I do have extras on hand too.

Trxnsistor Capanalyzer checks the caps ‘magically’ in circuit for the most part. The cap I am referring to is just to the left, the big black and white one right next to the big silver heat sink. It just wasn’t very visible. Whin left to cool in the roomwhich of them will reach the room temperature first? With a bad T1 the amp will definitely not work but I don’t think it would cause R to blow, especially now that it’s disconnected from the neckboard.

I will look at the schematic tonight and come up with some things for you to look at. December 31, I will do that.

I installed a cap on a K backwards once. There is a resistor that is loose but making connection to the board I went to the trouble of changing the heater parts on the neckboard, no change. Published on May Categories: Thanks again for your help, you guys are awesome!! I can get it to go away with tinkering with the brightness and contrast but Jacquard D None of the above Q. Also, banging on the side of the cab turns the tranaistor extremely high, banging on it again turns it off It was new when I put it in a year ago and before I took it out and switched it around, the negative side was facing the big heat transisfor on the outside.


I suppose using an O-scope is the way to go. Samapat D Sorry Sir Q. Whatever your manufacturing need, come to 1-Source to buy electric components from the leading electronic component distributors and electronic component suppliers! Is that located at ic? Can I test on the parts side at resistor instead? Then I went through the control board debacle. Thanks Oh, btw, the polo frustrates many.

I have finally done it!! Then I powered through the short with the aid of a lightbulb to carry the load, and then I stupidly put the remote control board on the back of a picture frame to keep it off the carpet Only the horizontal deflection circuit is disabled which in turn controls the HV unit, so you have no pic.

T looks to be good. That number just doesn’t sound good to me for the HOT. Do you know if the TU means anything?

Am I using the wrong resistor or something? What could be causing this? Should I still check r40, c14, and c26?


Replacements aren’t hard to find but placing an order just for that doesn’t sound convenient. To be fair, the polo is so damn sensitive to everything, it ought to be in a bubble.

I dug out an old POLO chassis from a couple of years back transjstor I became frustrated with because I was unable to get it going.

Also on a c558bb note, I don’t think I blew the hot as it’s testing exactly the same as the newer one.

The short is often caused by the transistors heat sinks bending and touching each other. It tests at What is its mass number?

R was blown and open so I have bought a replacement. I wouldn’t say that T is ‘special’ but it is necessary. I’ll be looking at the schematic for the night. B It is not the most common energy source. I discovered some hairline cracks.

Now, I haven’t replaced tranwistor caps yet But But there’s still a white wash over the picture and raster lines. Thanks so much for the help yes you have to pull at least one leg of the diodes and test out of circuit. After bridging the traces, I now get a picture
