Samsung UA46B8000XY TV partly flooded making popping noise. Water reached 50 mm up screen. Dried out for a week. At turn on the display works but then turns off and get popping noise..

Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Tv have a colors wheel,hearing a humming or buzzing noises or black&white picture flashes with the picture,the colors wheel is dead.Hire a tv tech. to replaced the colors wheel,it pretty hard to replaced the colors wheel,because have to have take out alots of machanical parts,before even can come to the colors wheel itself to replace it.

loud pop then no picture. still has sound 50 in samsung plasma mod s50hw-yb02

the problem with your tv is the color wheel
not the fan let me know if you need help to take it apart...
I do repairs for samsung tv and I fixed a lot of them before..

When you said "huge crack on the inside" you mean the screen? if so let me tell you that the only way to fix it, is replacing the screen, really expensive, like $800-1000 just parts.
My recomendation is that you pick up the phone and play it hard with Samsung, they dont want to fix it under warranty because 90% of broken screens are due to End User fault.

electric and water are a bad mix as you know my advice to you unplug tv put it in very warm room for about 3/4 days do not plug in hopefully it can be saved.adrian

sounds like the lamp has shattered. check the lamp

Hi there.My 3yr old son water gun our 50" lcd tv sony bravia.I nearly have a heart attack.LOL.There were black mark at the bottom of the screen and when I touch it it's moving around.I realize that it was the water.So I didn't do anything.When we don't watch tv I turn it off from the wall.I kept doing this and after two weeks I notice that the black mark has gone.I don't why>So may be you could just leave as it is...good chance it may to away itself.I hope this helps.thanks.

unfortunately, the board of your mobile phone has corroded. When the water dried up rust was developed. try cleaning the board of your phone...

the person you talked to at samsung is more than likely a customer support rep that does know anything but what his computer tells him. i have seen this symptom several times in many makes and models. if you can give me your full model number i will give you a part number to fix this issue.
