dtvpal dvr Freezing Repair
This thread has been very beneficial to me all the way back to 2009! (5yr pal owner) When I have a question about our ol' pal I come here. So I thought I'd post a problem my unit just recently experienced (it's similar to what others have experienced).
Audio & Video freezes randomly and pal becomes unresponsive. Have to pull plug and reboot (don't necessarily have to be using remote to cause freezing). This happened on both hdmi and component outputs, the only difference being that the hdmi screen image would blink (black screen to picture over and over) whereas the component video image would be a still frozen image. This started out happening maybe once a week then every few days then every day until ultimately happening roughly every hour or so (pretty much unwatchable).
Attempted Fixes that Failed:
1.Hard drive reformat
2. Factory settings reset
3. Anything else you could think of that didn't involve disassembly lol!
Proper Repair Made:
After disassembling the pal to free up both circuit boards I found 2 bulging capacitors on the GREEN MAIN BOARD (not power supply). One bad cap was underneath the square shiny metal top (upper rh corner in pic#2) just like someone else in this thread experienced. The other one was a larger size cap close to one of the board edges (pic#1). I was able to find a tv repair man willing to replace the capacitors without guarantee of fixing the unit. I agreed and his charge was only $25!
The pal has been in use for 3 days now running quite a bit for testing and I've experienced no freezing at all, no reboots, nothing. So it's looking like problem is fixed, however, I will report if problems return.
Thanks to this thread/forum (especially hawk69) for posting problems with your own units because I have no electronic experience and wouldn't know where to begin troubleshooting. Without help my dvr would be in the trash and I would be out $250 instead of $25 for a new ota dvr.
