Question about Toshiba MW30G71 30 in. TV/VCR/DVD Combo

Power light comes on, followed by a high pitched whine

The TV will turn on, but I can only hear a high pitched whine, nothing actually shows up on the screen at all. This started last night when I turned the set off. Is thing going to have to go in for repair? I'm leaving it unplugged while I'm at work today.

Same problem. TV powers up but no picture or sound, just a high-pitched whine. Mechanical parts (VHS drawer and DVD tray) both work fine.

Hi, If after trying the TV again later and problem persist, repairs are in order. A high pitched whine is an indication of a fault at the horizontal section of your TV. The horizontal provides the high voltage for the picture tube. Your best bet maybe to seek the services of a qualified professional TV repairman since this involves component level repair, soldering/desoldering, use of soldering iron and VOM (testers) and knowledge of circuitry. Good luck and kind regards.

This tv is under five years old?Yes,it is worth fixing.Over five,i would compare the prices for a new LCD tv and the quote priced from the Tv Tech.for the old tv.This tv have high voltage problems around the Deflection circuitries area.Could be any things burn in this area.The high pitched whine sound,i'm sure it is from the FBT-the high voltages flyback transformer,high voltages current have no where to go.Must hire a tv tech. to troubleshoots and replace parts on the Deflection circuitries area.Also the FBT could be dead too,because HV Current bounces back forth and have no where else to go.The prices to troubleshoot unknown problems is about $400 bucks and plus cost of replacement of parts.

High pitched whine/sometimes TV won't turn on

The power supply on this model will whine when it is shorted or overloaded - the set would have to be brought in to determine exact cause.

No picture or auido.

Place your ear near the back of the tv and have someone turn the unit on. If the following occur :

a.) If you hear a high pitched whining sound and the fan trying to start but the unit fails to start and goes all quiet it could be a bulb issue. (see owners manual for trouble shooting code of blinking power light in front of tv)

b.) you hear nothing. It may be that the power supply for the unit has failed or its fail safe fuse has tripped. ( call tech this one needs a pro to sort out )

c.) seems like its trying to restart itself but does not quite make it. ( its a bulb issue check owners manual )
