Re: Gateway FPD1530 works for a second then dark
There has to be markings on the caps it usually goes capacitance then working voltage.
Like 1000uf 25V.
Unless the caps are surface mount then they usually use a coding system printed on the top of the can.
Or they're a Nichicon HD copycat with no plastic sleeve in which case the info will also be printed on the top of the can.Elements of the past and the future combining to make something not quite as good as either.Comment

Re: Gateway FPD1530 works for a second then dark
Know it's been a few months since this was replied to, but for my 1530, the answer was to replace C106 and C107. They are rated at 1uf and 50v. Replaced mine with 22uf and 50v and things seem to be doing okay so far.Comment

Re: Gateway FPD1530 works for a second then dark
I have this monitor and it has the same on for 2 seconds then off,i use to have this monitor in a cold shop when it first started behaving this problem it would only do it while it was cold not when warm then it did it all the time, so i tried a hair dryer to warm it up and it worked. it would stay on indefinitely,if i shut it off it will still come back on,unless it cooled down,i would like to fix this thing any idea's why the heat would make it work and then stay on?Comment

Re: Gateway FPD1530 works for a second then dark
Usually caps are the problem...as the ESR reduces to a working level when there is some warmth around,and the unit will start. Problem probably on the Power board,change the caps and see if that sorts it.Comment

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...
