Re: Toshiba 50L5300UC delayed power up
Sorry - yes I did try that too but it had no effect.

Re: Toshiba 50L5300UC delayed power up
Okay thanks for the help. So should I get a replacement main board or is there any any last things I should test first?

Re: Toshiba 50L5300UC delayed power up
Sorry for the noob questions - I've not worked on tv's before. Is the motherboard the other board here, i.e. the one not pictured?

Re: Toshiba 50L5300UC delayed power up
Hairdryer had no effect after five minutes.
Is there anything here that's likely to be quick and easy or would you say I need to get a whole new board?

Re: Toshiba 50L5300UC delayed power up
Where should I backtrack to test for that? I've tried finding the circuit diagram for the board but with no luck.

I'll try and get the tv running and see what they are then.

Re: Toshiba 50L5300UC delayed power up
Yeah sorry - being a bit dumb on that one. Here are the voltages on Connector J206 which all seem to be d.c. apart from NC on pin 8 :
1 12V2 12.5v dc
2 12V2 12.5v dc
3 12V2 12.5v dc
4 GND 0v
5 GND 0v
6 12VA 12.5v dc (I thought this one would be ac)
7 GND 0v
8 NC 1.8v ac
9 GND 0v
10 5V1 5.1v dc
11 ACD 3.5v dc
12 PWON 3.3v dc
13 BLON 0v
14 5V1 5.1v dc
15 DIM 3.2v dc
Thanks for the feedback guys - please let me know if you...

Re: Toshiba 50L5300UC delayed power up
I have 3.5V on J206. I'm guessing that means something wrong in the rectifier circuit?...

Toshiba 50L5300UC delayed power up
Hi guys,
I'm having trouble with this LED TV for the past six months.
When I turn it on - nothing happens and then between five minutes and a couple of hours it will come on and work fine.
My research online seems to point in the direction of a bad capacitor but none have popped or leaked.
I'm thinking my next step is to take a leg of each cap out of circuit and test the value but would appreciate feedback from some more experienced techs on this. Should I test anything else first?
Please see attached picture of the power ...
