See if this works: I called Vizio with my problem and was told I needed a hard reset, and this fixed my problem: I unplugged the TV; held down the on button for one minute, then plugged it back in.

Hope this works for you, if it does, let me know by coming back and voting. Thanks!

If both video and audio are missing, the problem is likely the main power supply. Switched mode power supplies are very efficient but also very fussy about component quality and one of the cheapest components in them, the electrolytic capacitor, has been chosen on cost alone, they tend to break down chemically due to the higher frequencies many of them handle. There are points in the power supply circuit that stresses these caps and if they were not bought for the use to which they are put, they will go bad after a fairly short period of time.
These supplies are often bought assembled and if so, they will be on a separate circuit board.
If you wish to experiment in verifying the source of your problem, you will need some 'freeze spray' used for electronic troubleshooting. This chemical is in smaller pressurized cans costing $5-10 US and can be found at electronic supply stores and I would recommend buying a pair since they are quickly depleted.
You will need to remove the back panel of your set and supply it with AC. Look for a smaller circuit board with larger than average components on it, particularly larger 'cans' and block-like chunks which are chokes and transformers. Keep your fingers clear of any bare parts on this board, they can have painful voltages on them. The larger capacitors (cylindrical cans) are rarely at fault; direct short bursts of freeze spray at the smaller capacitors and wait 10-15 seconds for the spray to 'soak in' before spraying the next. You can identify capacitors by their appearance and markings which will include + and - marks along with values such as '47uF/50VDC.' If you are lucky, when you find the failed cap, the set will turn on temporarily.
Then you can decide if you want to pursue a replacement board or possibly a repair. If you buy a new board, don't discard the original since it is quite possible that the new board will fail eventually too. Smaller companies are offering repair of such boards but since I am no longer in business, I can't recommend myself or anyone else. Post (comment) back to this thread if you require further help.
Good luck-

Is the Amber LED near the power putton on? There is a problem with this series that the Microprocessor Reset Supervisory chip goes bad. On the main PCB (With all the RCA jacks). Top left about 3 inches in from the edge, the part is U26 ASM809 (alternate MAX809M)
Have fixed this many times. but as others have said the SMPS Caps need to be checked too.

Hi, I am thinking of buying a used Visio L32 at a really great price.


I have never heard of pressure point lines. This particular model of Visio has a lot of problems wih the lcd panel and the lcd control module. Major problems and major expense. In my opinion a very low quality product and I will never purchase a Visio.
