Issue is either with the X or Y sustain board. Look for a cap that has blown or a cracked solid state device on the board. One of them is responsible for the ***** croak you heard.
Hello Check its power supply regulator board. The pop sound you heard may be due to an explosion to any electrolytic capcitors on it. If the line voltage exceeds, this fault will happen. just repalce the damaged component. It is best to replace this board as card basis.
has anyone had this problem? I was watching my sharp Aquos tv and all of a sudden I see a black line, then fuzzzy then black screen then a loud pop, now it looks like colors that sprawl out as if something exploded in one spot inside the screen and it looks like the inside screen is cracked. but nothing hit the tv. it just happend. the sharp people tell me that it cant be fixed or replaced. and they keep telling me i hit the tv! From 5 feet back??? I was watching it. he says..did you see anything strike the tv?? I was like, I am going to ignore that rediculous question because I was on my couch..and no one was in the room! he says the only way that happens is if someone hit it! OMG! i have only had this tv for 3 months and paid $2000 for it. why would I HIT my TV!! no one will help me. I have a master plan warranty on it aswell. they wont help me.
the loud crack sound you heard may be due to a capacitor exploding, look for phisical damage and replace the component with and equal or better component of the same value,,,good luck
I had the same problem. We replaced the Y Sustain board. It was under $200 and not at all hard to do yourself. Remove the back of the tv. Make sure you watch what screw goes where. You will see the board on the left side. The number should be on the bottom right corner of the board. Just watch how you removed the board making small notes as to what goes where. Its really not that hard and you can save 600$ or more
The possibility is that the heat generated by your plasma screen tv is affecting the outer mask of the screen causing the cracks to appear .
Or it may be that the screen has been struck in some fashion and the cracks are a result , do you have small children this is often a cause as they tend to hit things and you are unaware ?. My advice to you is to seek engineers assistance as soon as possible . regards Vortash
