Phillips 40PFL3705d/F7 image issues
Hi,
I picked this 40" lcd out of the garabage a few weeks ago. I plugged it in, the backlight light up fine. The sound and tuner also worked when I connected a DVD player. The picture did not work. The 3.15 amp SM fuse was blown on the T-Con board. I momentarily jumpered the fuse and the screen came to life. I replaced the fuse and 8 electrolytic caps on the T-Con board. After the repairs I ended up with all the TV's functions working except for the onscreen image. The image I get is not correct. I have tried setting in service mode but they don't help. Does anyone have an idea of what is wrong? Thanks, Ed

I would say with a blown T-con board fuse, that the there may have been some other component damage done, like the ASIC's on it. Perhaps look for a used T-con board for the right price? Did the set look like someone else had been "in there" (signs of cam'd out phillips head screws/etc)?

I know I used to work on a lot of philips/magnavox tvs, and if I put a mainboard in a tv with a different panel type, it would look like that. I'd go into the service menu and change the panel type and it would clear up.
Now, I don't know your set would have magically changed unless somebody else screwed around with it first... Or it could be something else entirely. I just saw that screen and "wrong panel type" popped into my head...

match the the service menu listing. It's worth a look.
