If you open it up, you will find a little slime layer on the PCB under the buttons you use most. It will also be on the little carbon "buttons" glued to the rubber on the inside.Whats the solution to repairing faulty remote controls (for tv's, vcr's, etc)? It seems after a few years of use the most frequently pressed buttons don't seem to function too well and need to be pressed really hard to get them to work. Is there a fix for this?
This may not be exactly what you had in mind but have a look **broken link removed**
Using pure Acetone is not a good idea, as sometimes it will partially dissolve the wrong carbon tracings or else harm the impregnated carbon rubber push buttons, and ruin the remote. What I found to work the best is pure Iso-prop alcohol using a swab or camel hair brush and then moderate air pressure to blow dry all remaining alcohol and any residuals off both surfaces. The cheaper remotes usually require more frequent cleaning as well. Better made remotes seldom have this problem! Keeping food and drinks away from them as well helps!
Well, I am currently watching a 32" trinitron I bought back in '96 and it still has the most perfect color picture I have ever seen (even better than many new TVs today), despite the fact I have used it an average of at least six hours a day over it's life. The perfect picture was a big deal because I used to service color TVs, and any color errors like convergence or purity really annoy me even though most people wouldn't notice them. This TV is the only one I have seen with near perfect convergence/purity all the way to the edges and corners so the picture-in-picture box in the corner is as sharp as the center of the screen. It also has a total of four video/audio inputs for accessories and every one has its own full set of control adjustments on color/brightness/contrast, etc so each VCR or video player looks perfectly adjusted. Again, a particular annoyance for me because I tuned color pictures and I like it when they are set just right. No other way to do that with three external units playing through one set.Sony doesn't make that great of a TV set to begin with - much less any of their other electronics as well - sorry - but it's true. Just because it had the name Trinitron attached to it didn't mean diddly as well.
