Re: 32" Dynex DXL3210A Won't Power On
I have the same model and it does a very similar thing. Yellow standby light--> turn on and it turns Blue ---> TV turns on for 2 minutes then turns off and speakers make a popping sound. BUT the light is still blue. If I click to turn off the light goes back to the yellow standby and I can repeat the same process over and over. Any ideas?

Re: 39L22U Toshiba LED TV
I've looked everywhere for a schematic to no avail.. This will be my last toshiba TV. Thank you for your time!! Have a great night. By no means am I finished working on this TV

Re: 39L22U Toshiba LED TV
I agree with you 100%. Crossing the PSU w 1k jumpers enables it to function properly. So my guess it may be a component on the main board.Last edited by Gonnafix; 09-03-2015, 10:19 PM.Leave a comment:

Re: 39L22U Toshiba LED TV
I just pulled the DIM cable from the socket going to main board and jumped w 1k ohm resistor back to PSU 5v connection. Still nothing. Do the other two 1k's have to be connected as well?Last edited by Gonnafix; 09-03-2015, 09:58 PM.Leave a comment:

Re: 39L22U Toshiba LED TV
Nothing happens.. I'll try and trace that circuit. Thanks!Leave a comment:

Re: 39L22U Toshiba LED TV
Connected BLON, backlight stays on now.. 11.9v on 12v ports. So it looks like it's switching on..Last edited by Gonnafix; 09-03-2015, 07:28 PM.Leave a comment:

Re: 39L22U Toshiba LED TV
I don't want to waste your time so I'll say here I am a bit confused.
You're asking for:
1K between 5V and the DIM and 1K between PWON to 5V for forced power on?
ACD is 5V
Do I connect BLON to 5v as well?
I completely appreciate your time here, my apologies if I'm not catching on w this.
Thank you!Leave a comment:

Will retest now.... Thx!Leave a comment:

Re: 39L22U Toshiba LED TV
Any thoughts on what could be preventing voltage to the DIM port? Nothing on it looks bad.. I guess I'll trace the circuit and begin testing individual components.Leave a comment:

Re: 39L22U Toshiba LED TV
And just to be clear, that's 0v with and without the jumpers.Leave a comment:

Re: 39L22U Toshiba LED TV
With 1k jumpers in place still no backlight..Leave a comment:

Re: 39L22U Toshiba LED TV
I accidentally touched the DIM & ACD when checking voltage to ground, the backlight did come on then.. What is ACD?Leave a comment:

Re: 39L22U Toshiba LED TV
Yes.. I've just taken the end of the ribbon from the PSU that goes to the video board and inserted the resistors to the plug. Essentially just making a direct jumper to the PSU....Leave a comment:
