Sanyo FW55D25F Turns On Then Shuts Down

[JunkmanJimbo]

I have a Sanyo 55" TV model FW55D25F that will turn on for a few seconds and then shuts down. During the time it's on there is a message on the screen that says:
No Channel Is Registered.
Press and hold "ok" button on the remote control for 3 seconds.

I do not have a remote for it.

That's all it will do. During the few seconds it's on, using the buttons on the tv, I can't access the menu, source or anything else.
Any ideas? Thanks in advance.

Backlights issue most likely. You would have to do some voltage checks for us to be certain, though.

I have exactly the same problem, but I do have a remote. The TV powers on and the backlight lights up, the power LED flashes a few times, then the Sanyo logo appears, then the following message appears for less than a second then the TV powers off:

(Channel 1 is displayed on the top right corner)

No channel is registered.
Press and hold "OK" key on the remote control for 3 seconds.

(message is also displayed below in Spanish and French)

The screen is evenly lit and there are no defects in the logo or the error screen. Holding the OK button on the remote makes no difference, as the power shuts down before 3 seconds elapses.

I have removed the back and checked the caps visibly. None of them are swollen and there are no burns, etc. The unit is 3 years old and just went off during use.

I have also tried to change inputs during this startup cycle, but no change.

Hope this info helps point everyone in the right direction - I could use the help myself.

Have you checked the mainboard? I had a chip that was getting out on the same model tv. I cannot remember which chip it was though.

Any chance you remember? Fw43c46f starting up, remote and buttons unresponsive. Shows the input fine. Restarts after 45 seconds.

Does this sound familiar? Trying to update firmware bit can't get into controls.

Exact problem and TV. I'm wondering if a roku (ie Satan) is a/the/part of...the/problem
This is an old post, however can I get a follow up?
Thanks in advance
