No. Never got it working. Had it soldered on. Didnt work so the set is now sitting behind a dresser In my spare bedroom. If you ever figure it out let me know.

Re: JVC lt-47x579 backlight comes on but nothing else
Ok. So the part came in today. Took it to guybi was going to get to solder it and first question he had was which way does it go? I showed him the picture posted by RON_CET here [url]https://www.badcaps.net/forum/showpost.php?p=252098&postcount=17[/url] and it still leaves me two ways of putting it on. In the picture it shows one of the little prongs blacked out. any help would be apreciated. Thanks.Re: JVC lt-47x579 backlight comes on...uybi was goingLeave a comment:

Re: JVC lt-47x579 backlight comes on but nothing else
Ok, so i took the board into an electronics shop that i have dealt with before, i had them remove ic2502. came home put the board back in, plugged everything in. hit power and nothing. I have the blue standby light on, but if i hit power on the tv or remote it does nothing. Any suggestions?Leave a comment:

Re: JVC lt-47x579 backlight comes on but nothing else
Hi tom66,
So, if i remove ic 2502, what steps should i take to test it? Is it just a case of removing it then powering on the set? And do you by chance happen to know somewhere i can order a replacement if this is the problem.Leave a comment:

Re: JVC lt-47x579 backlight comes on but nothing else
Thanks for the info. I did a google search to try and find that part, but everywhere i have looked it comes up out of stock. Do you perhaps have any idea of a source for this part where it would be stocked?Leave a comment:

Re: JVC lt-47x579 backlight comes on but nothing else
Hi RON_CET?
Thanks for the reply. However, if im being honest i really didn't understand all of what you said. I did understand that i should repace IC2502. first question, what and where is this? (i am aware that it was actually 2 questions.) next question, is there a way to test this or are you pretty sure thats the problem?
Im pretty handy with most tools, can read a meter pretty well. But i honestly dont have the experience with flat panel televisions to know what im doing without a little help....Leave a comment:

Re: JVC lt-47x579 backlight comes on but nothing else
the readings i get are.
the tab pin o.oo4v
the top pin 2.478v
the bottom pin 3.276v
I wasn't sure which was pin 1 or 3 so top is the upper most one in the picture you posted and bottom the lower pin. and the tab on the left.
this is with all the plugs connected and the set powered on..
the number on the reg is
AME8815
AECS250

Re: JVC lt-47x579 backlight comes on but nothing else
I don't see the attached picture, however I did just hook the tv up to my cable box with a hdmi cable. tried it in input 1,2, and 3. no sound. I verified that the box was on a channel with sound by hooking it up to another 32" lcd. And I can turn the tv on and off with the remote and the button on the side of the tv.
, ah, theres the picture. Will go test now.Leave a comment:

Re: JVC lt-47x579 backlight comes on but nothing else
screwed it all down, plugged all the plugs in, turned it on. I checked both sides of that fuse and got 11.58 both sides. I grounded to a screw in the frame.Leave a comment:

Re: JVC lt-47x579 backlight comes on but nothing else
o.k. Well the meter I have is one of the digital clamp auto-ranging kind. I set it to ohms, put the leads on either side of FP1. The reading I got immediately said 13.1 then went right down to 2.0 then slowly crept down till it said 0.4 where it fluctuated between 0.4 and 0.3. Now im not sure if this is a normal reading or if it is a problem with my meter. I could try and see if |I can get a hold of a different one.
also my meter does have the beeping sound for continuity and it was beeping while on the fuse.Leave a comment:

JVC lt-47x579 backlight comes on but nothing else
Hey everyone. Hopefully someone out there can help with my tv.
It is a JVC lt-47x579 LCD television, about 3 years old. Yesterday I got home from vacation pushed the power button on the remote. The little blue light on the bottom left comes on and stays on constantly. And the screen lights up with a bluish glow, which I assume is the backlight(correct me if i am wrong) I tried unplugging. left it unplugged over night, same thing this morning. I tried the vol + menu + power button thing, and no luck.
Next I took the back off the tv to check for any fuses, could only...
