VIZIO VO42L FHDTV10A Issues

[jtandrew]

Hi,

To start with I am new and thanks for your patience. I have VIZIO VO42L FHDTV10A that started not showing any picture, no backlight and no sound.

When I have it plugged in I get an amber power light. When I press the power button the power light switches to white and nothing else happens.

Please let me know what my first steps should be for troubleshooting this issue. I can get pictures on here in the next day or two but I do not have any right at this moment.

THANKS MUCH!
Jim

Can you turn the TV off with the remote? Is there a U33 on the main board? Have you checked the voltages out of the power supply?

I just checked and the TV will turn on and off with the remote. I am going to look for a U33 and check voltages.
Thanks,

It's not the same problem then, sounds similar to 2 seconds to black.

To verify, with tv powered on and a source connected hold a flashlight to the screen - can you see an image? If so, read below.

PlainBill wrote a very good troubleshooting guide for 2 seconds to black, it has been re-written several times to scroll to the last version near the bottom.

Good luck with your repair, if you need further help then start a new thread, it doesn't cost anything and is better for search purposes.

Excuse me. I've done enough here in my own right that I don't need to borrow the glory of others. retiredcaps wrote (and rewrote, and rewrote) that excellent troubleshooting guide.

Apologies PlainBill - don't ask me how I got the both of you mixed up.

I second your comment on that being an excellent guide.

It's common - great works are often attributed to the wrong author. Last week I found a list of outstanding Science Fiction works by various authors. Under the section for Arthur C. Clarke was 'Nightfall' - written by Isaac Asimov.
