Question about Televison & Video
I have an almost new Polaroid DVR model DRA-01601A. Yesterday it worked fine the next day it wont even power up. I hear the fan turning in the back when connected to the outlet but it does not turn on.
99.9 % of the times its the capacitor which is blown. I had spent few weeks to investigate on this and ultimately found this solution. Till date I have replace two capacitors. To determine which capacitor is gone, Check on the flat silver surface of capacitor. If its not 100% flat it means its gone and you need replacement. Pl. check my attached file to understand on details of inside configuration.
Hopefully it works for you.
I am not able to upload pdf which I have created. Pl. contact me via email to get pdf file

Replaced four capacitors on the power supply circuit board which were clearly bubbled up. Found corrosion under two of them. Just replace a pair of 1000uF 16V caps with 1000uF 25V caps (same value but higher voltage rating) and two 2200uF 10V caps with two 2200uF 25 V caps. Make sure you're putting the negative side of the electrolytic capacitors in their proper spots. (if you reverse even one of them you risk blowing up the whole power-supply). This is also a good time to replace that noisy cooling fan with something comparable. not sure of the size, but it s model RA-04 01LS12 which is a DC 12v fan with 0.07A current draw from Apple Electronics or RApple. Good luck!

I believe I found the problem but just will not be able to fix it unless I can find a new main board cheap. It would appear power is getting to the main board but will not power up.

We found that our problem may have been heat related (the unit might have been overheating) We reported our issue to Polaroid and they were very willing to replace the unit (as long as we paid for shipping the unit back, of course) However, after reporting the problem and setting up the exchange, we spent some time burning our videos to DVD prior to returning the unit, during which we increased airflow to the unit. During this time we experienced almost no failures, leading us to believe that it may be a thermal issue. In the end, we're using our new unit from Polaroid, so far with no problems.

Mine have severe problems, I removed the front panel and front board and replugged in all the connectors, and when put back together it worked. I think I had a shorted trace on the front panel to one of the screws (or maybe the force was just with me) anyway thats my story

These units are famous for capasitors popping in the power supplies.
