47pfl6008 blinking red

[domix]

Hello,

i have 47pfl6008, at latest half a year sometimes TV turns OFF suddenly. Then you need to turn ON again. Yesterday when i want to turn it ON, red light blink two times than pause, and again two times in a sequence. I plug it out and then back in. Now the red light is off and TV wont turn on, only a short red blink for 0,1sec.

What to check, seems everything oken on MB.

Which is the Country S??
Very common problem of the model, bad BGA solderings on the main chip (Fusion).. Reballing is a solution, reflow is a looser solution..

I dont have option for reballing, i can reflow with hotair or i put it in oven :P

What you don't understand that is not the heat the problem, is bad solder, soon or later you will face against the same problem, if i have time i want to experiment on mine, these days of weekend, i have two of those sets sleeping since years.. i want to warn you that years ago i tried reflow too but a previously half working set became totally dead, no components flawn..

I heat it wit hot air gun pn 150C at the back side of the main chip, than carefuly put it in oven preheated on 180C for 40 seconds. Now work just perfect, everything is fine

So see you next when you'll come here with same problems.. and good appetite with poisoned foods.. bye..
