Re: Help identifing a component on LG main board
Yes bad labeling i guess, that's what confused me in first place.Thank you for all your help. Only thing left now is to figure out where all the screws go since the tv came with a bag of screws from when the previous person tried to work on this tv and didnt find anything wrong with it so i managed to buy it very cheap

Re: Help identifing a component on LG main board
Thank you for the reply, you are absolutely correct, that the visual inspection can determine if something is bad or not, i will check the components of course but the visual inspection was how i found the burnt inductor. After the your post about the short i measured on the lvds cable to ground on the pins that connect to the burned inductor to see if there any shorts down true the tcon and panel but it didn't had any. I will take the tcon off again and check the elements on it for any shorts....Leave a comment:

Re: Help identifing a component on LG main board
Thank you for the answer, i was confused why the listed ohm rating for a inductor that's why i wanted to ask for help, i looked over the t-con board and it looks perfectly on visual inspection, no idea about the panel, its not broken anywhere or damaged in any way, the tv starts up and the backlight starts and stays on there is just no picture on the screen, i tested the fuse on the t-con and it was fine, how can i test the t-con and the panel to see if the problem is there. Thank you for your timeLeave a comment:

Help identifing a component on LG eax65040104 main board
Hello everyone, just got an LG 60LA860W that i'm attempting to repair. There is a blown component on the main board eax65040104 circled in red on the picture. After cleaning it i see that its marked L7201, i believe that's an inductor but the value given on the schematic doesn't help me to find a replacement. Can someone help me find a suitable replacement for that component please... -
Samsung PS50B450B1WXXH noise in the picture
Some time ago i got this Samsung as a not working tv to try to repair it, the problem was at the Y-main board, someone had tried to repair it before me and there was missing parts off the board including missing heatsink, i had few attempts at fixing the board but were unsuccessful so i got a new board from Aliexpress and the tv is now working but it has rally bad noise in the upper and lower parts of the screen, its especially bad in the upper left hand corner of the screen. Can someone tell me if this is fixable or the panel is done for. Thank you!... -
