Sony WEGA KE-P42XS1 will not boot up
PLEASE HELP !!
I have a Sony WEGA plasma KE-P42XS1 and I entered the test mode by pressing the keys on the remote: {display} - [5] - {up vol} - {TV}. (The intent was to fix a problem with the horizontal position of the picture, but I never got that far.) I got some big characters with Tnnn on the upper right. The last thing I did was hit the sequence {display} - [5] - {DN vol} - {TV} and nothing happened. I decided to stop everything and power down the TV and power up. I was horrified to discover that the TV would not initialise. I only had one power light and no other lights (stdby was off). I disconnected the power to the TV, waited a few minutes, reconnected power and tried to turn it on, but all I got was the one glowing power LED as before. TV was dark. No other LEDs were on. Remote did and does nothing to the TV (remote itself is working). I even cycled the power switch on the right side of the set with no results other than the power led cycling on and off as I pressed the power switch on and off. My TV is not under warranty. I am an electronics technician and I have the service manual, but it says nothing about the service codes. I got that info from another forum. Now I know why the service manual said nothing about the codes. I figure that the next thing I can try is perform a firmware or software update, but I need the firmware file and the instructions or service bulletin that goes with it. Can anyone help me ? (short of suggesting to take it to an authorized Sony service center) Please advise. |
