Question about Sony KDS-R60XBR1 60" Projection HDTV

1 Answer

My Sony KDS-R60XBR1 60 inch HDTV came on for a few min then shut down itself, and the power/standby led blinks in a 7 times mode (7 times then 7times then 7 times ... ). I read thru the fixes on this site (a fantastic site by the way). All fixes only mentioned 3, 4, 5 times modes. Can anybody share any knowledge on what's the root cause for 7 times mode? Thanks very much!

    Ok. Thanks very much. Who do you recommend for me to contact for the fix (sounds a little too complicated for myself to fix)? Is Sony local Authorized Service Center a reliable resource? Appreciate your help!

Hi,
7 blinks is an error code for "Audio Error" upon self check of the unit. It will not power up and will repeat the symptoms unless the faulty parts are isolated. This was caused by short-circuit of Audio power line in the K board. Faulty parts are the following :
1. PS3001 - Open fuse in K board.
2. IC3005 - shorted 12vdc line regulator IC.
You must replaced this two parts so that the unit will back to normal operation again.
If you don't have necessary tools and can't troubleshoot the unit yourself, I would advice you to look for a qualified TV technician to isolate and replaced this parts.
Also, you may replaced the entire K board for your convenient, click this LINK to place your order online. Board replacement has no soldering required, just pull-out the connectors from the defective board and put in the new board.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

    Sorry, I will correct myself...

    IC3005 is a Digital Power Amplifier IC and not a regulator IC...

    Yes, and I will recommend you to send the unit to them if you can't troubleshoot the unit yourself. Another option, if you can find friends that can replaced the K board, that will be fine also. You will save $200-$300 for service fee. But if it is not possible, sending it in is the best decision.



    Also, check if your unit is still under warranty period, avail it because the manufacturer will fix it for free.



    Hope I helped you.

Ok i have consulted the shops service manual on that sony model.A blinking led of 7 times is and indication that your audio cuircitry has blown. or shorted. most likely the audio amplifer ic. ic number 3005 on the K cuircit board. Specifically the audio power supply line has become shorted. most likely it would need replaced along with its assocated fuse ps3001

I have a Sony KDS-R50XBR1 that has no picture. When I turn on the TV, the green Power/Standby LED light blinks for about 30 seconds, then turns red and blinks five times. The Power/Standby LED repeats...


  • 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.

My KDS-R50XBR1 will power on with picture for approx 1 second with the power light in green, then shut down automatically and the lamp light blinks 4 times. Is this a bad lamp only? Thanks! Mike A.

I have a sony kds-r50xbr1 and the problem is that it takes about 1 min to turn on and the screen appears for a bout 1-2 sec and then shuts off to a black screen where the power/standby blinks continuously...


Its time to replace lamp in this tv because existing lamp has reached to end of its working life span and causing problem. If lamp got broken, you will see lamp light lit on tv front but weaker lamp cause above symptoms.
Lamp replacement procedure is easy and written in user manual.
Buy Sony original lamp for good and bright picture in tv.
Thanks.

Sony kds-r50xbr1 turns itself off and then green light blinks 52


I too have a Sony KDS-R60XBR1 tv and the issue that you are experiencing is due to one of your fans in the rear of the tv is not working.  The tv automatically shuts off in protective mode.  Make sure the POWER/STANDBY light is blinking and not the lamp light below it.  Is the power/standby blinking 4 times in red? If, yes then its a fan that needs to be replaced.  If its the lamp light blinking then you need to replace the lamp.  The lamp is easy to replace by ordering the lamp either from Sony for $250 or find it cheaper for approx. $150 from other DLP sources and replace youself by following your manual.  I hope this helps you.
