Your convergence chip, or chips are gone. Easy to replace on this TV via front access panel. Remove the front speaker panel open up the access port and remove the front board. Get the IC's online and solder them in and replace, Make sure to check all of the resistors as they also blow and replace as needed. Make sure to use a good thermal paste like MX2 as this is the baser problem as to why these fail (you will see what I mean when you remove the chips)

    Additionally to my fix above, DO NOT REMOVE THE REAR PANEL.
    These TV's have a sort of self destruct issue with the dvi port if you open the rear of the TV without taking the proper precautions, and there is no need to do so when you replace the IC chips.

I have a Philips 50 DLP HDTV MICRO DSPL and I figured the lamp was about to go out because after you would watch tv for about an hour and a half the picture would begin to flicker so I replaced the lamp...

A couple of things to check here. When you replace a lamp some TVs require you to reset the lamp hours meter in the settings in the menu (More common in projectors). If you do not do that then it will only run so many hours before shutting off again. If it is that, you should be able to turn it off and have enough time on the screen to reset that. If that is not the case then you should look into replacing your power supply board.

Everything is connected but there is no sound coming through

was it working before you put the vehicle in storage? if just the audio is not working, there is no code. as far as i know pioneers do not have security codes. you might want to check your speaker wires and speakers for shorts and bare wires.

My rca r52wh74 turns on for 10 secs then off.

was the storage unit climate controlled? If not then it's most likely due to heat and or humidity in which case I would suggest cleaning out the tv from the inside if you want to spend the time to do so but there is a good chance that the tv will need to be replaced.

Need driver for PRAKTICA DC Slim 315

Sounds like you have set it to PC Cam mode. If you put it in Mass Storage mode, you don't need a driver to use it.

To put it in Mass Storage mode: Hold the Mode button while it's turned on. Select the 3rd option that appears (looks like a Swiss army knife) by pressing the button to take a photo.

Scroll down and change USB Mode to Mass Storage.
