TV turns on but powers off after approximately 1 minute. Any suggestions?


Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Does apower supply cost the same as a main board for a samsung TV


never!
power supplies are the lesser of the two evils- usually, depending on model, the power supply costs is approximately $100- 180.

if you have a Samsung that just clicks, a relay clicking sound on and off on and off...it is a simple repair that can be done for less than $20 if you can work a screw driver and have a soldering iron.

Turning on the Power


Your power supply board needs to be REPAIRED not REPLACED, replacing the board will just make the problem happen again in two years or less, if you can use a screwdriver you can send me the board and I will repair it for less than it would cost you to do it yourself ($50) with the correct components.

I don't have any power to the t.v. even though it's pluged in to the outlet. It's a emerson model EWL20S5B?


Small TVs like this almost always are made up of two boards inside - a power board and a main TV board.

And almost always there's a fuse on the power board, near where the power cord goes in.

Checking that fuse is the only thing you can do by yourself.

Your next option is to give the TV in for repair to someone who fixes such things. Chances are high the problem is in the power supply board and is repairable.

However, the cost for doing so can be prohibitedly high as cost of the TV itself is prohibitedly low. I mean you may be better off selling it on eBay for $50 and buying a new one.

I know I'd buy it for $50 there.

Protron 42" tv


I would suggest to search for customers reviews of this product if you can google it. Personally I have not own one of this TV, I only service them.
I think LCD's and Plasmas are newer technology and the designers and manufacturers still trying to make them better. If you buy one of this TV, try buying the extended warranty if possible.
In regards to the power supply repairs, It could go from about $85.00 to $125.00 or it could be more expensive if you're buying a new board.
