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.

My Magnavox tv is about 5 years old. When we turn it on the screen is blank. A soft high pitched sound comes out of it. The green "on" light blinks on and off. Any ideas on what is happening and why it...

You have a bad eeprom. Very common problem for this TV. The replacement eeprom [location, IC002, on the Tv board] is dependent on which microprocessor [location, IC001, on the TV board] and which stereo decoder [IC 1001] are present on the board. See if IC002 has a color mark on it. red, yellow, green..etc. Or give me the numbers on the actual IC 001 and Ic1001. For example IC 001[ microprocessor] might beMCU A22V01-TO and IC 1001 [stereo decoder] MSP3440. Take this info to a TV tech if you cannot repair this TV yourself. Thanks for asking and give me a High Five of hands!

Shuts off

sounds like the high voltage transformer
or could be high voltage off the tubes.

not a good idea to keep this running as it will cause more damage, best to have service tech look at this since it's high voltage.

Be careful. This same problem burned a mark in the Blue crt on my pro730HD. Three months and the Service Tech and Pioneer have been unable to determine the cause (they claim). In the process they have blown two more crt's.

When your tv goes off, try turning it back on using the main power button instead of the remote. The button should be behind a flip-down strip below the screen. When it is working again, look for any faint colored spots in the picture most prominent on light backgrounds. Mine is a yellow Y in the center of the screen.

If there are no spots, I would suggest you don't use the TV until you get it fixed because eventually it will damage your crt ($750). Of course, as I said, they have been unable to fix my problem and I have had no TV for three months.

Phillips 60'' projection hdtv wont turn on

Question do you see green led or light when pressing power button? If you can also listen for a high pitch noise coming from back of set. This would be an indication that the set has powersuppy problem or high voltage problems. If the set is dead and no noise then maybe fuse or open circuit.

My TV screen has no picture

If the light goes out you definitely have a short somewhere. If it blinks you have a fault, probably in the High Voltage circuit. Most common problem is a shorted Horizontal Output Transistor. Unless you are an experienced technician you probably need to have a reputable repair facility look at this one. Most will give you an estimate for free or for a small fee which will be deducted if you decide to have them fix it.
