Facing TV Problems? Ask a TV Technician.
Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.
Initially, is the TV completely / electrically dead? ...or is there some indication of power such as a stanby light and only that it would not fully power up?
Sorry to hear of this.
Are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter and even perhaps a soldering iron?
A completely dead TC-L42E3 would be indicative of an internal hardware issue.
Are you then considering blind replacement of the most likely faulty board?
This is a 2011 model. Most of the parts would still be readily available and reasonably priced.
In most instances, it would be the service fee that would be a major concern.
Please post back how you would want to approach this and/or should additional information be needed.
Thank you for allowing me time to compose my reply.

The described symptom of "...Does not power on..." could be as simple as a blown fuse.
...or the whole power supply board has failed. The Part Number is ***** subject to verification as depending on the version and revisions.
Posting a potential online parts source was to give you an idea of the cost of a replacement board.
Hence if a repair person would come for an on site repair, you would have an idea of the parts cost.
Or even when just quoting for the repair charge over the phone.

Comparing the quote and the cost of new, an informed decision can then be made.
