i have a sanyo television that is under a year old (lost waranty) model DS25204, and it was turned off one day and wont turn back on. if it is plugged in it makes a high pitch noise as if it were on and the back of the tv gets warm. what is wrong and how much would it cost to repair?
the high pitch noise may be happened due to the fbt( flyback transformer) leakage, this fbt supply about 30KV to crt, please extra careful, go to survice centre tell them about this

If there's a high pitched noise, then the power supply is probably running ok but under excessive load from a fault in the line output circuit. Usually a sign of a short circuit line output transistor (inexpensive) or line output transformer (expensive). More common is transistor though. Contact manufacturer re warranty, they should have records to verify date of manufacture against it's serial number and date of sale to the dealer, irrespective of warranty card and dealer should have record of sale to you. Really shouldn't be a problem, don't let them fob you off.
