Thank you for interesting my question.
Voltage and capacitance are the same 16v and 470microF.
Here is a photo of old one and same capacitors on pcb from old TV (what I call "polymer").
My Uni-T61 shows 40microF on old (that bulging) capacitor and about 450microF on replaced smd.
Unfortunately I don't have a new capacitor with the same capacictance and voltage, or same size. I have one new, but much bigger CapXon 470mF 35V 105"C Low ESR - I think he wouldnt fit in notch in heatsink.(
Find good radiodetails in my country - it is a big problem, aspecially fast and in my town, mostly cheap and creapy chineese jobbing... Used parts - most accessible.
Best manufacurer I have seen - Jamicon, CapXon (mostly), SAM, SAMWHA.
The brown electrolytic capacitor on a second photo - also have good conditions: 470mcF (450mcF tested) 105"C, but 35v and bigger size - maybe he will be better?
I will try find a new real polymer capacitor and replace as fast as I can.)
Also have another question about capacitors in aluminium shell - whether a short circuit if they come into contact with-each-other or other parts? I suspect this is wrong, but I have to ask.)
