I have a 50L1450U model Toshiba and the tv only powers on

Customer Question

I have a 50L1450U model Toshiba and the tv only powers on sometimes and when it does we have to wait a long time. When I push the power button on the side nothing happens.
I've taken it apart now and see only 2 boards inside. I'm guessing the one where the power button is needs to be replaced?

I would also like to know where to buy these parts if needed. Thanks
Expert:  Anthony_Infotech replied 1 year ago.

OK the first thing to do is examine the capacitors on the power-board they look like this <<click

You are looking for ballooning\leaking\raised domed tops powerboard is found by tracing power-cord to it

Let me know about those first

I don't see any of that on the board that connects to the power cord

They are lying flat on this board just examine each closely

Expert:  Anthony_Infotech replied 1 year ago.

I have marked them all in red

Customer: replied 1 year ago.
I have examined them closely, they do not seem to be any ballooning, leaking, or domed.
Expert:  Anthony_Infotech replied 1 year ago.

OK the power-light in the front of the set is that lit or blinking?what color is it?

Customer: replied 1 year ago.
There is no light at all until it finally comes on.
Expert:  Anthony_Infotech replied 1 year ago.

It really seems like that power-board is bad do you think you can replace this?you just unplug and unscrew from the chassis, order by part-number only found on the board itself www.shopjimmy.com should stock it

Let me know if you need more help

Were do I find the part number for the board? Is it possible the fuse is that is really close to the power cord inlet is blown? Its completely white so I don't know how to tell if it's bad or not.
Expert:  Anthony_Infotech replied 1 year ago.

No its not the fuse there will be a series of codes on the board you have to try them all OR to get an idea of the number you need go to shopjimmy using the model number

Customer: replied 1 year ago.
ok, let me give it a shot and I will let you know.

Just to be sure, you are referring to the board that the power cord connects to correct? The reason I ask is because the power cord connects to one board but the power button is connected to another.
Expert:  Anthony_Infotech replied 1 year ago.

Its the board the power-cord plugs into yes

Expert:  Anthony_Infotech replied 1 year ago.

Board will cost around $100

Please before you go remember to rate the info positively 3 to 5 stars thank you ,you can still come back here anytime upto 30 days

Expert:  Anthony_Infotech replied 1 year ago.

How is this working out please?

Customer: replied 1 year ago.
I'm ordering the part tomorrow and should have it by the end of the week. I'll let you know asap. Thanks
Expert:  Anthony_Infotech replied 1 year ago.

OK fine

Customer: replied 12 months ago.
I installed the new board but nothing has changed?? What else do you suspect could be the issue? What is the other board called?
Expert:  Anthony_Infotech replied 12 months ago.

So you have replaced the power-board that is this one <<click

If so you do have exactly the same symptoms?because that is really odd if you do, usually when the main-board is bad it stays off with no power-light, the set won't usually come back on however there really isn't anything else it could be here so you will need to hold on to that power-board for now and order the main-board that is the one with all the INPUT connectors attached, again order by part-number only found on the board itself
