If you are having Problems with your TV, you came to the right place. I have many years of experience in working with all kinds of electronics equipment. The problem I mostly repair on flat panel TVs are :
Stuck on Samsung screen. Other makes too.
No power.
Power but no screen light.(Faint image on screen). Bad LEDs behind the screen can also cause dark screen.
HDMI ,or other ports not working.
Slow to turn on or takes a while to turn on (SAMSUNG TVs).
LCD screen looks messed up. (T-CON board).
In some cases I can repair the tabs on the Panel It will get you up and running better than buying a new panel(LCD Screen). This can happen with all makes and models of TVs. I use thermal pads to take more heat off the chips ,and to put a little more pressure on them to make the TV picture perfect. Please note if your TV Screen is damaged it must be replaced. This is the most expensive part of any flat panel TV. Your best option is to find another TV same model ,or one you know for sure that your parts are compatible with the TV with the good screen. I could also repair the LEDs behind the screen. There is also a video of me replacing the back light LEDs in 42 in LED TV.https://www.youtube.com/watch?v=vu_JsiXWKfI. These are some TVs repaired last month. Stay tune pictures of more of my works are coming. Thanks. A deposit of $30 is required before I start the work.
