Coppell TV Repair LLC offers you a set of replcement master/slave backlight inverters boards used in Sanyo DP42848 P42848-00 and other 42'' LCD TVs.

The boards you will receive are new OEM VIT71043.50 and VIT71043.51 or 100% OEM compatible ones.

Before placing an order PLEASE take your time to open the TV and confirm that those are the boards you have in your set!

Many TV manufacturers these days tend to change displays and backlight panels in the middle of their production process and as a result many times the same TV model may have slightly different internals - slightly, but differently enough to cause trouble if you assume what they are.

So before purchasing please open your TV and make sure it uses the same inverters as the one named and shown here.

Failure symptoms

A failed backlight inverter in Sanyo DP42848 can have the following manifestations in order of likelyhood based on our experience:

1) Show display for a few short seconds after powering on the TV, usually accompanied with a loud buzzing sound, then the display gets dark and the TV continues to work; if configured on the right input and supplied with signal the TV would produce normal sound

2) Sometimes the failure may come to a point - at once or over time - where the display will not get backlight even for a short while; it may come up dark from the beginning. Sound may still be or not be present.

3) In some not so common cases the inverters can fail and short in a way that would prevent the TV from coming up as the power supply board would detect the shortage and turn itself off. If you doubt this is the case the simplest way to verify it is to disconnect the backlight inverter boards supply from the power, which would eliminate the shortage. If the TV comes up and stays on (without backlight, of course) then this is likely the problem.

Boards will be shipped within one business day of placing an order.
