Have TV Questions? Ask a TV Technician
Hello, my name is Rusty. Is the power cord for the TV plugged in? Does it have a box in the middle of the power cord? Is that firmly connected at the box?
Hello, My name is ***** ***** this is a different expert here. Rusty had to leave to work another job. This set doesn't use an external power box as previously mentioned, it has an internal power supply. That said- can you please tell me if there are ANY signs of life at all on the TV (power light lit or blinking, click sounds when power is pressed, etc.)?
Let me know if you need assistance with this.
If there are absolutely no signs of life on the set at all as requested above, then this indicates the set's internal power supply board has failed and requires replacement. This is very common with flat screens as the power supply is a digital switch-mode board that is built much lighter than a conventional power supply. To fix this issue the power supply board would need to be replaced- which is a plug and play component (meaning no soldering or special tools are needed to replace it) .
If you're looking to perform a DIY repair, you will need to remove the back of the set and visually identify which model power board your set uses. There are two listed as working in your model number- but you still need to match it up with the one that you have. This board is available for right around $35 at the link below for your set:
Alternatively if this is not something you're comfortable with, then a shop will typically charge $150 parts and labor for this repair- which is generally not cost effective since the TV can be replaced for the same cost. However if you would like to inquire about repairs, or seek a 2nd opinion you can use the link below to locate a shop in yuor area:
Other than that, I'm sorry for the bad news and wish there were a quick fix.
