Thomson scenium 44

I do not know specific on this model (which youdid not give a model number)

The most possible cause is capacitors which fail but also other parts or software issues can be at fault. Sets like most modern types have a start up routine which verifies sections of you set are working correctly before fully powering up, so if a fault is found just shut down.
There may well be a known part or parts but sets are made with components fitted by passing through "ovens" to make solder joints, these are at higher temperatures than normal tin/lead and standard irons are mostly not able to melt it without damage to track etc.
My advice is to contact Thomson (French electronics giant) for their nearest service agent a far better solution than to try yourself, many of the "thin" sets after a couple of years (out of guarantee) are not fixable because they require panel changes which soon run out of stock if many go wrong, sad but true.

Hope this helps........

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.http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given.Surf the site with patience.

These blinks (flashes) are fault indication. By the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside the TV. Count the blinks occur at one time switch ON, carefully. Do it once again, and make sure about the number of blinks. If the flashes are continious, non-stop, the main system control IC should be suspected. If you wish to get more details, check the site linked here. It has blinking codes detail to many brand TVs.
