I could still make out 68 over 2kv on the burnt capacitor. Replaced with a 680 pf 2kv that I bought at a local TV repair shop. works great.

Pressing the volume up and volume

SOURCE: TV seems to be in some kind of sales demo mode

To disable the Demo mode, perform the following:

  1. Turn GA_googleFillSlot("TL-IMU-Article"); on the TV.
  2. Simultaneously hold down the Vol+ and Vol- buttons on the front of the TV. Do not use the remote control.
  3. Hold for about 6 seconds
  4. Certain model TVs may turn off, others will not. But in either case, the Demo mode should be disabled.

Television won't turn on


Sounds like a power supply problem, you'll have to take it to a repair shop to fix that unless you know electronics. Good luck.
