I just finished repairing one of those sets (CK3527) and I replaced about 25 capacitors on the deflection board, signal board, and CRT board combined. If you see any black spots on the solder side of the board, you might have a capacitor at that location which is leaking. The cap closest to the vertical output IC was so bad that one leg stayed on the board when I removed the cap. Have you gone over and replaced the caps? Sorry I forgot to measure the temperature of the heat sinks in this set, but I did measure the temps in a 27" model (CS2723) of a similar chassis a few days ago. After that set ran a couple of hours, I read the following: HOT heatsink: 46°C (did the degrees sign appear between the 46 and the C ?) Regulator STRS5141G: 58°C Vertical IC, LA7838: 46°C My temperature meter only displays in Celcius. For displaying the "degrees sign", you could try holding down the ALT key, then while still holding the ALT key, press 0176 on the numeric keypad. Then release the ALT key. Depending on the font you are using, you will probably see the degrees sign appear in your document. You can get many other characters also, such as the Ohms sign, a heart, diamond, clubs, etc. The easiest way to do these is to use the Character Map built into Windows (if installed during Windows setup). On Win 2000, Character Map is available by clicking on START\ PROGRAMS\ ACCESSORIES\ SYSTEM TOOLS\CHARACTER MAP. kevinstv wrote: > > Would adding some more metal to the heat sink for this vertical IC allow the > IC to run cooler and therefore last longer?
