SYMPTOM
D
ead or stuck in standby.
All Sharp LCD TV sets have a Lamp Error detection circuit which will return the LCD
TV to stand-by if a fault is detected, the fault is logged by the lamp error counter which
will render the LCD TV inoperative if it the error count reaches 5.
To enable fault finding the lamp error detection circuit is ignored when service mode is
activated. Service mode activation is detailed in the relevant service manual.
After the fault has been diagnosed and repaired the lamp error counter must be reset
to  “0”  before  normal  functionality  is  restored,  again  this  is  detailed  in  the  relevant
service manual.
CAUSE
Possible causes of this symptom are:
  Inverter circuit failure (switching transistors)
  Lamp failure (no or low output)
  Poor or loose connectors, fuse holders  (lamps or inverter board).
  Dry joints (power supply or inverter board).
  Trapped or chaffed cables to lamps.
  Power feed to lamp inverter circuit.
