Hi all
Years ago electrolytic failures on LT rails were something of a rarity.But now it seems that every lcd tv PSU more than 18 months old is littered with domed caps.Is this down to the proximity of the rear cover causing insufficient airflow or insufficient heatsinking again for rear cover manufacturing purposes?
With the crt tv's generally the high voltage caps(HT,200v rail etc) or SMPS start-up gave the problems.
Why now do we carry a bucket load of 1000uf 25v caps with us wherever we go?The caps we replace are invariably 105 c as well but LT caps way back were usually 85 c and happy.
Has anyone else given any thought to this?
Whatever the reason,here's hoping the manufacturers don't correct the problem.
