KDL-46EX523 Power Supply Board
Happy New Year!!
Woke up and started more troubleshooting on the Sony Bravia.
In a totally different post, I mentioned no power.Tested fuse soldered onto power supply board at the bottom right of
the picture and now its reading bad.Not sure how I missed it,but this is what I found.Are these pretty straightforward to
replace? Are these sold with the wire soldered on both ends?...Last edited by Global Safari; 01-01-2020, 10:39 AM. -

Re: KDL-46EX523 T-Con Board
Hello all,
Been awhile since I have been here, been spending time with the family.
Okay..so I am back troubleshooting this tv.Since I last wrote, I was having
a intermittent power issue with my wiring harness.Since then I ordered a new
one. I also bought a new main board before I had the wiring issue.With power
applied, I would see a red light coming from behind the main board.As of now
no red light at all.Checked dc voltage at pins coming from the power supply
not getting any 12 volt dc at all....Leave a comment:

Re: KDL-46EX523 T-Con Board
Found fuse on T-Con board...read fine.Took off each ribbon cable one by one
and no change.Like I mentioned in the previous post, the cable running from
the main board to the power supply has issues.I tested the 12 volts at the
test point on main board,but went down as soon as the main cable was
slightly touched.Have to replace that like now to really continue the
troubleshooting steps.Leave a comment:

Re: KDL-46EX523 T-Con Board
Hi,
That was my next step.Try powering it up taking one ribbon cable off at a
time.I get 5 blinks on my LED when trying to power it up.Code points to the
T-Con board.The power supply to main board cable has some issues also.
For some reason I have to position it just right just to start the trouble
shooting process.I will probably have to replace it. If taking one off and the problem
goes away, am I looking at a bad panel?Last edited by Global Safari; 12-23-2019, 06:34 PM.Leave a comment:

KDL-46EX523 T-Con Board
Troubleshooting my Sony Bravia KDL-46EX523.Curious if there are fuses on this T Con
board I can check? I have found that when I remove the LVDS cable from
the T-Con board, the 12 Volts test point on main board comes back.I have
replaced the LVDS cable with a new one. No luck trying to find a service manual....Last edited by Global Safari; 12-23-2019, 06:19 PM. -

Sanyo FW55D25F
Hello all,
About ready to tackle another project. Sanyo FW55D25F.
Friend of mine has it.Thinking about getting it from him.This is the picture
he gets on his screen. Looks like a LED issue.I know everytime you post a problem you need to post
voltages,boards etc.Just by looking at this picture,I just wanted to get some
opinions from the group....Last edited by Global Safari; 12-16-2019, 05:09 PM. -

Re: Sony KDL-46ex520
I just did a continuity test on the 3 fuses.All tested fine except F6001. Read bad. This is the culprit. Can it be replaced ( looks very small) or is this a whole board replacement.Last edited by Global Safari; 12-02-2019, 06:26 PM.Leave a comment:
