Re: insignia NS-40D40SNA14 power issue
F to G is open circuit. The solder looks good on each legs. Should I try to resold it or just change the EMI filter, DG-168-CV? Can you help me with the specs for this?

Re: insignia NS-40D40SNA14 power issue
Sorry, the bridge rectifier has 0.02V on the AC side. I checked the voltage after the fuse before.
Can be the yelow cap, .47K275V-X2, the problem? I have 0.02V on its legs.

insignia NS-40D40SNA14 power issue
Hello to all
I had a 40'' LED TV NS-40D40SNA14 with no power.
The main fuse is good. I checked the main capacitor, 64uF 400V, and found 3.4V which is not correct. It seems to me to have a problem in AC side, but the caps looks good. Can somebody help me here?
Thanks... -

In this situation I quit. The power supply is more expensive than I expectedand it might not solve the probleme.
Thank you very much for your help.
Happy New Year!!!Leave a comment:

Re: Toshiba 58L135UC Power issues
It works perfect. Do you think the power supply can generate this problem too?Leave a comment:

Re: Toshiba 58L135UC Power issues
One of my neigbors gave me this Tv. He tried to opened it first to check the fuse. I don't have the remote.
When I saw the Tv, it had the front power button weakened. Is there a way to check if it works?Leave a comment:

Re: Toshiba 58L135UC Power issues
I was wrong... I tested it again, it is OK, it gives 0.273V one way and OL on the other. What should I check now?Leave a comment:

Re: Toshiba 58L135UC Power issues
Outer pins comes from T1 and they are not connected together. That is like we have two diodes, right? These are the 12V otlet from T1? Do I have to remove D201 from the board to test it?

Re: Toshiba 58L135UC Power issues
J26 -- 1.68V
D401A/B are ok
How could I test D201?...Leave a comment:

Re: Toshiba 58L135UC Power issues
I read the same voltage before and after pushing the power button
3 - 18.35v
2 - 14.79v
1 - 14.11v
That means we have 14V to VCC pin on U1 and it doesn't goes thrue U1, right? Can I test the U1? Could be a problem on the power swich circuit too?
