Look for bulging electrolytic capacitors on the power board. (If you don't know what I'm talking about, google for "badcaps")

If you find any bulging capacitors, replace them. Also, replace any others of the same type & size (they are often in pairs), since sometimes they go bad without bulging, and if one capacitor of a particular size & type is bad then both of them probably are.

I had this exact symptom on a Sceptre 19" X9G-Komodo II LCD monitor. It would come on for about 1 second, then go off. It also had a burnt smell. Inside I found two bulging 25v 470uF electrolytic capacitors.

I didn't have any new 25v electrolytics, so I scrounged around in my scrap heap, and found an old 9600 bps modem with a pair of 25v 470uF electrolytic capacitors in it, and replaced the bad ones in the monitor with the ones from the old modem. The monitor is working fine, now.

Check the fuses on YSUS & ZSUS boards, if found the fuse blown on that board, just try to replace the board.

61"dlp, a few seconds after turning on I heard pop from the back & the tv turned off. I have 2 short horizontal green lights & 1 long horizontal red light flashing on front of tv. What does this mean?


Power supply board is the first one to test. See if you can spot burn marks or components on the other boards. The bulb could have exploded too.

I have a Vizio p50hdm while watching heard a pop noise and tv went out cant turn back on.I replaced main board and power board and still doesn't come on any Ideas?


The power amplifier chip (which goes "pop" when it goes bad) may be located on the board where the IR sensor is. Sometimes (but not always) you can make the TV come on by holding the power button in _until_ the TV comes on. But that usually only works when the chip is "going" bad. If you heard the pop, it's probably shot. Also, check for a fuse on _any_ of the boards, and possibly a main fuse at the back of the TV.

I heard two popping sounds and now my television will not power on.


A popping sound as you describe sounds as if your tv blew a couple capicators on the main control board. More than likely , you are needing to aquire a new main circuit board.

Problem with the Philips Magnavox 32MF231D Television for elderly lady. She stated she thought she heard a pop when it stopped working. The power light comes on for a second when turning it on then goes...


There should be power fail with the TV. Unplug the device, open the cover, open the metal cover and take a careful look over the alimentation board- its that board where the alimentation cable goes. You say she heard a sound, so, there should be or some burned element, or, most probably, a inflated/exploded electrolytic capacitor. You have to change all electolits that are inflated, according to their position and polarisation.

Heard pop and dell vostro 1000 cut off and will not come back on


Based on the symptoms (Power light on cord is on when not connected to laptop but goes out as soon as you plug it in), the motherboard has to be replaced. YOu may call dell to ask about their out-of-warranty depot or you can call their spare parts sales dept to purchase the motherboard, then find a local tech to replace it.

Heard pop sound, then no power


Sounds like your monitor just fried itself.
Since monitors are hazardous, tricky to fix, and are quickly outdated within a year, by a monitor with a bigger size and resolution.

To answer your question: Your monitor is bricked, and will need to be replaced with a new monitor.

#1 When I turn on the TV the power button comes on then blinks 6 times then goes off for a few seconds then repeats the cycle. I have sound over my surround system during this time but no picture.
#2 My sound would crackle and pop every once and a while until now it does nothing. I have to watch it with the surround sound on.
