    Ok. I have not been able to locate the exact part no, but I could find a similar part that is the auido/video board. Does the part you have replaced have all the inputs and stuff on the back of it?

    Ok. I got it. From what you have described, the power board was not the only thing damaged . Main board is as well. It is very much possible as I have seen this happen several times due to power surges. I am positive that replacing the main board will resolve the issue

    I have both. Compare the part number with that of the mainboard in your tv. You can find the part number on a small label on the board. As you have seen there are several Rev(revisions ) of the part, and I want to make damn sure that you get the right one.

I have a proscan 42" LCD TV, model number 42LA45H, and the TV kept shutting off after a few seconds, now it just doesn't come on at allThe red power light is on, but that's it. Can you help me please?


Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
