Either the sleep timer is set, or the power supply unit is faulty.

Hello
Your flat panel TVs picture tube base board has soldering loose contact with it. Just unplug your TV from AC mains socket, and open it. Pull out the picture tube base card from the picture tube neck. Pull it out straight, no shake must be there, as it will damage its connecting pins.
Normally, loose sodering are very difficult to loacate, as they will be quite micrscopic in size. Just resolder all the suspected loose sodering point on that board, by applying a little more solder. This will solve your TVs problem. OK.

JVC LT47 that picture goes black (sound fine) after being on for awhile. Can turn TV off, then back on & it's fine. But then happens again about ever hour or so.


Hello
Hello
It is due to some loose soldering points [dry soldering we say it technically], in the power supply section of the TV. Just check for it. Check the solderings of all components, that will heat up to an extent when the TV works on. Repeated heating and cooling may make solderings to the terminals of that components to get loose. Just resolder all the suspected solder terminals, by applying a little more solder, without making any solder bridge short in between adjecent solder terminals. This must solve the problem to your tV. OK.

My TV pictures turns black afetr a few hours but I still can hear sound perfectly!!!


It sounds like your rptv lamp is going out. If this is an older DLP this is most likely the cause. You can get a replacement at www.laptopsforless.com part number BP96-00224J for $151. If the tv is still under warranty, I would have them do it, otherwise replace it yourself. If so here is a link to give you step by step instruction. Please give me a good rating. ;-)

Samsung 40 no picture


If it is only 6 months old you probably still have a warranty. This is definitely a hardware issue, and unless you are comfortable taking your new TV apart, I would contact Samsung for repair.
