(reverts to the standby light flashing when plug switched off and on again)

Hi John and RB
Set now up and running. It was a case of a corrupted eeprom. Thanks John for the info.
For anyone with the same problem the procedure is as follows.
On this model the eeprom in question is IC 1803 (24C256) 8 pin smd and is located on the underside of the main board near the common interface. The clock and data pins are pins 5 and 6 and are identifiable by the 100 ohm smd resistors connected to each of them. Fit a shorting link (on long wires) between the pins. Reassemble the chassis. Switch on and then remove the short. Bring the set out of standby. Now access the service mode as follows-
Using the remote control, switch to standby, press info, menu, mute and power. The set should start and display the service menu. Using scroll keys select item 8 and enter by scrolling right. Select "tuner" and set to auto. Revert to previous screen by pressing menu. Now scroll to "reset" and enter by scrolling right. The set will revert to standby. Power back on and tune in stations. Thanks again tv john for the information.
John.

I'm in this boat. I've tried ALOT of times. I get everything as described except for any kind of life in the screen. At no point (during the shorted startup, the normal startup or the service mode palaver ! ) does the backlight come on. Am I right in thinking, if I never see the backlight even attempt to come on I'm not going to get anywhere. I ask because I've get the feeling the service is mode is there but I can't see it. This TV has made me paranoid !

Hi,
Are you sure the inverter is supplied with the right voltage and attemps to start?If not, could be defective,unfortunately.Try to put close to a transformer a neon small bulb,when you power up the TV;if the bulb lights up for a while the inverter could be safe;if so,think about the micom!
Happy new year!Michael
