Then properly post a picture of the bottom of the board. I suspect you have a totally different monitor.

The monitor is indeed a Gateway FPD1530

I'm not sure why, but the back board pic isn't working

Re: Gateway FPD1530 works for a second then dark
I believe the picture limit size is 2000x2000. You can crop out your carpet in the pictures to lower the size.
In addition, the owner of this forum has been making changes in the last 3 or 4 days, but has not posted a notice that I'm aware of, and the site has been up/down lately.

Re: Gateway FPD1530 works for a second then dark
1) DMM in diode test: Test diodes D15, D16, D12, D8, D14 both directions and post results
2) better pic of bottom. Take clear closeup of the entire right half of the board (side with discoloration). And I'd prefer they not be posted inline, just attached with the thumbnail...Comment

OK... I see how it's done now. I thought I had to add the image from the attached files to the text area with the IMG tags or they wouldn't showComment

Re: Gateway FPD1530 works for a second then dark
What are those diode readings I asked for?
Note: To get clear pictures, you need to do the following:
1) Put the camera in Macro mode (Usually identified by a flower)
2) Turn off the flash
3) Use sunlight for light source
4) Take picture directly above board, not at an angle
If it's still blury, use a tripod or steady you hands against something firm.Comment

Re: Gateway FPD1530 works for a second then dark
I don't have any knowledge of how to test things or what readings go with what. I don't have anything to test with either. I mainly was asking what the two 1Uf caps mcfischer was referring to when I first posted in this thread.Comment

Re: Gateway FPD1530 works for a second then dark
The 1uf caps in the first post are at location C106 and the one just left of it (just above ZD101).

Re: Gateway FPD1530 works for a second then dark
Look at the picture in the very first post. It near the very top in the middle right by the Delta.
That is why PlainBill wanted pictures of your board. It looks like the picture in the first post and your board are NOTHING alike.
It is not uncommon for different board revisions to exist in the "same" monitor.

Re: Gateway FPD1530 works for a second then dark
That explains alot... I have a completely different board in mine. In fact, the power wire and video cable are soldered right to the boards. No connectorsComment

Re: Gateway FPD1530 works for a second then dark
Now that we are all on the same page, check
1) glass fuses and picofuse to see if they are open
2) test transformer using ohms
3) check for cracked or poor solder joints
for starters.

I ended up just chucking the monitor to the recycling center. I replaced the caps and still nothing. Now back to trying to fix the little Dell 17"Comment

Re: Gateway FPD1530 works for a second then dark
How do you know what volts they are at? There was another monitor with repair of the 680 uf cap needed and the cap read "25 V". But these are too small and have no writing on them that I can see. Maybe I need a bigger magnifying glass. Anyone know what is the voltage on this one or is it important, what range will work?
Thanks!

Re: Gateway FPD1530 works for a second then dark
The voltage is written on the cap, but you may have to remove it from the board to actually read it.
The voltage of cap has to be the same or higher than the existing one. For example, if the cap is 1uF 25V, you can substitute with a 1uF 35V.
A clear focused picture ALWAYS helps.--- begin sig file ---

Was watching this set, and suddenly it went dark. Picture is still visible, just very dark. Tried checking all settings, adjusting brightness to 100% no change. Reset through menus, no change.
bought used boards from ebay (power and input boards) replaced with same results, changing brightness does seem to have a slight affect.. but not to normal visibility of picture.
I'm handy, fixed TVs before.. I can't see any issues with boards... hoping someone can point me in the right direction to properly diagnose. I don't believe the LEDs are caput, since the picture is on and equal... -
Hi all
While I have quite a decent background in electrical & electronic troubleshooting & repairs, this is my first time stripping down an LCD TV for repair.... I have inherited a 3yr old Panasonic LCD which has a picture, but it is quite dark (too dark to be watchable - but still quite easy to see; I didnt need a torch to see it).
I started by checking and trying to adjust all of the picture and backlighting levels, but that made little to no difference. I also did a factory reset.
From there I envisaged that the backlighting wasn't working, however... -
Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.
The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.
Original T-con:
Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.
First replacement T-con:
I thought it might be t-con and ordered new t-con from china(supposedly tested)... -
This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.
Problem
TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode... -
Hi, I have a Samsung UE50TU with:
- sound and backlight, but no picture
- when it arrived, it had a picture for a few seconds
- it keeps rebooting
- without ribbon cable between the two panel boards, it does not reboot but I have no picture
- without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
- when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.
- without cable between mainboard and lcd panel and with a jumpered...
