Model WS55819, shut off and won't turn back on. The first few times I tried to turn it on, the indicator light came on and went off after a few seconds. Now there is nothing. I removed the panel from the back and checked power in, which is good.

Hi,
Most common problem in WS-55819 is failure of convergence output chips and blown pico fuses in power supply section.
You need to read out error code in tv, procedure is as follows:
Pressing the front panel "INPUT" and "MENU" buttons at the same time, and holding for 5 seconds,
activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem has occurred since the last Initialization.
Note: The front panel buttons must used, NOT those on the Remote Control.
• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2 second.
• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
• The Error Code is repeated a total of 5 times.
Example: If the Error Code is "24", the LED will flash two times, pause, and then flash four
times.
Error codes detail:
The Error Code designations indicating a malfunction, or no malfunction, are listed below:
"12" ... indicates no error has occurred.
"21" ... X-Ray Protect circuit.
"22" ... Short Protect circuit.
"23" ... Horizontal Deflection failure.
"24" ... Vertical Deflection failure.
This way you can determine what section got problem in tv and causing problem.
Let me know if you need further info.
Thanks.
