This repair kit addresses a common failure in power supply board AOYUAN AYL400201 / AYL400202 used in PROSCAN 40LD45Q and possibly other LCD TVs.
Please read the listing carefully and in full to avoid possible confusion.
Before placing an order please ensure that the board in your TV is the same as the one in this listing! It is common for manufacturers to make significant modifications in TV contents without maing changes to the packaged model.
Coppell TV Repair will not be responsible for orders placed by mistake!
The most common failure symptom and the one tha this kit cures is usually manifested by the TV coming on for a few seconds and then shutting itself off.
Over time this can get to not ever showing backlight and directly shutting off.
Unfortunately the same symptoms can be observed from other failures, so we can not guarantee you that this kit will resolve the problem based on symptoms alone.
Visual inspection of the small blue capacitor C26 located on the outer side of one of the two large high voltage transformers may sometimes reveal swelling or even burning, but this is also not always the case.
Measurements with DMM are not guaranteed to help either as the problem may only show itself under load conditions (high voltage and high frequency).
This is as easy a repair service as they come, but it still requires some basic soldering skills.
You will need an iron - almost any will do, some solder and a Philips screw driver so you can get to the board.
