I recently had a really beautiful looking Philips TV come into the workshop. This set was the 32PW9566/79 which uses an MG2.1E chassis. It is a very elegant set which comes integrated into a white, grey, silver and glass stand.

Unfortunately for this set, it lived near the sea (actually almost right on it). And the fault was that it was completely stone dead, with not even the standby light coming on.

Well, of course, that was the clue. After checking the main fuse, it was obvious that the +5V standby supply rail wasn’t working. A quick check revealed that 240V AC was going into the bridge rectifier and that 330V was coming out. This was then fed to a 10W resistor, before going to the chopper transformer (5101). However, there was no voltage on the switching FET.

Removing the transformer from the circuit board revealed the trouble. On one of the legs, the winding had a green spot on it where the copper had corroded. I soldered a link across the break, replaced the transformer and the set came on.

However, that wasn’t the end of it, as the line output transformer was arcing, which meant that it had to be changed. The rest of the set was pretty corroded too. Not only that, but the Defect Errors in the service menu showed 068, 067 and 073 which point to faults in the deflection circuits.

Replacing these will give the set a little more life.
