I have a emerson blc320em9a doesnt come on and no power light on when plugged in. What do you think it might be. Main power board looks good and fuse on board is ok.

a blown fuse is a dead short of the circuit
it could be a failed power board , control board , megatron, light wire anything powered by the fuse
good advice is to take it in for a proper diagnosis and quote

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

I think your model number is actually LSC26905SB
There isn't a fuse panel, per se. If I remember your model correctly, the main board is on the back, so pull your refrigerator out, unplug it, and take off the access cover located about halfway up your refrigerator's back. Look at the fuses on the main board. There is a 20 amp fuse that blows easily (the newer boards have a slower blowing fuse in them, now). Temporarily jumper the 20 amp fuse and then plug your refrigerator back in. If you hear relays clicking and such, that's good. The compressor should start up shortly afterwards and all the lights should be on in your refrigerator.

After you have verified operation, go to Radio Shack, or somewhere similar and get yourself a 20 amp slo-blo (slow blowing) fuse and solder it on top of the old fuse on your main board.

Remember to always unplug your refrigerator when dealing with the main board and power circuits.

Good luck and let me know if you need any more help.

Check and replace damaged component/s at it main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Surf the site with patience. Pull up older posts. Do a search by type in the brand name of your device at its search box.

It will be best to replace the power supply regulator board as card basis.

That can be a common location for problem capacitors. and certainly worth a check.

The simples way to go about that is to unplug it, wait 30 seconds and then plug it back.

if it doesn't come on then it has a problem, which may be with the power board or the main board.

I have seen this particular TV with bad main board and bad power board (in fact it has two power boards) and unfortunately I can't suggest which one is more likely to have happened.

Sorry...this one will be calling for a tech to look at it.

Don't kill the messenger :-)

blows the fuse next to the power cord everytime you plug it in. can you help

There is a fuse on the power supply close to where the A/C is connected to the board. If the fuse is blown, look at the board and see if there are any burned components and or swollen capacitors. If there are bad components, I would suggest getting a new board.
If the board looks OK, disconnect the connectors from the board but leave in the A/C connector (this way you can isolate the power supply board), replace the fuse, and power up the TV.
If the fuse pops after the power is applied to the unit, then the power supply is bad.
If the fuse is still good, then power off the TV, connect on the main board’s connections, and power up the TV.
If the fuse is still good, then power off the TV, connect the inverters, and power up the TV.
If the fuse blows now, then the inverters and or the panel are bad.
A working power supply will create 5vdc for the main board’s stand by source voltage. This can be found on the power supply at the main board’s connector and it is labeled in black text.
I hope this information helps you.
Good Luck.

Have 1 of 2 choices, the main fuse or the control board for the front switches and clock. primary of the small power transformer has opened. Unplug the unit and take case off and measure the fuse with an ohm meter. if u read 1 ohm or less then fuse is good. then measure across the main power plug tips. If read open then the power transformer is bad. Need to replace the board as not sure if transformer is available.
