Hi, after aprx 1.5hrs of playing a dvd the home theatre system switches off, i then turn it back on and then aprx 1hr later after playing a dvd it switches back off, i repeat the steps above and the time...


Sounds like you have a cold solder connection somewhere on the main board or power supply. It opens when the junction begins to heat up after prolong use. It probably corrects itself when the unit is cold and the junction re-connects. Your best remedy is to inspect the boards and try to locate the bad solder connection. You can do this, but please be careful when working on live circuits, by using a non-conductive pointed tool and poke at suspected joints on the circuit board - if the unit begins to work again, Bingo, you found the problem. Good-luck!

Tv keeps shutting off and going back on by itself


Cold solder joint in the power-supply board, once it heats up it expands and shuts off. Open it up and start scanning the board for defects and hit them with a hot soldering iron and a dab of solder.

No picture


Common faults that give you no picture and sound on Plasma are often related to Sustain board, buffer and cables problem.

In this case the cost will be affordable, ans surely worth.

In the unlikely eventuality that instead you have a faulty plasma screen , or a faulty digital control board (main board), the cost of repair may be high.

The only way to find out is by having the TV inspected by a technician.

The most common fault that gives you no picture and sound on plasma is Sustain board , lower buffer, or connector, that is repairable.

Samsung DLP HL-P5063W. . .no lamp!


You will need to have it diagnosed if you do not have the service manual, or the knowledge of how these circuits work. I can tell you to replace this or that but it would be a guess! You need to start measuring the voltages on the ballast circuit, as I have seen door switches, fan sensors, heat sensors cause all of your symptoms as well. Good Luck
