Smoke coming back


The main dc reservoir in the power supply must have burst. This capacitor 47 to 100 MF/400V also releases lot of smoke when it bursts. Most of the times you just have to replace it and the tv works fine.

Why is there smoke?


Kindly switch off the TV, switch off power, and remove plug. The TV needs servicing by a qualified service technician.

Philips tv smokes


Do this only if you are a qualified service technician:

This problem can come if any moisture has entered or is formed inside the TV.

Switch of the power outlet, and remove the plug. Open the back cover and check what are the parts burnt visibly. If it is in the SMPS area, you may require a thorough check on the load and replace all the burnt parts by looking through a Service Manual. Anyhow, this might require attention by a qualified service technician.

I had the TV upside down for about 5 minutes to take the stand off of it. I put brackets on to mount on my wall. I put the TV on the wall then plugged the TV in. There was a sound and then a puff of...


Whoops, did you not use the right length screws.

The mounting bracket screws will short onto some electronics if you fit screws that are too long and from your superb description, it sounds like you did everything right but do not mention what screws you used.

Smoke coming from a TV is always a sign that something has burned out and unfortunately it is never a fuse. The TV will need fixing, there is no chance of it still working after it has smoked.

If you are lucky, it will just require a power board but you need a TV engineer to look at it as it is not something that you can usually do yourself. Even if you bought a new power board and installed it, there is no guarantee that the main board/processor board or inverter has not blown as well and this is why I recommend a professional looks at it.

Unless your house insurance covers the damage (if the excess is not too high).

Light colored smoke comes from top of TV when first turned on


If it's like my problem with this set, the power supply gets really hot and essentially melts all of the contact cement they smear all over the PCB to keep things from coming loose. That didn't affect the set's performance and ceased after just the first few minutes out of the box. But recently, we had the same thing happen and I found that all four of 3300uf caps on the board had cooked-off, All of them were swelled and two of them had sprayed their liquid contents around their enclosure, creating the smoke.
I replaced all four of those, but the set will still not power up. I'm getting 120vac all over the "Hot" side of the board and nothing on the "Cold" side. How do I test the three PC817 optocouplers that separate the two sides of the board?

Sharp Aquos Won't Power On


I have the same problem with my My LC-42D62U WHen i watch certain DVDs, (so far it happened on SAW III and RUNNING SCARED) during certain parts of those movies my TV will turn off and i cant turn it back on unless i unplug it and plug it back in. It only turns off on specific parts in the movie, i have no idea why...like the same exact parts...so i pretty much have to pause the movie with my remote once my TV turns off then when i power the TV on again just resume the movie and its fine...but if i rewind to that part again it'll power off again SAW III only had one part like that....but RUNNING SCARED had about 3-4
