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.

How to remove the DMD shield on Mitsubishi wd65733


Don't know why you are removing it; if you are replacing the bulb I suggest you use the bulb replacement that is complete with new housing already.

The sound on my toshiba theater view wont work i checked both the speakers and they are fine. Is this a simple fix?


hi,
If speakers are ok then the sound output ic of your tv is faulty. If you have basic knowledge in electronics then you can replace the ic. You can find the ic by following the wires from the speakers. It will end near the sound out put ic. The ic will be fitted on an aluminum heat sink. Note that number of that ic and get a new one from the nearest electronic spare part shop.For replacing the ic you need some tools like screwdriver de-soldering pump soldering iron, solder etc. All these thing will get from the spare part shop, if you don't have the same.Be sure to open the tv only after half an hour after dismantling the power because electrolytic capacitors inside it will store the power for some time.
ok

Replacing the ic's on a samsung hcm5525w. ic's are stuck


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.

Fame, The symptoms you're describing appear to be convergence failure and probably only one of the convergence amps. That unit uses two STK392-040 IC's and it is HIGHLY recommended that you replace both - not just the one. The convergence amps are mounted to a large aluminum heat sink with a heat sink compound for the greatest heat dissipation. My personal experience with this particular model has been that replacing the IC's only restored normal operation in 9 out of 10 sets as opposed to having to replace any other corresponding resistors or other components. In laymen's terms it's probably only the convergence IC's that need replacing. I strongly suggest that you not tackle this one by yourself unless your are fairly skilled at soldering. Too much heat on this multi-pin IC will destroy them and they're not cheap.. It's also a bit difficult getting the old ones out. If you don't do the job yourself find a good reapir shop and ask if they have the IC's in stock. If you're not sure where to find a reputable shop call NESDA, (National Electronic Service Dealers Assn.) They can refer you to a qualified member shop in your area... If you do tackle this yourself, order only the Sanyo originals from places like B&D Electronics, Vance Baldwin, ACME or Samsung. And use a fairly good heat-sink compound...
