Question about Sony KDSR50XBR1 50" Projection HDTV
My KDSR50XBR1 intermittently will have the sound and picture disappear, the green standby light blinks 52 times and the picture and sound return. No set schedule (does not appear to be a function of how long the TV has been operating and may go days without occurring). Any ideas?
52 times? Sorry for laughing...
I would bet it actually flashed 4 times and continued to cycle four times...lol...
If that is the case, check it again to be sure...
If so, here is a very easy fix, created by yours truly...
Ok, I think I have the answer for the BIG FAN failure. I recently did a similar fix on the spindle of an xbox 360 and it is identicle. Ok, this is an EXTREMELY EASY FIX...
Open the back of the tv, locate the large fan (on the lower left on the back of the set.) unscrew the screen and remove the fan.
Once the fan is removed, you will see the side with the model number and the other side is totally open.
On the open side, pull...
The fan will come off, into your hand, it is only held by magnets...
You will notice a spindle on the fan and the other side has the magnets and the hole where the spindle came from (this is the fan motor).
Clean both the spindle and the hole (motor) with a q-tip. The hole is smaller than the q-tip, but do the best you can to remove the old lubricant.
Get a bit of WD40 and lubricate the spindle and spray a touch in the hole.
Put them together, reconnect your fan, test it on startup and thank me...lol...
HOPE THIS HELPS!!!! IT WORKS, TRUST ME...

Five blinks - AKB
circuit (automatic kine bias), the timer/standby indicator blinks
for about 30 seconds then goes to the self-diagnosis function.
Something is wrong with the video. Check video out, Q705, 732, 761
and other components on the C board, also check Q218, 219, 220 on
the A board. In addition, unit could be in IK blanking, try turning
up screen A2 slightly.
