Blue screen, no picture. What's wrong?


The board where the power button is located (same board for the other buttons too) is probably bad. It's all one board, which tells the power board to come on. If this happened after a power surge, and you're not using a surge protector, multiple boards can be bad. (You can't just plug these fragile TV and Blu-Ray players into the wall outlet. Eventually a surge will destroy them). Ps... A lot of people are suddenly making this same complaint with Vizio TV's.

Today my power went out for a split second and came back on I turn my TV back on it makes a high pitched whining noise and the screen wont turn on. Cant add picture but model number is MW30G71.


unplug your tv. let it sit for a good bit. 1/2 hour did your power just go out or did you have a power surge then no power. surges cause the grid to go down for a second too and that causes problems too. surge protectors are good for everything. also are you on cable? if so have the cable company check they're filters into the house may be an issue but check the tv after a half hour unplgged and then plug in and turn on normally? sometimes it needs a reset time period before the fuses inside will reset themselves.

TV won't work after storm


ok lets try this hit the power button on the DVD player some go into stand by mode and when power is interrupted you have to push the button manually also reset the surge protector next get a lamp that you know works and unplug the tv and plug the lamp into the socket where the TV was plugged into turn on the lamp, does it turn on? yes then something wrong with TV again may have been in stand by mode plug back in and try pushing the power switch on make sure the TV if it has a remote is on the right im put to get a picture say like a satellite or cable or DVD player. hope this helps.

Tv popped and picture went out


im srry to tell you that you picture tube blew in you tv this can happen from many things as simple as a defective one .. to a bad power surge in your house ... if it is under warranty they will fix free of charge .. if not you'll have to get a new tv .. a new tv in most cases is cheaper then tryin to just by the tube .. oh and if its not under warranty .. you could always just say it surged and claim it on you home owners insurance =]

on the back of the TV where the power cord plugs into the back of the tv there is a small black on/off switch- it's not as obvious as you would think.... but that was turned off. Not sure how that happened since the back of the Tv was never touched when it went dead- but I unplugged the cord from the back of the tv and from the outlet and reset that switch and it worked.

The electricity had gone off due to a fault somewhere in the area which switched the tv off (it was on and working fine). the electricity was off 4 about 10mins and then came back on, then went off, then...


Hi.

Modern sets dont like power surges which is what happens when supply goes on & off.

I would think that something is damaged it will be expensive to repair.
My advice would be get A shop to check it for you If you can ask them to see if this problem in there opinion is due to power surge.
If you have house hold insurance new for old make A claim.

Hope this helps.

Samsung hcn653w power surge


If the set went dead during a storm and will not power up at all, first try unplugging the set and waiting an hour or so, and then plug it back in to a working outlet and try turning it on. If the set still will not respond, your power supply has stopped working and should be serviced by a qualified tech familiar with Samsung projection sets.
