Change the batteries in your remote. If your cat was laying on a button it could have drained them.

Here's tip - you can use your camera on your cell phone to see the IR signal coming out of your remote. Point the remote at your cam and press "On" or any button. You should see a bright flash with every key stroke.

SOURCE: after 3 min it turn off wait 1 min it come back on

You need to check the output voltages of the power supply to see which one goes off. It may be due to short circuits some where.

Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board.

I do not think it needs replacement, rather some defective capacitors are causing this issue.
Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors).
After replacing these capacitor(capacitors) most likely the normal operation will be restored.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Good luck.

If audio is OK, the problem is with its back-light. Check and replace damaged component/s at its backlight inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Surf the site with patience. Pull up older posts. Do a search by type in the brand name of your device at its search box. It will be best to replace the inverter board as card basis.

Vizio VA 26 L HDTV10A black screen after on for 3 seconds. Replaced power supply and Mainboard.


There remains only the fluorescent back light tube(s) or the inverter that supplies high voltage for it (them). If you had no warning flickering, I would look for the inverter board.

My Vizio 42in. is really fuzzy


If the picture is clear when using a DVD and remains "fuzzy" only with cable, then either the cable is bad or the up-conmvert from standard def to Hidef is creating the "fuzz". Depending upon the method used by the set to perform the "up-convert", the noise you are seeing may be normal.
