Heard a pop, tv went off, then doesnt come back on

Your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. The sound is it starting up, shutting down, over and over.

You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

Have a Toshiba TP50G50 Projection televison with no picture. Have 100 volts to power board

100 volts is too low to power the entire projection TV. Usually with rear projection TVs there are three tubes that create your picture on the screen. To power those tubes, they each require a high voltage (usually around 10,000 volts - yes ten thousand) that is produced by a high-voltage step-up transformer call a 'Tripler' - since it powers all three tubes. This device and the rest of the TV require full utility voltage (120 - 130 volts AC) to properly power the unit. Correct the voltage and try again - is the house / residence voltage like that in each room? IF so, you probably have other issues with devices you probably haven't picked up on.

Toshiba TP50G50 Theaterview picture is double with red color only

Your alignment is off. Go to the set up menu then convergence. hit right and you will be in the convergence menu. select the color that is not in alignment. The green line does not move. if blue and green are lined up the line will be cyan. if red and green are lined up the line will be yellow. when all three are lined up the color will be light. Best of luck!

Not turn on i do not have 24v. Was watching TV for three hours when I was finished the set would not turn off from either remote or front panel. Unplugged unit and left overnight. When I plugged the unit...

Good Day,
The most common problem with this Model is the Caps on the Main Board, but to make sure pull the codes. Follow this procedure:
This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. MAY BE INTERMITTENT, SELF-DIAGNOSIS ERROR 23 OR 24. CHECK SOLDER CONNECTIONS AT CONNECTOR "DY" ON THE YOKES. 2. SHUTDOWN AT POWER WITH SELF-DIAGNOSIS ERROR 23 OR 24. CHECK C411 2200 UFD 35 V AND C412 10 UFD 50 V, BOTH LOCATED ON THE MAIN PCB. Good Luck, big IRISH.

Mitsubishi wt-42413 Power problem

Okay try to distinguish if the three blinks is 1 pause then 2 blinks or 2blinks pause 1 blink. As the set will only blink a two digit code 12 meaning no error detected and 21 meaning the set is hutdown due to xray protection.

My RCA D52W20 will not stay on

Clicking sound is power relay engaging. If all systems are not functioning properly, unit will shut down to prevent further damage and/or fire hazard

No picture tp50g50

Sounds as thought you have a dead B+ from the power supply board. Replacement of the board should be a certain fix. The power supply could be fixed with the help of a good service technician. I hope this has helped.
