Re: LG 47lv5500 no picture, possibly no sound
Okay, I tried to do what you said but I am guessing I failed. I could only get readings on ic506 and ic507 but I was getting a reading of 48 ohm not .4....

Re: LG 47lv5500 no picture, possibly no sound
When I had tested for ohms, it was just between the fuse and those components. I just checked now for the other end of the ribbons cables. The cable at P1502 (not sure if that is how you describe it, the one under "reverse") I get no resistance but at the other cable there are some pins where I can get it give me around .4 ohms....

Re: LG 47lv5500 no picture, possibly no sound
Hello. I have finally been able to get at least one of the part numbers. I can't seem to find a magnifying glass and my eyes are too bad to read the small print. I was able to use a macro lens but I still can't make out the number for ic508. You can see them in the picture. For ic504 I see: 2132MP -2.5G1 027J97
All I can see for ic 508 looks like: A27173 1043GGE (though I am not sure if any of that is correct).
Here is my question, is it pointless to replace these since I can't get the full...

Re: LG 47lv5500 no picture, possibly no sound
Okay, I am able to get get voltages from ic504 and 508 but I can't seem to get any ohms. I don't know if I am doing something wrong or if that just means that they are bad. Also, though I am getting voltages, I still haven't found a datasheet anywhere to let me know what the voltages should be though I may have found a place selling them. Should I just order them?

Re: Lg service menu 42ld420-za
Hello. You can try this:
Press and hold the {MENU} button ON THE REMOTE until a 4-digit password screen is displayed.
LG Service Menu PIN/Password Codes
8 7 4 1
8 7 4 3
7 7 7 7
0 0 0 0
8 8 7 8
0 4 1 3
I found this using the following site: [url]http://www.factory-reset.com[/url]
It lists ways to access the service menu for different brands though they don't always work for particular models.Re: Lg service menu 42ld420-za...

Re: LG 47lv5500 no picture, possibly no sound
Okay, these are the results I got (hopefully I tested it right):
For continuity, the fuse is shorted (the meter beeped)
As for voltage, I was getting around .85 - .88 for each side. Obviously, nowhere near the 12V I should see.
Does this mean the T-Con board is bad or a different board?

LG 47lv5500 no picture, possibly no sound
I currently have a 47lv5500 that doesn't get display a picture. The TV had a broken screen when I first got it. It took me a while to find a replacement but was finally able to do so. The person I bought the replacement from said that it was working (can't remember if they said if it was new or not, it was a while ago). Because of family issues, I wasn't able to transfer anything over for a few months. When I finally did, the TV would turn on but no picture would/will show. The screen will light up when turned on, go black for a second or two and then go back to just displaying a lightened screen....

Re: New Members - please post your introductions here
Hello all. My name is Michael. I like to fix electronics but don't know how to do the real specific stuff (i.e. replace a capacitor). I usually just have to replace a whole board instead. Hoping to be able to learn here how to do the fancy stuff.
