Question about Panasonic DMR-E55 DVD Recorder
Hiya were do you get the extra heat sink from i have looked at mine and it hasn't even got any vains it's just a small piece of metal please can you help Best Regrds Tony
Look on ebay or Google for a TO220 heatsink. Believe it or not, the thin metal strip you have referred to, is in fact the manfacturer's attempt at heatsinking the regulator. It is all but useless. There is one here that would be ok.
You will need to bend the veins to squeeze it into the space available. Do this carefully because they can easily break off when you bend them.
Alternatively, consider bolting the regulator to the inside of the cabinet instead. To do this, remove the power board, remove the old regulator completely. Solder flexible PTFE covered link up wire to each pin on the regulator and leave these about 4 inches long, Use heatshrink sleeving or plastic tube to cover all the solder joints, Drill a small hole in the bottom of the cabinet. Use some heatsink paste, a mica insulator on the back of the regulator and bolt it firmly to the inside of the cabinet under the power board. Solder each PTFE lead to the where the pins would have been soldered under the board and then neatly fold the wires under the board before refitting it. I have repaired about 6 of these using this method and I can confirm that the regulator hardly gets warm as the whole cabinet acts as the heatsink. Although it is more difficult to do.
Only attempt any repair or modification if you are confident in your competence in basic practical electronic work.

WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.
The "CPU" or central processing unit, otherwise known simply as "the processor," is the primary "brain" of the computer.
Processors are very finely engineered components that are not repairable.
But replacing a failed processor is an option for the owner of any model Compaq Presario desktop computer.
Just check with HP/Compaq for the correct size and speed of processor for your motherboard before purchasing a replacement.
Turn off the computer and disconnect all cables.
Remove the cover.
Lay the computer down flat.
If there is a plastic hood covering an exhaust fan, remove it by pressing in on the indicated release tabs.
Examine the processor assembly.
The processor is a square chip that is covered by a metal heat sink with fins.
A fan will often be mounted on top of the heat sink; unplug its connection to the motherboard.
Two clips usually secure the heat sink assembly to the top of the processor.
Gently press down and slightly away on the flat end of a clip to release it.
Avoid using a screwdriver to release a clip a slip could scratch the motherboard.
Release the clips and gently remove the assembly.
The heat sink should separate, leaving the processor behind in the chip holder.
Clean the bottom of the heat sink.
Use a paper towel and a dab of solvent cleaner to remove the old thermal paste.
Set the clean heat sink aside.
Lift up the lever to unlock the old processor and remove it from the pin mount.
Insert the new processor chip.
Align the pins on the processor to the "cut off corner" or dot on the pin mount.
The processor should drop into the pin holes easily.
If the processor won't drop in easily, check the pin alignment.
Once the processor is inserted correctly, pull down the lever to lock in the chip.
Apply thermal paste to the bottom of the heat sink.
Apply enough paste to cover the area of the small gray rectangle on top of the processor.
Apply the paste with a spreader made from a piece of flexible plastic.
Spread the paste evenly to a thickness of two sheets of paper.
Check the heat sink mounting alignment and lower the heat sink onto the top of the processor.
Reinstall the mounting clips.
Reattach the heat sink fan to the motherboard if necessary.
Plug in the computer and monitor and boot.
If the machine won't boot or it emits warning "beeps," unplug the power and monitor, and troubleshoot your work until the computer boots successfully.
Shut down again and replace the exhaust fan hood.
Close up the computer and reboot.
Hope this helps
