Hi all,
I am having a problem with my Poloroid TDA - 03211C with Power Board IPOS 150 Ver. 1.8. I get a red led on the front, but it doesn't power on. Upon taking off the back to get voltages, I noticed that the caps at EC17 and EC 18 were blown. I ordered new caps from Digakey and also order new FET's at Q16 and Q17 and replaced all of them. I replaced the filter cap too with a new high temp Panasonic. After getting everythig back together, here are the voltages that I have from the pins....just nothing is powering on:
STB= 4.83
5STB= 5.13
5V=5.13
12V=11.78
20V= 23.98v
Also, the filter cap, when the main board and inverter is attached to the power board, it swells to 400V and holds steady on the reading. When I disconnect everything except the power, the filter caps is steady at 167volts. I have attached some pics. Any ideas or questions to help me along would be welcome!!
