Sanyo TV LCD 32 inch about 3 years old. No

If a 4 year old 32 inch set likely cheaper to replace than repair it assuming parts are even still available.

Hello
The power supply regulator board to your set has the fault. If you try to open the set, or try to repair it by yourself, the warranty will void. The set must have warranty as it is new. Why do you spend for it? Just contact the nearest authorised service center for Sceptre. the components in this set will be very hard to get from open electronic spare part market, and will costly too.

Check the power supply could be a simply a capatitor bad .

Sanyo is cheaply made TV, but then again, most LCD TV last about 2~3 years before breaking down.
You need to check out the power supply and the inverter board.
