Re: Benq 17" Q7T3 fix
I have read elsewhere on the Internet that another theory about the transistor blowing is that the joints on the HV transformers are cold which causes the transistor to come to an early demise.
Other sites are simply saying remove the old solder on the transformers and resolder the joints and you're all set.
Does this sound possible or is it just crap?
I do agree that at least on my board the solder joints are all crap. Yesterday I gently bent back a transistor (like I've done many times before) to read its number and before I could even get a little pressure on it snap the solder joints just cracked.
So I don't dispute the fact that the solder joints are below average.
I attached a picture of my inverter board to this post its manufactured by Benq 48.L1A02.A00. I'm just curious if it looks familiar.
Also if you look at the picture the board is a little darker around the HV transformers I hope thats normal and doesn't mean that the HV transformer got cooked.
FYI I took this pic before I started recapping I will be getting rid of all those Elite and Lelon Crapacitors very soon.
