my horror then left me with no picture whatsoever. The backlight remains ok but as mentioned no picture and probably managed to fry the T-con or have... -
Hi Davi......
Thanks for your reply...
As mentioned in your response I'll attempt your recommendation with my heat gun to see if helps.
I will also start a new thread which is what I thought I'd done but am still trying to get used to the workings of Badcaps!!
Catch up soon...and if you need me to explain a little clearer then please let me know.
regards

if you are referring to my comments then please ignore my ignorance as have messages from others that have nothing to do with my post!? Need to somehow change my notification settings.

Behringer Pro Mixer DJX-750
Hi all....I have been using my Behringer mixer quite comfortably for a number of years now and generally it's been trouble free apart from a replacement crossfader. Recently input three channel fader began to bleed a little and causing the mixer to light up like a Christmas tree! I realise the unit is ageing now and although I'd put some hours on it over the years it's not been abused. Following the issue I planned on replacing the faders and ordered the necessary parts. In the meantime whilst awaiting the replacements I continued to use the mixer up until the channel fader started to give feedback...
