Having problems with your Flat Panel Televisions ?

I have a Samsung HP-5064 plasma TV. Over the last month, it occasionally would have sound but no picture when you turned it on but the picture popped on after 2-3 minute. I now have no sound or picture. I unplugged power for a while and than plugged it back in but still no picture or sound. What are my possible problems? Doug



Answers :

This is typical with many sets as there is a high possibility that the components over a period of heating and cooling , tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs.

Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points. Please find below two links for tips on poor start ups, as if the set is totally failed the SMPS might be faulty

Sylvania 13tv/vcr, has this code on the tv screen (8c1-0.19) when turned on. The TV has a picture,but no sound. The power supply seems to be okay, because when it is turned on it will play for hours,but without sound. There is intermittent use when the power button is applied, if it does not work the TV must be unpluged and pluged from the outlet to turn it on and off. Do you what this code is, and why is affecting the TV?


The fact sound works for a moment when power button is held and that you have to unplug to turn off or on means not a circuit problem but that the set is likely in the tech mode or service adjust mode.I think the best way to resolve this is c ... Sylvania 6313CE 13 in. TV/VCR Combo

However, playing the xbox or watching a dvd, it looks perfect. I found that when we unplugged the power cord, it would be fine for a while. But now that isn't even helping. Today it seems that the sound went as well! Time for a new one-or simple fix?
