Generally it means set is not making it from standby to on.

Problem could be in power supply or elsewhere.

A brand and model number might shed light on what to look for here.

You either have broken power board or main board. Power board - blinking 2 per second, main board 3 times per second. In an case it has to be fixed by a technician.

Blue light keeps flashing and willnot swicth on

What is the brand name to this TV? Provide more details please. These flashes are fault indications. From the number of flashes occur at one time switch ON, you can get an idea about the faulty circuit stage inside the TV. If you wish to get more, check the site linked here. Blinking codes [these blinks are called so], to different brand and model TVs are give in detail You can get an idea from it, provided you're somewhat sound in electronics. Pull up previous posts, either by type in the Brand name to your set in its search box, or view it in Mosaic / Timeslide / Flipcard option. Select view option by the drop-down view box, at the top left or the display window.

Samsung le32r74bd flashing stby chked psu all voltages ok but crowbarring down,found control board 05a30.1a to be the cause ,replaced contr pcb ,now powers up ,backlight on ,all volt present But no sound...

Hello there,
The problem with the television simply is that the lamp is bad and need to be replaced. When you were having the flashing standby light, it was simply indicating that there is a problem inside the unit. The problem could be from anywhere inside the unit.
Since you have checked the power board and saw that it was okay, it is qiute clear that the problem is not from the power board as it was powering up but the main board was not using up the power that is why the power light was flashing.
The solution to this problem is for you to check the main board and other boards in the television for bad capacitors. Have them replaced once they are found and then check the lamp of the television. That also should be replaced and the teleivision should be in good shape once again.
Hope this was helpful to you. Goodluck Elect_Comp

Hi, My teleivision will turn on briefly and then appears to be shut down and the blue indicator light starts flashing. I've looked for a reset switch and their doesn't appear to be one., I was wondering if...

Take the back off and Look for the PSB-Power supply board in the center of set. Look for 2 Blown UF capacitors on the PSB. A bas cap will be bulged or split at the top (X). Recaping is failry cheap. Under 20 bucks if you DIY.

Blue power light keeps flashing, but the tv won't turn on

Same thing just happened to mine. I think these replacement lamps (L2114A) are nearly impossible to find. They are no longer available through HP and I've ben unable to locate one through a reseller.

The tv willnot power up .the light keeps flashing and huming

Check the horizontal output transistor (H.O.T.) next to the flyback transformer. If it is shorted, the switching supply won't turn on.
