Vizio XVT3D554SV, XVT3D474SV and XVT3D424SV repair offered

With a few years delay we're updating customers and Internet in general that Coppell TV Repair LLC is offering repair services for the main boards for the XVT3D series from Vizio, namely:

• Vizio XVT3D554SV main board repair service
• Vizio XVT3D474SV main board repair service
• Vizio XVT3D424SV main board repair service

As with  (almost) everything else, we test those boards both on the way in and the way out of the shop as can be seen here:

We also have replacement EEPROMs for those main boards, which you can find at www.coppelltvrepair.com.

Every now and then we also have boards available for purchase with trade-in option for the old dud (CORE purchase), but customers frequently either do not return their boards or return them so badly damaged they either can't be repaired or can't be sold or warrantied because of the way they look....and that unfortunately ends up the sale-repair-sale cycle until anther board becomes available.

Samsung UN50H6203AF no image issue troubleshooting

In the past month we've seen a few units of Samsung UN50H6203AF in the shop with the same issue - TV starts up, backlight is there, but there's no image on the screen even though the T-CON LEDs are on in blue and it appears as if the T-CON is just fine.

Testing output voltage to the LCD panel shows that at first it gets a spike of proper voltage, but then goes down to 0.

Then we actually ended up "repairing" (though frankly I still don't dare call this repair) one of them with another one currently waiting. The "repair" is something we've done before as a last resort by means of losing portion of the panel and re-purposing the TV for digital advertising or other situation where one could go with missing an inch or so of the display.
