That kind of capacitor will not show correct ESR when using ESR meter.
Your multi meter does not have capacitance meter.

Okay I'm going to get a better DMM that can measure capacitance

Hey Budm,

I got a DMM but it's giving out 0 capacitance if I'm testing it correctly? I've attached a picture of the DMM. To test it says to put it onto uf setting and to insert into test holes on the top right and not to use the test probes. Is this correct? Tried it on all the uf settings and it's still 0.

OK, the suspect cap is 0.018uF (18nF), so you need to set your meter to 20nF and see what you read, then try it again with 2uF scale.
So did you remove the cap to test? you can use the test probes for this size cap, just do not touch the probe tips with your hands.

Had the red test lead in the wrong socket before.

At 20nf it fluctuates from 17.66 to 17.70.
At 2uf it's .018
Yes I tested it out of circuit.

OK, it is good, more in-depth troubleshooting in that section needed.

Re: Sony KDL-46W4000 (2 blink code)

Thank you for your replies.

Are you able to help further sometime or is that as far as you can go with me? Its okay if you can't.

Re: Sony KDL-46W4000 (2 blink code)

I will have to study the circuit more to get further.

Re: Sony KDL-46W4000 (2 blink code)

Hi Budm,

Are you able to still help? I left it this long as I didn't want to bother you.

If it's too much to try help on here further then it's probably better to just sell off the TV to someone else.



Thanks

Don't leave it so long We are more than willing to help people out, though if you leave a thread dead for some time we forget about it as we tend to a lot of threads. Keep the thread alive by looking on google and here for ways to test components... EG Mosfets etc... Test them and post results of them if you think they are in the section that could possibly be faulty... Even if its not and you have tested them wrong it keeps the thread alive and also gives you some experience and knowledge as we will tell you if its tested wrong, reads wrong etc

So you learn and we keep seeing the thread.. Win Win

Sorry, the post did not pop up until something new is posted.
The only thing I can think off is the the IC 6100 CXD9841P for that 12V SMPS section, the MOSFETS are not shorted out, the PFC Voltage is fine, the fusible feeding the B+ to the circuit is fine, the output coupling cap is fine, the VCC to the IC is fine.
