LCD panel turns off after 2-3 minutes; sound remains alright

Hi,

We have a Sony Bravia smart TV Product no: (kdl50w800c). The issue is that the LCD panel turns off (More like fades off in 3-4 seconds) after couple of minutes of turning it on; but the sound remains alright. Tried fixes:

  • 60 seconds unplug and plug reset
  • Factory reset
  • Cleaning the dust off the board and testing

No luck yet. Any help is appreciated.

Thanks in advance.

Shawn.

Hi @shawnfernando

If the standby LED doesn't start to blink when the problem occurs, (see p.10 of the service manual if it does), try running the self diagnostic screen display test as shown on p.12 of the service manual and check what it shows.
