Re: Need some help with a MAG LT782s LCD

Re: Need some help with a MAG LT782s LCD
Well, I got some time to try what you said. I tested the points and they both were really close, not enough to matter. I tried testing the CCFLs and they all looked the same brightness. I went a step further and tried every CCFL on every plug, first just one then both. They all did the same thing, power on with green led then 2 seconds the screen goes black with green led. I can change the resolution and the screen with come on again for 2 seconds then goes black with green led. Is this the CCFL driver side of the board going in to a protective...Leave a comment:

Re: Need some help with a MAG LT782s LCD
It's been a wile and I haven't forgot about this. I was on vacation. As of now, I don't have the time to work on this monitor. I should have some time next week thou and will post my findings. Thanks for the help so far, I hop I get this thing working. My HP monitor has a half inch blob of dead pixels in it due to something hitting it. It still works, but is annoying the heck out of me. It is now a shop monitor for PC repairs (system reloads mainly) and what not.Leave a comment:

Re: Need some help with a MAG LT782s LCD
All right, got the new caps in and soldered. I have replaced all the following caps.
power side
5 x 470uF 25v
1 x 220uF 25v
inverter side
2 x 10uF 50v
2 x 100uF 25v
It is still doing the 2 seconds on then black screen with green LED. It will come on when changing resolution then do the same thing. Any ideas?Leave a comment:

Re: Need some help with a MAG LT782s LCD
Yes, that is the brands. There are no series that I can find except for the 470uF which doesn't mater. I'm getting ready to buy new ones but a friend has some 470uF that are JACKET brand and said he would sell them to me for $5 or $6. I have uploaded a pic of them (pic is from ebay, but they are identical). Is that a good brand? If not I have been looking on eBay for some more. I have told myself if I get to $25 or $30 in parts, I'm done trying to fix this. Not going to spend half the price of the monitor to fix it when I could spend that...Leave a comment:

Re: Need some help with a MAG LT782s LCD
I could swear that I posted the brands here. Anyway, here is what I used.
5 x Fuhjyyu 470uF 25v and 1 x Taicon 470uF 50v (only had 5 25v and the next one up was the 50v)
2 x Chang 10uF 50v
2 x Jaro 100uF 25vLeave a comment:

Re: Need some help with a MAG LT782s LCD
Here are some more pics. I found a neighbor with a digital cam and took some new pics. Its only a 6mp but better than my phone.
Had to use imageshack due to the resolution being to big.

Re: Need some help with a MAG LT782s LCD
6 x 470uF 25v with 5 x 470uF 25v and 1 x 470uF 50v (only had 5 25v and the next one up was the 50v)
That is what I replaced before I started replacing some of the inverter side components. I didn't replace the 220uF 25v because I didn't have one. As for the cracked LCD, it only has one CCFL in it (one connecter). It came from a HP laptop. I have noticed that a lot of the laptop LCD screens that I have replaced just use one CCFL instead of two.
I have another LCD here that I fixed a wile back. It got hit with a surge...Leave a comment:

Re: Need some help with a MAG LT782s LCD
Sorry for the late reply, been out of town for a couple of days installing a security system for work. Anyway, I have attached the pics here. As for the pics, I won't have the digital cam back for 2 weeks, parents have it on there vacation (I need one, lol). As I said, I took them with my cell. It has a 5 megapixel cam in it (thank you droid). I can take more if needed, just let me know. Off to bed again, but no work in the morning unless called in (I hope not)....Leave a comment:

Need some help with a MAG LT782s LCD
Hello to all.
I have a MAG LT782s LCD monitor. I got this free from a friend's shop. This start out as a "some times it works" to a "deader than you know what".
First thing I did was research. I found this site and found that some people did a cap replacement. So, I did a cap replacement with some caps I had. The power board model is AD-1700 REV: F from Mirage Electronics dated 1,14,2005. There is also another number on the board that is 200-000-1700B VERSION: H.
Here is what I replaced.
6 x 470uF 25v with 5 x 470uF...
