You likely have bad convergence output IC's that have caused one of the supply fuses to blow. This repair will have to be performed by a qualified technician. If you were in our area and has us repair this the total cost of the repair would be about $340 if I am correct about the cause of your problem.

SOURCE: PT-45LC12 Problem after startup

When the lamp flashes 4 times this is what the error code means IC 2301 pin 11 has detected an LCD error which is caused by an error in the LCD power CBA. which means the lamp voltage has become more than 130 volts or less than 30 volts. Or the lamp current is more than 5 amps, or the lamp is cracked. Its one of thos 3 reasons that will make the lamp indicator blink 4 times. Hope this helps. If you need the service manual for this model you can get one emailed to you from the following link.

this is a crt type tv- no lamps just crt's if it was moved recently then a seal could have been damaged on the crt cuasing coolant to leak down the neck getting into the socket. this will cause trouble for sure also could have a crack in the crt. look for a sticky liquid in the bottom of the unit.
sometime the crt's can ark and rip out a video output chip on the crt socket check it out.
not common but not unheard of.cheers

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

I would check the fuse on the main board. Check the Capacitors on the Power Supply board. Seeing that you unplugged it and replugged it in you might have bad caps that were weak to begin with. Please learn how to safely work on a TV before attempting . Even when a tv is unplugged it has enough power to kill you. Discharge all Capacitors first. make sure its unplugged of course.

Model 55X70 Toshiba Projection tv


dont know about warranties but horizontal lines means your horizontal frequency which runs about everything has drifted off sync and if too high or low it will activate shut down circuits in high voltage and power suppy, even causing HOT transistor to short. good luck and call a tech.

Toshiba Theaterview HD 52"


I have the same tv and had it fixed the problem is most likely the power supply a $50.00 part but I suggest you have a repairman do the fix. Total cost should be around $250.00 for labor and parts.Also unplug your tv for over 4 hours then plug it back in to see if it works they call this a hard reset.If this does not work after 4 hours try unplugging it overnight and then try it. That is what I did to use the tv until I got it fixed. The only thing it could be is the convergence circuitv if this is the case it should cost about $400.00
