>>I replaced the diode on the SSB that Philips says to replace for a dead
>>set.
>>It worked for several days in the shop before I put the back on, and a
>>couple days with the back on, before the customer picked it up on the
>>24th.
>>He got help putting it back in place this weekend, and it worked for about
>>a
>>half hour then quit. Just like last time, he was able to turn it on again
>>for short periods
>>but it won't stay on now.
>>
>>That diode is what the factory said to replace for that problem and it
>>sure
>>seemed to do the job when I ran it for days here in the shop. The other
>>thing they said to do was replace the whole board, if I didn't want to try
>>to do the tiny diode. He felt the board was way too expensive when I
>>called
>>him, so we went with the diode.
>>
>>Has anyone done just the diode and had the set stay fixed?
>>Has anyone replaced the board and NOT had the set stay fixed?
