PSE-324 Power Supply Board Repair for Sony 32TS2U Plasma TV

Warning

SERIOUS INJURY OR DEATH COULD RESULT FROM THE IMPROPER REPAIR OR SERVICE OF THE TV.
ALL WORKS MUST ONLY BE DONE BY AN QUALIFIED TECHNICIAN.

The work procedures are important for ensuring the safety of the product and the servicing work. Be sure to follow these instructions.

Before starting the work, secure a sufficient working space.

At all times other than when checking the product, be sure to turn OFF the main POWER switch and disconnect the power cable from the power source of the display during servicing.

To prevent electric shock and breakage of PC board, start the servicing work at least 10 minute after the main power has been turned off. Especially when installing and removing the power supply PC board or the SUS PC board in which high voltages are applied, start servicing at least 20 minutes after the main power has been turned off.

When handling the circuit PC board, be sure to remove static electricity from your body before handling the circuit PC board.

Be sure to handle the circuit PC board by holding the large parts as the heat sink or transformer. Failure to observe this precaution may result in the occurrence of an abnormality in the soldered areas.

Do not stack the circuit PC boards. Failure to observe this precaution may result in problems resulting from scratches on the parts, the deformation of parts, and short-circuits due to residual electric charge.

Perform a safety check when servicing is completed. Verify that the peripherals of the serviced points have not undergone any deterioration during servicing. Also verify that the screws, parts and cables removed for servicing purposes have all been returned to their proper locations in accordance with the original setup.

Packing

Obviously circuit boards are relatively fragile, and poor packing can result in a board that is damaged beyond repair.

To properly pack the board, wrap it in three layers of the bubble wrap and place into a snug fitting box, or use more bubble wrap to fill the box so the boards do not bang around in transit. Some courier companies use a conveyor belt system that drops boxes about three feet.

For this board you can use USPS Priority Mail Flat Rate Medium Box. In that case the shipping wherever in USA will cost about $12 plus insurance and confirmation charge.
