Hi there,<P>I have two problems with my Pilot TV 37. I recapped it and changed many resistors (a few of which were either 100%, the rest were 15% to 20% over their values).<P>I am using this TV as follows: the mains being at 50Hz, I use a PAL/SECAM VCR (625 lines 50Hz). The output composite video signal is fed to a Radio Shack NTSC modulator which outputs RF NTSC 625 lines 50Hz on Channel 3 or 4. This works quite well with my Motorola VT 71.<P>However, I have the following two problems with the Pilot:<P>1) The best picture in quality won't tune exactly when sound is loudest. That means, either I tune on a good picture but weak sound, or I tune on great sound but gray or very instable picture. I wonder if the IF transformers are correctly set. Anybody knows how to set them, or verify if they are correctly set ?<P>2) The picture is amazingly unstable, as if there was some sort of echo of the picture over itself. To explain this: when I check the video signal on the Sync Separator (V9, a 6AU6 tube), I can see this signal, but it's like if its curve was copied over itself randomly. The grid of V9 appears all negative, around -1V. The "echo" effect looks like random "copies" of the signal appearing much darker on the scope. I'll try to picture this if I can. Despite this strange signal, I sometimes manage to see something on the screen, but it's unstable horizontally.<P>I tried to use another 6AU6 and 6BA6 for the Sync Separator and Video Amp but this didn't improve anything.<P>Now, I amazingly managed to get a stable picture yesterday for about ten seconds, but that was when tuning on the "clear picture with bad sound".<P><BR>What I would like to know is how I can check whether all those IF transformers are correctly set.<P><BR>I noticed that the 25L6 tube appears weak. It debits 30mA instead of 42mA so I'll have to find another good one. Since this tube drives the EHT transformer, I don't see why it should generate the "echo" effect on the video signal I can see on the grid of the Sync Separator.<P><BR>Any clues ?<P><BR>Thanks,<P>David Winter<P>------------------<BR>
