Greetings Victor, I will be curious, what problem did you have with replacing a tantalum with an electrolytic? In my experience in a vertical operation, there are very few verticals that use tantalum, I have seen the same integrated in different chassis, some with tantalum and others with electrolytic
It was a problem in vertical synchronism, replace with electrolytic of the same value, it was not
I solved the client's TV by placing the tantalum of another TV of my property, then to solve my TV I had to get another card
On vertical exit with LA7837, some tvs came with a tantalum and other models in the same location an electrolytic
In those cases it can be replaced
