From feedback we have received, there can be a fault with Samsung LE40R73BD and Samsung LE40R74BD LCD TV's concerning the turning on of the TV.

This normally appears after approximately 22 months of use.

Symptoms: The LE40R73BD or LE40R74BD makes a clicking noise when power is connected. The standby light may flash while the TV clicks. No picture appears from 5 to 30 minutes.

At the outset this pattern may persist for a short period, with the TV eventually turning on. However, it is likely that eventually the TV will not turn on at all.

The problem relates to half a dozen components on the power supply circuit board.

A brand new replacement Samsung PSU for the LE40R73BD or Samsung LE40R74BD models will cost in the region of £160. A TV repair shop may charge slightly less to mend the original board.

What we are offering is the chance for you to fix your own TV.

HOW DIFFICULT? The PSU board is quite large with the individual components nicely spread out. Only six small components need to be replaced. If you are able to use a soldering iron then the task can be completed in minutes. This task is very simple and if you have some very basic skills then should save a lot of money over the alternative solutions. If you can't use a soldering iron, then perhaps you can find a friend who can?

Whats in the kit? We supply detailed instructions (including colour step-by-step photo's) of how to remove the back of the TV (just a dozen screws), how to unplug and remove the power supply circuit board, and which components require changing. We supply the replacement components in the kit. A length of solder and desolder braid are also included.

Soldering irons are available from many hardware shops, or Maplins for example, for just a few pounds.

Safety: Always ensure the power cord is unplugged from a TV before starting any work, and do not reconnect until the TV case is fully screwed back together. If in doubt of your ability, obtain the assistance of a professional.

Please note that a refund is not available on this item, as part of the product is providing instructions on the repair process.
