Those 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 have an Emerson tv 32in model no. Lf320em4a it’s about 3yrs old it won’t turn on the screen starts and shows the Emerson name then shuts off.is there a fuse or etc or is it just shot


Check your voltages when you power it on compared to when it shuts down...see what rail is dropping off for starters, then I can give you more of an idea where the issues are at..I have a feeling you have inverter issues because this was a common failure on this set check and see what voltages drop off after the startup screen

Hi I have a Emerson lf461em4 when I turn it in Emerson comes across the screen and then the screen goes black

Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electro-medical.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

I replaced the main board on a Emerson model LF320EM4A TV & still no picture ? There is only one board and tv repair man said it needed to be replaced. Still no picture?????


Put a flashlight to it and see if there is a picture. If so the back light has gone out. If not then the lcd must be out if there aren't any other boards.

My emerson tv keeps turning its self off after a few seconds


I do not have a model number to go with. But I would imagine this TV is still on the new side. If this is the case, the values on the starting resistors for the inverter board have changed values. You will need an inverter board replaced. Or if you know of an authorized Philips Center, they may replace the resistors with the same value or new values, depending on the model number of your TV. Thanks for asking and show a few hands of support!
