Yes I did. I got a Vizio E 55 – you won. I ordered the repair kit from you and put it in and then I had lines I didn’t have no picture so I put my old PC board back in and I had picture and it was doing good but the right side would flash this weekend I went Pulled the screen out and went to do the LEDs and noticed that that one side was flashing all the lights so I put my old PC board back in and the light stop but then I had lines I’ve been trying to figure out which where I went wrong because I put the old one and I got I got it. I got a TV but the right side flashes I put the board I got from you guys in and I get lines and messing with tonight. My burned out my power board, so give me some help. I don’t wanna return them because I the power board or the PC board. I I don’t know. I don’t know if you gave me the wrong one or shorted out, I don’t know But it was working fine outside of the flashing on the right side, then put the other one in and it stopped flashing so then I put the TV back together and headlines and then I was trying to trace down. I didn’t have no picture just lines and somewhere along the line of burned out the power board and the TV was already burned up.

Hi,
I recently changed the backlight of my Samsung UA50KU7000 4k Led, after replacement I first facethe issue of yellow tint screen which was quite settled by RGB adjustment, then I face the issue of dark colors, my Led was perfectly displaying before the backlight replacement, though I installed the backlights according to the model number but yet I lost the perfection of image.
I have a doubt about Tcon connections, the ribbon cable, the technician didn't paste the sticking tape on the ribbon cable along the metal body.
Any suggestion what causing this problem ?

Hello! I have a Vizio M50Q6-J01, s/n LTCUG6LX2854238. It has developed thin static horizontal lines, several near the middle, and some near the top 1/4 of the screen. They are mainly visible when the screen is red or has reddish images. They do not flicker or move position. I'm handy and not afraid to do repairs, so any suggestions or help you can give would be appreciated. Thanks!

I have an element e4aa70r tv that just stopped working. The light on the power button blinks but it doesn’t turn on. I’ve tried resetting it a few different ways and nothing has worked so I’m guessing it’s a hardware issue…?

I have a 2020 Samsung QN58Q60TAFXZA

I’ve checked power supply cable, swapped with one from a working Samsung TV and tried different outlet.

When you press power on the red light goes solid for a second then blinks. The TV looks like the backlight is trying to turn on then it goes black. It just keeps repeating itself until you unplug the power supply again.

I’ve been reading and watching videos and I cannot find anything that describes the exact symptoms I am getting and my 3 year extended warranty expired 2 weeks ago. Any advice would be appreciated.

Panasonic TX-55CX400B, hey I have a problem where sound will play but the screen goes black, woundering if this is a T-Con board issue as it seems the backloght turns off aswell, tried putting a flashlight to the screen but no image comes through which I believe means it is not a backlight issue? Any help would be great as I want to buy replacement parts and fit them myself

I have a LG 55uh6030. I started getting vertical lines so I ordered a replacement T.-con board from you guys. After replacing it everything worked great! However, recently when watching it, seems like when it gets warmed up it gets vertical lines on the right side of the screen then screen goes black and no picture at all. If I turn it off and allow it to cool down it would work fine again. Until it happens again. Please help 😢

I have a Sony bravia XBR-55X950H, SERIAL NUMBER 4012137. Its way out of the one year warranty. I have thin horizontal black lines that appear for 5 seconds then disappear for 5 seconds and the cycle repeats and repeats. The display dims when horizontal lines show up. The lines are more on the left side than righ- but most of the way across.. It has nothing to do with the incoming signal nor anything attached. Sony people say it needs "official" Sony repair. I have the back off... no simple task and I think it might be the T-con board. What do you think? Alan

The logo appears for 1 seconds then the screen goes black on OLED lexuco tv. What’s the issue
