Question about Philips Magnavox 27MS343S 27" TV

2 Answers

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 won't turn on?

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!

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.

Picture & sound go on & off every sec, red light blinks 5 times


helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.
