I have a TH50PX60U with the red light flashing 10 times. I went through the diagnostic flow chart to where it said replace the PA and DG boards. I replaced both and still have the 10 flashing lights.

I got a Sony Bravia KDL-40WL135. Blank screen. There's two LED lights: red standby and green power light.
When I turn on the TV, green led comes on, then after about 30 seconds red led blinks once, then green resumes. The green led stays solid. I think that's a SONY error code, I tried to look it up but can't find anything useful.
I have replaced the power supply, AU board, backlight inverter, logical board, and the second power supply board.
Any suggestions? I haven't checked the t-con bo

I think I shorted out the power supply board on my Onkyo HT-R667. I was replacing some the capacitors to repair a hdmi switching issue. I was testing the repair with the top cover off. While it was powered on I accidentally touched the metal top to the top of the power supply board CMKM-P3X. There was a spark and the unit turned off. It won't turn back on. No lights. Can it be fixed or can I purchase a replacement board if this is even the issue. Thanks

Fixya tv I have a Samsung LCD TV. Model Number LN40B530P7FXZA. In January this year my TV picture went out and only had sound. I replace the power supply board and all was well. Well the same thing happen again but this time one of the fuses on the board has blown. I replaced the fuse and as soon as I plugged in the power cord it blew. I did this twice. Should I get another board or is it something else? Thanks.
It sounds that there should be a dead short circuit in the power supply board's circuit. If you are not familiar with\012electronics, do not attempt to repair. \012Whether you suffer fatal electric\012shock. Instead, conta ...
