The fuse may have blown due to this:
"2- I connected the flex back,this time TV was still ON. The screen turned white entirely"

good spot budm i missed that completly! i would try a new fuse and see how you get on.

Ok, thanks, so the fuse might be another problem on top of what may have caused the lines... I'll get the fuse and report back ASAP.

Hello friends, I was wondering about how to shop for the correct SMD fuse. I can read it has an "L" or a symbol like a straight angle with a small "F" inside(over the foot of the "L") followed by "3A".

That symbol LF stands for Littlefuse company. You have to measure the width and length in millimeter to find the correct size for this 3A fuse. I myself use PICO II axial lead fuse, just have to bend the legs to fit, no need to remove the old fuse. You can use 3A car fuse or any other type of fuse with legs for quick test for now.

Hi everyone, I just want to beg for your patience, I'm having some issues with my car and need to fix them before going to the nearest Shack and see if they got something to help me here. Just to clarify, can I use one of those glass tube fuses as well as any car fuse?

Re: Sony KDL32L5000 screen stays black but audio works fine

Yes, as long as it is 3 Amp just for testing right now.

I have just found 250V 3Amps fuses, is it OK to use any rating for voltage? I think the voltage in the T-CON is around 12V or maybe less.

Re: Sony KDL32L5000 screen stays black but audio works fine

24V is the minimum (12V x 2) in this case, so 250V rating fuse is OK.

Hello everyone, I got fast-acting, 250V / 3Amps fuses. The dimensions are .5x20mm. The next step should be to solder a lead to each side and then solder the opposite of each lead to the corresponding end cap of the defective fuse, right? Or do I need to remove the old, blown fuse?

Re: Sony KDL32L5000 screen stays black but audio works fine

yes for now just solder to each end of the old fuse this is only for a test to make sure nothing else has blown etc.

Hi every one, thanks for your patience, I've been having issues with the ISP and their service is crap as for the last month. Anyways, back to the TV, I soldered the fuse and the TV turned on, the horizontal,grey lines on top of screen are gone and seem to have been a poor connection of the flex cable, in the other hand, the vertical green lines persist. I can post a picture if you would like to take a look at it.What's the next step? Thanks again

Re: Sony KDL32L5000 screen stays black but audio works fine

Here are the pictures, notice that the vertical green lines are visible after a few seconds of powering on, then they get brighter and even a Red or Orange line can be seen beside the first GREEN one after a few more seconds.
