Panasonic Plasma TV m# pdp503pu

I pushed on button on remote yesterday and heard a pop, like a fuse blowing, TV didn't come on and in lower left corner green lite that usually is on whn tv is on was flashing red. I unplugged TV, vaccummed all vents and tried again 1 hour later, still no screen. Is this a costly fix or should I go get one ?

VR,
Bill

It seems that tv's fues is blown. May be due to internal shortcircuit ( dust accumulation on the pcb and humidity)or some capacitor is short. I think it will not be a costly job. Go and get it done by a good service person. Better you contact Panasonic authorised service station.

SOURCE: Blue screen and red padlock

It sounds to me like a child lock function, which is usually what the screen + padlock is on TVs. Usually your original remote would have a button / sequence to unlock the mode. If you still have your original remote, look for a child lock button or refer to your remote manual (and/or TV manual for the child lock feature) to unlock the mode.

SOURCE: tv won't turn on

Your problem could be the Convergence board is loading down the power supplies and will not let the TV set come on, or the power/deflection board, part number AA94-08574A, or the STR type regulator IC, part number AA13-00105A. If you locate the convergence board, unplug the connectors, and see if the set will come on. if the set does come on, replace both of the STK convergence IC's at once. The part numbers for those IC's are STK392-40. You can get the original replacement IC's from MCM electronics for about 15 to 16 bucks a piece. Do not use the less expensive STK IC's as they are not the same. the replacement IC's should have the name of SANYO printed right on the face of the IC's. Good Luck

bad components on the power board needs to have service tech look into blown capacitors or transformer on the power board inside the tv.

SOURCE: Panasonic 32 inch LCD TV will not turn on-red light flashing

The number of flashes is an error code. Count the number of flash. It looks like one of the boards in your set is failing intermittently. Panasonic codes for a guide as a starting point. Exact board STILL has to be verified;
One Blink: One blink of the power LED indicates a problem in the inverter circuit located on the LCD panel. The inverter board is not to be repaired in the field. Therefore a replacement is required.
Three Blinks: Three blinks of the power LED indicates an over-current or over-voltage condition in one of the DC supplies of the AP board. The AP board is repairable. Therefore the use of an ohmmeter and peak-hold-voltmeter is required to determine the cause of the shutdown. An over-voltage condition is definitely a defect of the AP board. An over-current condition may be due to a short circuit located in the AP board, A board, or the LCD panel.
Five, Seven, or Eight Blinks: The A board is responsible for five, seven or eight blinks of the power LED. The MAIN +3.3V, MAIN +5V, and MAIN +9V sources are all produced on the A board. The detection input pins of the MPU, IC1100, monitor for their presence.
Four or Six Blinks: The AP board is responsible for four or six blinks of the power LED. The DTV9V, and SUB_5V sources are produced on the AP board. The MPU IC1100 monitors for their presence when the unit is connected to AC Power. A short or open circuit on the A board may also be responsible for their absence.
Nine Blinks: Nine blinks of the power LED is due a short circuit in the audio output circuit (s) of the unit. The audio output circuit is located on the A board. Confirm the status of the speakers. If defective, perform a replacement. If ok, replace the A board.
Ten Blinks: Ten blinks of the power LED indicates a malfunction of IC4200, the frame converter. This IC resides on the A board. Therefore ten blinks of the power LED requires the replacement of the A board.

My Panasonic TH-50PZ7OOU will not turn on. The red light on the lower left is on, but the screen is completely dark. pressing power button on both TV and Remote control gets no response.


Try to power it up with the remote control. When you hear the relay's click, see how many times the red light flashes. This will tell us what the fault is.

Should be a button on the bottom left of the remote labeled R-TUNE. That will send you to the last previously viewed channel.

50"lg plasma tv


The popping noise you heard it's probably a capacitor blowing up in the power supply circuitry. If the TV is less than one year old, still covered under manufacturers warranty.
