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.

Turn on my Sony FD Trinitron WEGA KV-32HS510 32" TV, you hear a click, and then it blinks 3 times pauses and repeats.

Three blinks - 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. This is the fault with 3 blinks. If you wish to get more, check the site linked here. Pull up previous posts, either by brand search, or view it in Mosaic / Timeslide / Flipcard option.

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
