Dark band at top of screen...now whole screen

sounds like a wire rubbing on drum and shorting

check connections on top of screen this is becoming a stockfault on samsung tvs

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.

sorry to say unless your prepaird to get it fixed then you won,t solve the problem as the screen as died and needs replacing or for what price they are i would advise you bye a new one ?

This is nearly impossible to diagnose via the Web. It sounds like the logic board is at fault, but not necessarily.

I had the same problem on my tv found a simple solution its been a week and no problems so far.pull out light engine you will find round piece of tape pull it of there will be a #2 phillips screw in about 3 inches turn it clockwise and watch it vanish.i turned mine a little further to assure it would be gone.only took a couple of minutes to do dont know how long it will last though good luck

Two things in your TV can make that popping sound. One is the bulb of course and the other is a capacitor. Have you pulled out the bulb to inspect it? My guess is that you have broken glass in the cooling fan, which is why there is a grinding sound. Most bulbs tend to contain the glass from getting everywhere as it's only the filament inside that pops creating little diamond looking pieces inside the lens. If a surge was strong enough or if the bulb was poorly manufactured, the whole unit can explode inside spraying glass everywhere.

If the bulb looks fine, the pop must've been a capacitor on one of your circuit boards resulting in no display. Since the TV still powers on, your power supply and it's fuse appear to be fine. Check the bulb first and go from there.

Hi , I recently had the same problem which I was determined to fix . So I did a few weeks of research to find that it was the Y SUS board which burns out. I'm sure you realized that the TV gets hot. Personally I think this is why. circuit boards don't like heat and I've learned that the cooling fans are a joke. I replaced the board and got my picture back. I proved the fan theory because after the screen started to act up. I placed a cooling fan near the vent holes on top and the problem cleared right up,It also helps if you lower the brightness which helps out on the heat situation.I will soon be adding a fan with a temp. sensor. This shoud help if your screen has lines when you initially turn the cool TV on.then I have Some other costless solutions. Hope this helped these are great TV's and like our cars we maintain them not throw them away..................................Mr Wiseman

Yes you are correct, I have seen this many times. 6 flashes is the thermal fuse

This is a very easy fix. Your cable box is not grounded correctly. To fix this you need a AC Plug adapter. This will change your TV ac plug from a 3 wire to a 2 wire. This may sound funny, but trust me on this. I have fix a lot of TV in NY doing just this.
