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.

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.SD TECH

I have a pth5498 when
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
My tv blinks 4 times
Yes - that is one of the possible symptoms. TV will shut down with no audio or video. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.
My picture was prodominately green/red. I took the
1.) It means the Glycol in the blue tube is bad--usually contaminated by bacteria--each of the 3 picture tubes has a sealed area between the face of the tube and the lens above.
2.) If you see a picture in Green and RED but blue looks like a floodlight--the blue tube would have to be removed, drained, and the area with the Glycol washed out---new glycol added and the tube resealed and installed back into the set.
3.) This is a fairly major repair--the Glycol is very toxic---like antifreeze but much more concentrated---unless you have done it before I would not suggest it as a do it yourself job.
4.) The bacteria never affects the RED(it does not seem to like that color) and only sometimes the Green.
5.) It may not be worth repairing as most shops charge 200-300 or more for this kind of repair---not to mention that after it is done quite a lot of adjustment to the convergence will be needed from removing and reinstalling the tube.
6.) I know I am not giving you good news but you actually found your problem yourself! If you need any advice or help reply to this post and I will try to assist you.
