My sanyo tv is not getting power to it not even the red light comes on

If your able to remove the back and see if the main fuse on the power board is blown, if it is replace it and see if it blows it again, if it does you have issues with the hot side of the power board, unless your fairly familiar with electronics you may want to replace the board, they can be found on ebay or shopjimmy...If you don't see a blown fuse your going to need a multi meter to do some tests to figure out what board is bad, as it could be main or power supply making the set dead

the light of LCD (liquid crystal display) is not working

Most likely your inverter board has gone bad. Really the only fundamental difference between LCD and LED TVs is the back light technology. They both use sheets of LCD crystal cells that open or close what are called shutters, to allow colored or non-colored light to pass through, the only difference is that LED TVs use light emmiting diodes(LED) to create the back light that causes the TV to display the picture and LCD TVs use compact fluorescent bulbs (well tube bulbs usually) to create that back light. CCFLs need a high voltage to vaoprize the mercury in the bulbs to start working and since the AC in your TV transformed into dc when it enters the TV that dc needs to be transformed back into AC because those bulbs need a high frequency to operate. This is accomplished by an inverter board. Most likely if you cannot see the picture of your TV then your inverter board has failed. You can easily check this by turning your TV on to something with a picture(broadcast TV, a DVD player, your computer playing a video, a video game console, etc...) and placing a flashlight up against the screen itself. You should be able to see part of the picture. If that's the case you most likely need a new inverter board. eBay is typically the cheapest place to get that board, but unfortunately, sometimes Electronics are poorly engineered or manufactured, causing the vast majority of a certian model or several models (if the manufacturer has a habit of using that same board in a bunch if different models they produce) to fail, and so aourcing the boards you need to repair your set may be difficult to downright impossible. The only thing you can do is to figure out what that board's part number is and search it online starting eBay and then moving to google. It maybe easy as doing one simple search on ebay, it may take hours of research on the web, or all the available spare may hve already been snatched up by other consumers who also had their sets fail. If that's the case, there might be somewhere that is selling board refurbishing services. You send them your board, they test and replacing a failing components and they ship it back to you.

Good luck and please give me an up vote if yoj found any of this helpful.

I have a vizio E321VL its an LCD and recently the screen went black. When I turn it on the vizio logo comes up and backlights come on but then screen goes black. Ive tried changing input or changing channel but nothing comes up. All buttons and functions work its just the screen. I want to say its the backlight but why woukd they come on with the vizio logo at first? Ive had this TV for less than a year.

Vizio had problems with the processor boards.
If you had no lights, I would say power supply, Logo with lights, I would go with Processor board, check ebay. It is called a main board and they run about $60. That is what I would get, but then again, how old is it? If I could replace it with a new for $250 why take a chance for $60. I have pitched them before.http://www.ebay.com/sch/i.html?_odkw=E321VL+main+board&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR2.TRC1.A0.XE321VL+main+board+refurbished&_nkw=E321VL+main+board+refurbished&_sacat=0
You tube also have videos if you are a electronics repair person.

Audio works but not the video.

the thing about these consumer tv's is that they use the most grossly cheap electronic components in them so that they wear out quickly. the main power board is faulty, could e several small capacitors or a transformer , but a electronics service tech will need to do the work unless you have used a soldering iron and are comfortable with it. A replacement power board may be found on ebay for your model tv.
and last purchase a backup power supply to condition the electricity so that the tv will get smooth electricity from now on. hope this helps you . good day
