I get a picture for around 30 seconds and then black and Grey Horz bands throughout the screen .I have been told possibility problem on FE board?
They for the most part only sell boards for these--the error codes can be misleading in many ways---suggest you Google the model number and see what boards are in it and what they cost to decide if set is worth a shop repair or not.

I am pretty sure this is a Back Light failure or a bad Ballast. If it is the only fix is to replace the LCD Panel. I would contact Sony at 1800-222-Sony and see if the could help you with repairs and also to get a Factory Service Facility near you to confirm the problem.
Hope this helps,

you either have a power supply problem or a inverter bd problem
id suspect the inverter board
its the panel that supply the power to the cold lamps that back light your lcd screen
There is a high possibility that the components over a period of heating and cooling, tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs or poor performance. The best way to check for loose connections is to tap lightly when the set is powered on, if there is change while tapping then it seems that there are DRY solder joints. Remove main plug, the covers - with caution of high voltage, check for dry joints, and use a good soldering iron to solder all suspected points. Sometimes the fault occurs when the set warms up; if so you can simulate the heat using a hair dryer on the suspected areas, try with the power supply, distribution, Processor controller, driver controllers on the A/V related sections. Also the use a FREEZE-IT spray can simulate the components to cool and show up the fault. It can also be related to WEAK ELECTROLYTIC capacitors as the value can reduce in time. Based on the above method you must be able to locate the area of fault and solder the sections.
