In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.

HiIhave a Samsung LA32B350F1 LCDTCgetsoffafterclearlightboards

You might want to call Samsung with the model number as I remember seeing a notice for certain models that have this issue---a jumper plug needs in those sets to be removed that is located on the power board.

I have the same model, try to enter the service menu following these steps: - Power off the TV through the remote. - Press this sequence of keys: Info, Menu, Mute, Power on. The service menu will appear.
In the service menu, disable the hotel menu. If it is enabled may be the cause of your problems.
NOTE: change options in the service menu at your own risk.
See you.

You have a lamp driver error that can be and most likely is faulty and has to be replaced,Also i would not recommend you putting a bigger lamp unless the part numbers are the same to the lamp you are replacing.Moreover most of sony's error codes are the same from crt to lamp tv set like your lcd model tv set, the same concept was used to built your lcd tv set just with different features.

I am unable to find in your statement about which brand or type of motherboard is used. One thing i come to know your using service mode kit. knowing in your statement your are a technical person. My simple idea is first you set the TV in standby mode using remote. Then in FBT reduce the screen control minimum position, the release standby. Now the tv is oscillated, now slightly increase screen control till get maximum video and zero retrace line set in position. Even no improvement give me clear picture of brand and microprocessor ic etc. there is a chances to solve by having the above details.
