Facing TV Problems? Ask a TV Technician.
Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
Which board are you referring to?Is there a solid or flashing light on front? Does it try to turn on but then shuts back off?
Do you need more help with this?If so, simply reply back on this page.
Please note: You have already paid your fee to the site; I'd like to help you and provide value for that fee, but I do need to communicate with you here to do so.
Fuses on these tvs rarely fail. If you are not getting even the standby light on, then you have a bad power board at a minimum, and that board would need to be replaced.

The fuse may be bad internally where you can't see it, meaning the filament may be broken inside the end cap. Did you test the fuse for continuity?If you bypass the fuse and jumper both sides of the fuse holder contacts, does it power on?
Thanks for confirming.That still points to the power board as the first failure point, proceed with replacing it.
Thanks for trying. Unfortunately, that is not the result we would expect - having no standby virtually always means the power board. It is possible this is from a bad main board, or that both were damaged together. So the next step would be the main board: http://bit.ly/1TdmMxy
Where did you get those boards at?
Thanks tom, sorry your last message didn't show up in my feed so I didn't see it until now.
If it is powering up, you're on the right track, but it sounds like you may have not got the proper match for the main, did you confirm it against your existing part number first?
