There seems to be a pattern of failure of many capacitors in this chassis series. Problems that relate to these failures are the failure to complete boot cycle (timer LED blinks continuously) and a number of startup issues including lamps not starting or shutting down. The most obvious manifestation of the failures are swollen or vented caps. We have seen sets with a dozen or more swollen capacitors. Many more are often on the way to failing, demonstrating low capacitance, high dielectric absorbtion, high ESR, or d.c. leakage. These caps are the conventional radial polar electrolytics made by Jamicon.
Additionally, some of the problems with lines in the picture may be due to problems with surface mount capacitors. We have found caps on the DM that appear to be thermally sensitive, and have high ESR.
One can speculate as to the reason for these failures, but it seems certain that all of the radial polar electrolytics made by Jamicon are suspect. Virtually all that test are marginal or test bad, even if they are not swelling. I recommend replacing all of the following caps.
The most reliable brand and supplier at the best prices that I have found seems to be the Panasonic caps from Digi-Key. Use the longest life, lowest impedance, 105 degree caps available in the right size and value.
