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/
U have tools like a soldering Iron and roll of solders?Can u also do basic soldering works?Yes take the tv aparts and resolders the FBT-(flyback transformer) that the big block of plastic with a red wire with a black cap hook up to the tv CRT-(tv tube).Also the tv video board that the board that hook up to the tv CRT-(tv tube) tube neck hook on to this video board.Resolders that board too.70-80% will get the tv working again.
If the lamp has been replaced I would think the Lamp ballast would be most likliest followed by the color wheel and then the Digital board. You can get any part needed for your model at www.tvrepairworld.com just leave them a email they respond quickly.
I have a similar problem with Thomson 52JW643 S in that it takes at least 12 to 16 attempts before it eventually turns on very very annoying !!!!!!! turns from red to yellow to green then back to red and then same again until she feels like switching on then perfect picture sound and quality ??????? can any one advise please
Your problem is in the switch mode power supply or the horizontal out circut.
sometimes the small CHOKE that feeds the base of the horz. out transistor has a cold solder joint.
resolder both ends first.
Thanks Guy9
