I'M REPLACING THE IC'S ON MY SAMSUNG HCM5525W

THE PROBLEM THAT I HAVE IS THAT THE TWO IC'S ARE STUCK TO THE ALUMINUM HEAT SHIELD. AFTER REMOVING THE TWO SCREWS THAT HOLD EACH IC, I STILL CANT BREAK THEM LOOSE. ANY ADVISE?

    Are you certain that the legs of the IC soldered into the circuit board are not holding the IC's tightly to the heat sink? Usually all that is there is heat sink paste, and the cooling fin of the IC can be moved away using a thin bladed screwdriver, assuming the IC legs are not stiff enough, and positioned in such a way so as to cause the fin to be pressed.

When I first put my tv on the volume is fine, after a few minutes a click sound is made and i lose the volume completely.


This is caused by a defective spacer under the A / V board. This is not recommended for owner repair, since it involves removal of other PCBs, Sheilds and "spacers" and connectors. On the A / V board ( the one with all the jacks ), is an audio IC that normally runs fairly hot. Therefore, the MFG had to use an aluminum heat sink on the top and bottom of the IC. The problem is that there is a "clay like " spacer pressed between the bottom PCB at the audio IC and an aluminum plate, or heat sink, underneath that sets against the metal back of the LCD panel. Here is what happened; The "spacer " turns into a "sticky goop" causing the whole pcb move towards the Heat Sink under the A / V board. This causes the connections at A / V pcb at the audio IC to come in contact with the bottom aluminum heat sink, thus shorting out the audio IC and then no sound or popping noises. This is common on the D4 and D6 models.We charge about $325 for this repair since it is very time consuming.

03 Mountaineer AWD Premier V8 rattling noise under vehicle


If its the heat shield against the underside.its install with fender style aluminum rivets( if you do it be very careful not to drill into a harness) If its the heat shield around the CAT then you should replace the cat. You can try to repair it with a pair of long hose clamps but I don't advise removing it. In the wrong environment the heat could cause a grass fire. or ignite trash that may get caught or blown underneath. Good luck.

The aluminum plate is a heat sink, there should be solder joints to the board on it. Unsolder them and remove the heat sink to make it easier to remove.
