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

We have our TV in a box for about eighteen months...never used it until today. When I turned on the power switch, smoke comes out the top of the back panel and disappears when the power is turned off. Any suggestions? Thanks,
Bob

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?

Visio 1080p screen went light


Our Visio 42" flat screen TV did the same thing. It didn't happen that often but sometimes it would go darker or the sound would go off until I changed the channel or turned TV Off then back On. I contacted Visio through my warranty and they sent me a flash drive to install info on my TV. Did not fix the problems. A year later before warranty ended I contacted Visio again. They sent a huge box for me to pack my TV in to send to the warehouse where they fix everything. It took about 2 wks. to get it back. Worked fine for about 4 months and the problems continued. I will not buy another Visio TV. I found out that they had many problems with several models.

If you have tried using different input devices, looked for loose contacts
in power outlet, RC Jack, cable and connectors, the TV might need service.

Horizontal lines and color problems?


this could be a format issue. When you change the channel do the lines go away ? If so try to go into the cable box (assuming you have a cable box) and reset your formats and exclude the format causing the lines.Make sure if your using component cables all colors match up.If this does not fix it replace your component cables/hdmi.All else fails unplug your TV wait 5 min. and plug it back in. Hope this works for you.

No audio on pasma when cable set box set to certain channel


In that case two things might be happening. 1. HDMI/DVI cable you using might be faulty you want to change that or 2. The HDMI input of your TV set might be the problem. I will suggest you use component cable instead, I am talking about the 5-color-coded (green, blue, red and red/wihte) cable to connect the set top box to your TV.

Verticle lines on screen


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.24001fc.jpg
