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.

Short on the power and deflection boards---with set unplugged take a careful look inside for burnt or blackened parts etc.

If you unplug the set and look with the back cover removed you will find 3 large black round lens inside---light source (red,green,blue) for your picture--clean them with a lens cloth or a paper towel with glass cleaner sprayed on the towel.

Should be done about 1 time a year.

If model number is correct the akai is a samsung; from the rear with the cover removed are three rather large black lens (one for each picture tube) that point upwards.

If the set has not been serviced for a long time clean the lens with a lens cloth or a paper towel with glass cleaner sprayed on it.

These are the light source for your picture and if dusty the picture will be darker and dull looking.

The sound of it sounds like a power board transformer that went out on you, Looking up that part lands you about $95 bucks labor about $200 depending.

So its all up to you on where you want to take it.

I did also mention trying to sale it for parts to help you sustain for a newer set.

There could be many items that can cause that symptom. However I always assume convergence on any rear projection which can easily be checked by unplugging the convergence amp board and then plugging in the set and press power , if the set powers up turn it back off, and you will know the convergence ICs and associated resistors on that board have failed. Although its easier to replace the board unless you have good soldering skills. I am pasting a pic of the board which is suspended above the main chassis just mark the wires then unplug the set from the wall first, but then unplug the wires from that board and then try powering up the set.if you need further assistance , respond to this same post slinteriors_21.jpg
