Sony bvw300 humidity error - Sony Betacam SP Small Videocassette 30 Minutes Digital Betacam SP Tape

hi
1 has printer room humidity increased ?
2 was paper stored in a more humid room ( can absorb in a few seconds ?
3 was aither in 1 or 2 in humidity above 65 %?

That depends on whether you have moved to a place that has high humidity Electronic items are designed differently for different countries. Eg a TV for Australian conditions will be affected if it is moved to Singapore.

Otherwise its should be ok.


Please rate my help++++Thanks for using FIXYA

Hello :
Shorted humidity sensor, will occur if humidity sensor is detected as being shorted continuously over 5 seconds you need to replace humidity sensor .
good luck .
please rate !

it is an error code for the humidity sensor (dew)
try disconnect battery and pwr pack
for 60 sec and try it back
if its not work you may need service to fix it.

it is showing humidity error... keep camera in a dry open place for around one hour and check again

Open humidity sensor, will occur if humidity sensor is detected as being open continuously over 5 seconds Replace humidity sensor

Since the TV is still receiving power, the problem is going to be with the TV's mainboard.  After you unplugged the TV and plugged it back in, you said the power light went out again, so I assume the standby light wasn't flashing again?  The flashing standby light is indicating an error code so my suggestion is to contact Sony for service options regardless if there is a warranty or not because service is the only solution to this situation.  Don't forget to provide them the error code or 4 flashes repeating.

For me, the alcohol sensor cleaning didn't work. I did some research on how the sensor works and it turns out the black stuff is conductive in low humidity and resistive in high humidity. That means the circuit need to be cloed to work,, cleaning off the black substrate would only open the circuit furthur, I cant understand why removing the black substrate is working for some people. After cleaning it to no avail, I tried bypassing (shorting) it. To test it I just took an ordinary pencil and filled in some conductive carbon where the black square was. And it worked. I could have bypassed the sensor by shorting the 2 solder contacts, but to reach it I would have to take it all apart. I'll make the bypass permanent when I have a day free.

The error C31:98 it means Mechanical position fault..here u have to check the adjustment of position and phase Gear

Its a possibility that the sensor could be bad but I'll bet that its a small surface mounted capacitor thats bad. These are common for the caps to go bad, and when they do start to leak, the camcorder should be taken into the shop asap, AS THE LONGER YOU WAIT THE MORE DAMAGE the Capacitors will cause, as they eat up the tiny traces on the board and then the board has to be replaced. Good Luck
