The error code of 4 blinks indicate a fan problem.the fan is slowing or internitantly stoping. the fan is stallling. or the fans not getting power. Always rember anything that moves will eventally stop. this fan is on all the time. also there more than one fan. Listen closely to hear the fan. The fan is not difficult or exspensive repair.
Hi, 4 times blinking light indicates problem with exhaust fan in KDS-R50XBR1 and possible causes are as follows: -Fan 1-4 power is not supplied. (ASU board) -Fan connector is not attached securely. -Fan caught wires or harnesses. Please check exhaust fan in tv, it is located at lower right of tv looking at rear of tv. Thanks.
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.
Just replace its Lamp and procedure is written in user manual of KDS-R50XBR1 F93087600
XL-5100 LAMP BLOCK Lamp is available in Sony Accessories and price is $250 Always buy Sony original lamp for good picture in TV and avoid aftermarket / cheap lamps that can cause damage of TV circuits. Click Sony Support to download Instruction Manual copy, if you want it.
If you are positive that the fan is still running and that it isn't an over heating issue, I would venture to say you need a new dlp lamp. Your model uses a Sony XL 5100 dlp lamp. You can grab one over at DLPLamps.com.
