messed up on inverter board
I desoldered two fets and used the small screwdriver...pulled 3 solder pads off. what is the easiest and best way to fix. I am sure Kranksaft,DaveMax, or Kc8 has a solution for this. I am a novice at this. Just started two months ago. Have recapped three mobos and 1 lcd monitor. They are working fine. Any help would be appreciated. Will include pics soon. Need new bats for digital camera. Broke now cause went to casino in Biloxi, MS over July 4th. Thanks for any help

Re: messed up on inverter board
If the pad is completely gone, then I sand off the track it was connected to - the thin 0.5mm edge of fine sandpaper folded on itself possibly to reveal the copper, then paint using ~99% conductive silver paint or a conductive ink pen connect it to the exposed track and paint a new pad, let it dry and repaint it if necessary a few times to make the new pad and track more conductive, check that the track and pad are conductive. The new pad and track made of thin silver paint will be weak, but if you're careful you might get one soldering out of it without breaking it. As your new pad is made of silver you may want to use silver bearing solder to ensure a good joint.
I've given this advice on other forums and following it others have succefully repaired their equipment. But I can't make any guarantee's, it's just something I thought of that worked rather than a known repair techinique.Rubycon Rubycon Rubycon -

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.
First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected... -
Hi There,
This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.
After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt... -
Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.
Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
Power Board Connector that goes to Main board
CN6401
Pin 01 NC
Pin 02 NC
Pin 03 "BL_ON": 0V
Pin 04 "N/C"
Pin 05 "STBY 3.3V": 3.5V
Pin 06 "GND": N/C
Pin 07 "AC_OFF"...
