This all problem may exist in your tv
1. High voltage problem/ deflection circuit problem.
2. Shorted picture tubes.
3. Problem in the vertical deflection circuit.
4. Problem in the audio ouput circuit.
5. Problem in the convergence circuit.
6. Problem in the power supply regulation.
7. Problem in the portect circuit.
8. The common high voltage arcing that Toshiba sets do at the picture tube.
so for getting pictures gently tap on the side of tv if it works then there may be some loose connection you can fix it by soldering

This could be several diffferent circuits on the tv that is already busted that could cause this so I'm suggesting you to beirng this to anear repair center and have it repair there for your safety also , But if you have any experience in electronics you can try opening the TV and check for some busted IC inside it.

Hope that helps.......

The red light indicates that there is a power problem - a fuse has possibly blown.

there are several fuses in this tv. but they do not look like normal fuses. also when they blow it is for a reason. the most common reason is the convergence circuit. when this circuit goes bad it blows one or two of these fuses. you will need to get service for this television.

My toshiba TP48E60 model projection tv won' turn on, power light just blinks


Blinking of power LED are fault indications. Count the number of blinks occur at one time switch on. For this number, you can get an idea about the faulty section circuit inside it. It will make troubleshooting much narrower. If you wish to get more details about the blinking codes, check this link. Pull up older posts there.

TV won't turn on


Before going OFF, the standby LED might blink. These blinks are fault indication. The number of blink should be counted. Count the number of blinks at one time, before the TV goes OFF. [eg: 4 blinks Power SOS P Board; 6 blinks Driver SOS 1 SU / SD / SC Boards
(SC energy recovery circuit)] and so on. you can get more details from this site named 'Electro-help'. You can reach it by searching the keyword "electronicshelponline" by internet.

TV won't turn on. flashes a series of 5 red lights instead of turning green


Usually Sony and LG Blinking Codes are the same. Here is what I have.
  • Unit is dead, No blinks - Problem in the standby power section. Might check fuse,
  • Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.
  • One blink - not used for the self-diagnosis
  • Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.
  • Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit,
  • Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted.
  • Five 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. In addition, unit could be in IK blanking, try turning up screen slightly.
  • Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately.
  • Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.
  • Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code.
  • Nine blinks - Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing Make sure the regulator is -12 or -13 (negitive).
  • Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board.

Step 1: Turn off the PLAYSTATION 3 by holding the Power button on the front of the unit till the Power light is red.

Step 2:
  1. Touch and hold the Power button, you will hear the first beep, meaning the PLAYSTATION 3 is powering on.
  2. Continue to hold the Power button and after about 5 seconds, you will hear a second beep, indicating the video reset.
  3. Continue to hold the Power button and after about another 5 seconds you will hear a third beep and the system will power off (Power light is red).

Step 3:
  1. Touch and hold the Power button AGAIN, you will hear the first beep, again for the PLAYSTATION 3 to power on.
  2. Continue to hold the Power button and after about 5 seconds, you will hear a second beep for video reset.
  3. Continue to hold the Power button and after about another 5 seconds you will hear a quick double beep. At that point release the Power button. If you succeeded in activating Safe Mode, you will see a message on the screen saying, "Connect the controller using a USB cable and then press the PS button."
  4. Connect a USB cable to the controller and the PLAYSTATION 3 and press the PS button to enter Safe Mode.
  5. Then you will see the Safe Mode menu.

Status light blinking red


If it is a lamp error try this:
When the lamp exceeds 2100 hoursof service, the projector cannot turn on and the manu is not displayed. Do the following:
For VT670/VT470 Press the help button on the remote control for a minimum of ten seconds.

For VT570/VT47 Press and hold the power and the exit buttons on the remote control simultaneously for a minimum of ten seconds. When the lamp time clock is reset to zero, the lamp indicator goes out. Hope this helps! :]
