OK, I will download them and see if they are good enough for tracing out the circuits or not. In the meantime we will wait to see what kind of Voltages you have on those connectors.

full pic of the back of the power supply board (flipped over the vertical axis) plus close ups of the 4 quadrants of the board starting from the top left and going clock-wise.

I need good clear straight shot pictures of the bottom side of the power supply board to be able to figure out what those two resistors are for.

Re: Sony NSX-32GT1, Power Surge, No video/audio/lights, just a clicking sound

^^ the two resistors I was talking about in my first post are towards the upper-left of the white sticker/transformers close to the bottom of the second pic (the one of the power supply board). not sure if they're actually important or not though...

Re: Sony NSX-32GT1, Power Surge, No video/audio/lights, just a clicking sound

p/n is 4-193-998-01

I left my multi meter at work today but I'll bring it home tomorrow and get some more readings then.

leaving some pics for now

We need good clear straight shot pictures of the bottom side of the board so we can trace out the circuit in that section where the two resistors are.
BTW what is the full p/n as printed on the white sticker?
4-193-998-????

Need voltages from connector that goes from power supply board to main board. Will need pin#- PIN DESCRIPTION -Pin voltage in standby-Pin voltage when pushing power button and picture of connector on power supply board.
Format:
Pin# - Pin Description - Pin Voltage standby - Pin voltage power on
1 - XXXXXXX - XXv - XXXv
2 - XXXXXXX - XXXv - XXXv
3 - XXXXXXX - XXXv - XXXv
4 - etc.

^^ To clarify, the resistors are on the power supply board and look like this:

Re: Sony NSX-32GT1, Power Surge, No video/audio/lights, just a clicking sound

Hello.
I have the same TV, and am having a similar problem with the TV staying on (NSX-32GT1). I plug in power, and the LED turns red as normal (one loud click). When I try to turn it on, however, it tries to stay on for a few seconds, then turns off and the red LED blinks 5 times, pauses for a few seconds, and repeats blinking 5 times.


I just brought a multimeter home from work today and started taking some volt readings, but before I got too far, I just tried turning it on again and it's working now.

A few days ago, I was able to get it working after a few powercycles, but then it stopped working. Obviously, there is some part that is dying, but I'm not sure what. I measured 120VAC out of the power supply. One weird thing I noticed was R6501 and R6513 were running inconsistent voltages. With the power cable plugged in but the TV not on, they would fluctuate a few dozen volts relatively quickly. I'm not sure what the purpose of these resistors are but it seemed strange to me. I was measuring DC, as AC just showed up as 0V.

Any ideas on what might be happening?
Thanks.

Sony NSX-32GT1, Power Surge, No video/audio/lights come on

I have the same TV and had a very similar (scary) lightning hit near the house. All my A/V equipment was on a surge protector and all was good there. The TV was plugged directly into the coax cable and it was the closest TV to the underground cable coming into the house near the tree that got hit. The TV went out and NO power light comes on, clicking or any sign of blown fuse.

Would this indicate the BA board that the cable was plugged into is blown? How do I test that? First time user....Thanks!!!

I'm happy to report that the TV is now working. I bought a power supply board from Tri State Module for about $55. I swapped it out today and no more clicking. The TV now powers on properly. It's got a total of 4 HDMI inputs. One of them does not work. I'm not sure if it is the one that was plugged in at the time of the surge but it most likely was. When I turn on my LG Bluray player connected to this bad input it will initially show the LG logo and the red warm up dots along the bottom of the screen but after that it doesn't show anything. So it's probably something simple on the main board.

So going from nothing to 3 out of 4 HDMI's working for just $55 I'll call the job complete and consider it a success.

I greatly appreciate the help that people provided!!

i got this tv 40 inch model

I like this model. It's pretty nice.

Thanks for all the help Martino. I should be able to post an update within the next 2 days.

Ok,now it's time to get the multi meter out.
We will be most interested in standby voltage and ps-on for now.
A lightning strike like that often takes out the inputs on a mainboard. Then again a power supply could easily fail with a surge like this. Hence the unplug those connectors and see if clicking is still there. Starting to look like mainboard but we should make sure power supply is ok too. You said a friend has a meter you could borrow?

Re: Sony NSX-32GT1, Power Surge, No video/audio/lights, just a clicking sound

I gave it a try. The CN6150 goes to the main board (BA board) and the small plug beside of it goes to the M Board.

I tried unplugging it in stages. I first unplugged both connectors and no clicking sound when I plugged the power cord in. I then plugged in the M board and still no clicking sound. I then plugged in the main board and the clicking resumed. Ouch! Does that mean it's more likely to be an issue with the main board rather than power supply?

I kind of jumped the gun and ordered the power supply board from Tri State Module for about $55 along with another part for a different TV. Worst case would be I'm out about $11 for a restock fee plus shipping if I have to send the power board back. Plus, the main board will be a bit more expensive (be lucky to find one for $100).

unplug tv,unplug connector cn6150 and the little guy beside it....plug tv back in,still clicking?

[jimbo71]

Re: Sony NSX-32GT1, Power Surge, No video/audio/lights, just a clicking sound

It starts clicking as soon as you plug in the power cord.

Re: Sony NSX-32GT1, Power Surge, No video/audio/lights, just a clicking sound

Does the tv start its clicking as soon as you plug it in,or when you press the power button?

[jimbo71]

Re: Sony NSX-32GT1, Power Surge, No video/audio/lights, just a clicking sound

Below is a link that shows a closeup of that connector. I don't have a multi meter (or know how to use it) but a friend might be able to help me this weekend
