Question about Sony KP-61XBR48 61" Rear Projection Television

1 Answer

In response I do have the manual but I do not even know were to start. In another post you told someone to check transsistor T603 and Resistor R672. Do you think that is a good start for me and could you tell me what board they are on to find them. And is this usually an expensive problem to fix. I hope I don't have to spend too much but I don't want to scrap the TV either.

Those are on the power supply board. Usually its a minor part that is causing the set to shutdown when you repair it at component level. Circuit board replacement is where you can find it getting expensive. just take your time and famillarise yourself with the manual and take one of the start up voltages at a time and verify that they are correct. If not then back up on that circuit checking the components outlined in the schematics that feed that component. You will find it. just be careful around the higher voltages. go slow and be safe with it.

TV turns off and standby light blinks. Blinks 3 times, pauses, blinks again 3 times.


Hi there,
Three blinks means technically 'B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.'
After a little more research i found this comment:

"Guys I have found the problem. (referring to T603 and R672) I have found mine anyway. When I replaced my projection lamp, I failed to push the lever all the way down, but this was not the problem, just something you need to be sure to check. The problem was the lamp door. This needs to be shut properly. I found another thread where a guy had tried the same thing. It worked. The door clicks hard at the end to set itself. This worked for me. Hope it helps you."

IMPORTANT: After you repair the unit, you MUST clear the values on this diagnostic screen. These codes do not reset themselves after the fault is corrected, so if you don't clear them, you'll be seeing "old" fault codes the next time you enter this screen. Clearing is done by going into the service mode (display, channel, 5, volume plus, then power ). Press 8 and Enter, which returns everything to the factory preset condition.


So my question is have you replaced the lamp?

Hope this helps

On the Sony FX43 100Hz 43-inch rear projection TV, three flashes indicates an Over Voltage Protection problem, occurring in one of the power supply circuits T603 or R672.

The fix will most likely cost more than the set is worth second-hand, I'm afraid.

Sony KP46WT520 blinks three times


They are on the main power supply board. Yes if you can solder and are careful around the high voltage items such as T60s you should be able to do the repairs easily. I would recomend a service manual however. If you would like a link to get the service manual and parts let me know
