And I'm willing to bet that you rarely, if ever changed a (white) LOPTX in all the time, the only one that I ever recall replacing was for one ended focus. True. Never as far as I can remember. One of the most interesting things I encountered was when I was called to a local pub around 20 years ago as they said the TV pic was getting a bit dim. When I got there I was directed to the bar where there was a large black wooden box hanging from the ceiling and a projector screen on the wall. I climbed up on a table and found that the back of the box would slide off. I couldn't beleive my eyes when, inside I found a standard 14" TX9 TV. On the front of the box was a large cylinder containing a fresnel lens. I switched on and was greeted with a perfectly good, if a bit dim, picture projected onto the screen! It was showing MTV from an analogue satellite box as I remember. The sound was fed to speakers on the wall. The landlord told me that the arangement was made by a former customer who had since emigrated and that he usually just cleaned things up a bit when the picture deteriorated. I couldnt resist the challenge so I lifted the TV out of the box, sat it on the bar and took a closer look. The whole thing was thick in niccotine but the interesting thing was that the connections to the scan coils had been reversed so the picture was upside down and back to front. This made it project the right way round! I went out and bought a large can of Mister Sheen and set to. I polished the screen, dismantled the lens and polished every surface and then scrubbed the screen on the wall. As with all TX9's the contrast, brightness and focus were stunning, which is probably why the inventor chose this type of set. Once I had assembled the whole thing again, I switched on and was met with quite a spectacular picture, bright enough to watch, even with the curtains open and about 5ft across. The only adjustments to make were to move the lens for focus and move the TV within the box to get the best position. I kept the arrangement running for a year or two until the pub changed hands and the system was removed. I almost wished I had asked them if I could keep it but it would have ended up with all the other junk which I seem to collect. A clever idea, though. |

Talking of (projection) junk amassed from happier times, many years ago I had plans of using a modified Thorn 1500 B/W chassis (with 25 KV CTV multiplier) to make a more up to date projection receiver, another fine idea that never materialised! http://picasaweb.google.com/Anth230542/ProjectionOBXS?authkey=Gv1sRgCJuBjsrU9uTBYQ# |

In article en.co.uk,
Roderick Stewart wrote: Sony made a TV projector that was more or less this. Remember those Barco projectors with the three lenses, one for each colour? They just had three CRTs behind them. The Sony projector had just one lens in front of a standard Trinitron tube, slightly overdriven to produce a bright picture but basically the same tube they'd use in an ordinary TV. I've never seen one of those types of projection TVs that got even near a normal set in terms of lumens. Whereas a DLP type will exceed them. -- *You're just jealous because the voices only talk to me * Dave Plowman London SW To e-mail, change noise into sound. |

Not from memory but I did find this 'if' it is the GR2.4 chassis.. low field, TR7546 BC848B (SM).. TR7502 TR7503.. R3503 (4R7).. you could also look for dry joints rear of scan coil panel, HTH. |
