Hi Anon,
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
If your TV, flatscreen, or monitor is more than 5 years old it is more like to have suffered a component failure.
Take it to a repair shop.

The ABL circuit to main logic board should be checked. It is a skilled work. In most cased, this board might need replacement. Products powered by electricity
should be serviced or repaired only by experienced professional technicians.
Any attempt to service or repair the product by anyone else could result in
serious injury or death. If
you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock. Instead, contact
the nearest service centre.
Hit the contact us button from the homepage www.tvrepairworld.com and let them know your model and what you're needing they will have them and they respond quickly.
If the problem is same with different input devices and you have ensured there are no loose contacts in power outlet, RC jack, cable and sockets, the TV needs servicing.
the power supply board will need replacement if it has blown fuses. Replacing the fuses will only cause them too blow again unless the short in the power supply is fixed. You can get replacement power boards from www.tvrepairworld.com
If it is grayed out as an option read the owner manual or contact Vizio--they have a good customer service department.If you do not have the owner manual Google the model number with manual to obtain it.
