@pug-man, what answer you expect to hear?
- "Unscrew that screw, pull out that board, replace elements A, B, C"? Can you replace SMD elements?
- "Replace the PCB trace from point X to points Y Z if damaged"? Can you fix 0.5mm PCB board?
- "Measure the current thru element P and if below 1ma, replace element Q"? Do you have a multimeter capable of such a measurement?
- "Check the waveforms at TP7, and compare to reference". Do you have 100MHz osciloscope?
- There are quite harmfull voltages lurking inside that TV. Do you know where they are as to avoid them? Do you know how to deal with them?
First of all, did any of these questions make sense to you?
Second - you will not get these kind of answers. If you have no electronic experience (as it seems is the case), then you have no other option but to give it to a professional. And these professionals have spend couple of years studying and practicing their skills, so their services are not cheap.
I hope you will be alive to tell your firstborn that story about how you fixed your TV.
