Have a Sony TV modelKDS-R50XBR1 and after changing
Have a Sony TV model KDS-R50XBR1 and after changing lamp, started to see yellowish background . In web site some had mentioned that was caused by Optical block and since my tv is very old, I would like to attempt to fix myself. Can you give me part number for the optical block and if possible recommended places to get them and the cost? I like this tv and its technology. Thanks.

Make sure the lamp is OK first. It needs to seated correctly, if the tv is blinking 3 times it means one of the switches within the lamp tunnel is not working. Make sure the lamp door is seated correctly.
the lamp is located if you are standing in front of the tv, on thr right hand side behind the screen on the side of the tv there is a thumb screw that you have to remove with a flat head screwdriver then you can remove the door and see the lamp inside.
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.
