Whestinghouse 50inch,turn t.v. on there is sound and no picture and it's only 5 months old. What can I do?

Call your LG dealer for a service call out, this sounds like "sparklies" adjustment is required. If adjusting does not cure the problem then there is a software solution that the engineer can apply to cure the fault. There is nothing you can adjust yourself without removing the back cover.

Unplug,replug the tv back about an hour later.Go into the tv menu,go to SOUND,go down to reset it to back to factory setting.The sound now should return,not,than ur tv the Tuner board have problems,call for warrenty serviced.

I am afraid it sounds as though either your backlight or power inverter has gone faulty, may be worth contacting alba to see if they will honour the warrenty (unlikely but worth a go) otherwise maybe try your home insurance to see if its covered, failing either of these options, if you feel confident doing so, disassemble the tv and look for any signs of visible damage (capacitors leaking or any components looking burned or scorche, and replace. Try looking for any panel markings which will allow you to search for a price to replace the whole unit.
Unfortunately I cant give you and hard and fast cure, and it is very difficult to tell whether it is the inverter or the backlight has gone (having said that, if you are getting picture at the very beginning, it may suggest that the inverter is getting the power to the backlight ok, which may suggest its the backlight at fault.)
Hope this helps.

This is one common error that you can fix yourself instead of sending it to the repair shop. Try Easy and Complete Guide to Wii Repair. This guide is very helpful and contains all major problems related to Wii. It also has several pictures and instructions and would help you solve any problem very easily. Apart from all, it is very cost effective and you would save hundreds of dollars on Wii Repair Manual Good luck.

It will require in-depth troubleshooting to narrow down to find out which board is bad. Are you going to do the repair yourself and have all the tools?
Please read below:

First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.
