Sceptre X24WG Problems

[ng7m]

Hello, I'm the original owner of a Sceptre X24WG (24 inch of course) monitor and it started having trouble 18-24 months ago... I set it aside for awhile and tried it again the last week or so. I get a nice picture when it's first turned on, but I have a green vertical line on the right side of the LCD. See the pictures. When it first went out, after it had been off for a few days, I tried it again and thought it was working and then after awhile it would go out again.

I have tried to read up on the forum here before I posted my problem. I have a lot of pictures and I took voltages from the 11 pin connector. Hopefully I'm providing good details as a new guy here on the forum.

After the monitor has been on a while, it will start to get some pixels in the lower part of the display that turn green... random on the display and then after awhile the display with flash a bit and then eventually go off. It may work for 30-60 minutes.

The pictures of the caps etc... are below... I hope I didn't post too many pictures and I tried to keep them less than 1meg each.

Here are the cap details and voltage details (two different monitor resolutions and the monitor really had not been on very long) The caps all look fine and I'm not seeing any discoloration on the board or any solder joints that look suspecct or cold.

Any suggestions would be helpful! When I found this forum, it motivated me to try and fix the board. Why not right... Thanks, Matt

Caps as identified on the board:

#1 C551 470uF 16v
#2 C552 470uF 16v
#3 C553 470uF 16v

#5 C662 470uF 25v

Re: Sceptre X24WG Problems

This is a failure of the LCD panel, either the 'panel card', drivers on the flex conductor that links the panel card to the glass LCD panel, or a bad bond between the flex conductors and the panel card, or (more likely) between the the flex conductors and the glass LCD panel. All are considered unrepairable outside of a shop that specializes in such repairs.

In short, your options are to use it like that, try to find a good LCD panel, or sell it and buy a new monitor.

Re: Sceptre X24WG Problems

PlainBill, thanks for the quick reply... well, it looks like it's not worth the effort with the cost of lcd monitors these days. And all those pictures I took and uploaded along with checking the panel output voltages Better to know now and not mess with it anymore.

It's tough to find a 1900x1200 monitor these days... everything is now 16:9.

Well, thanks again!

It's not a problem. Buy a 24" 16:9 monitor. It will be slightly higher than the old monitor. Cover the right 1/4 and it's like you just went to a slightly larger 4:3.

Re: Sceptre X24WG Problems

Matt (ng7m),

It is years later, but what is the full description of the monitor:
Sceptre X24WG - 1080P
or
Sceptre X24WG - Naga
or
something else?

I have the 1080P
