Uploading good clear pictures of the boards and the whole back side of the TV so we can see how all the boards are connected together will be a great help for troubleshooting your TV.

Pictures is too out of focus to read the pin labels for the connector.

Can we get a closeup photo of the white 15-pin connector on the left side of the PSU board, next to the yellow capacitor? Need to see what the labeling is for those pins.

Apologize for the bad resolution of the picture.

I gonna try to send today a clear picture and also
For the 15 pin terminal.

Good day.
This is the clear copy picture psu board and

I found 2 diode supplying 5v was already. 1v
When I test in digital tester. But when you check
The standby voltage still giving 5vdc

Please report the DCV reading of each pin foe the connector CN803 when poweer switch is activated.
Please report in this format so it will be easy for us to see what are missing:
For example
13V = ??? V
13V = ???? V
12V(T-CON) = ??? V
....
.....
....

Re: Toshiba led tv 32P2305EE won't turn on

Pin 1 GND
2 13V audio= 13V
3 13V = 13V
4 12 T-CON = 12V
5 GND
6 5V = 5V
7 5V = 5V
8 GND
9 POWER_TV = 3.2V
10 DC_ON OFF= 3.2V
11 GND
13 EXTDIM = .4V
14 NC
15 NC

Re: Toshiba led tv 32P2305EE won't turn on

Pin 1 GND
2 13V audio= 13V
3 13V = 13V
4 12 T-CON = 12V
5 GND
6 5V = 5V
7 5V = 5V
8 GND
9 POWER_TV = 3.2V
10 DC_ON OFF= 3.2V
11 GND
13 EXTDIM = .4V
14 NC
15 NC

OK, so it has the correct Voltages and signals with an exception of the EXTDIM of only 0.4V. You may want to turn the TV off, then put the meter probe on this pin , then turn the TV on to see if the Voltage does jump up much higher than 0.4V and then goes down to 0.4V.
Did you see the LED backlights even flash on for second?
So far it looks like what you do not have are the backlights for you to see the images on the screen.

BTW, please stick to this thread so we do not have to follow the progress of the repair in two threads.

You've missed out pin 12? BL_ON

You've missed out pin 12? BL_ON

Ah, good catch!

[Nasha]

Re: Toshiba led tv 32P2305EE won't turn on

Pin 12 BL_ON OFF =0V

also I found out this diode who's series in pin
6&7 5V when I test in diode testing I get only .1v
Supose to we get is .3V to 8V correct me if I rong.

[Nasha]

Re: Toshiba led tv 32P2305EE won't turn on

.8V sorry

Re: Toshiba led tv 32P2305EE won't turn on

OK, the main board is not sending the signal to turn on the backlights circuits, and also the dimming command is also very low.
Your standby power supply is fine otherwise you will not have the PS-ON signal.
