Why won't it start?


The computer is not producing a video signal.
The varistors in the surge protector are probably burned out, or there is some other problem in the surge protector.
The monitor is very likely OK.

TV quits working, screen goes black and red light next to power green light flashes 4 quick flashes . After a second or two of no flashing,red light repeats "code" flash. We pull the power plug at the TV,...


The Sony diagnostic routine for 4 blinks indicates it to be a vertical deflection problem.

Did you see a solid horizontal line in the center of the screen prior to it going out? If so, that is a tell tale sign for vertical problems.

basic sony reset below

The STANDBY light will flash if the television detects an issue within the television. Some of these issues can be resolved simply by following the steps below to reset the television.

  1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
  5. Turn on the television.

If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center

MY SONY HBD-DZ810 HOME THEATER IS CONSTANTLY SHOWING PUSH POWER PROTECTOR


The "PROTECT" and "PUSH POWER" messages will flash alternately when the protective device of the amplifier has been activated because a strong signal was input, or if there is a short-circuit detected. Press the POWER button on the unit to turn off the system, and check the following items after "STANDBY" disappears.

1) Are the + and - speaker cords short-circuited?
2) Are you using only the specified speakers?.
3) Is anything blocking the ventilation holes of the system?

You may also refer to the following link for additional troubleshooting steps.

When home theater is turn on, protector push power is flashed on thee screen. player will not function further. volume level is 9. currently can't be turn down.


Protector means there is a short circuit somewhere in either the speakers, the wiring or inside the unit itself....you can try disconnecting all the speakers and then turning on the unit...if the protector goes away, then you have a bad speaker or bad wiring to the speakers....if the problem stays, then there is a faulty circuit in the receiver itself and will need to be serviced

It flashes the word - protector


Hiya,
Disconnect all speakers at the receiver and power it back on. If it stays on, check all speaker wires and speakers for shorts (touching wires). If it cuts out, it needs to be serviced.

KP57WV600 SCREEN TURNS GREEN THEN BLANK


The self-diagnostic function of the projection TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue. As per the two examples below, some of the issues may be resolved without the need for service.
  • If the STANDBY light flashes three times in sequence, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
  • If the STANDBY light flashes four times in sequence, the TV may be overheating. To resolve this issue, ensure that the back of the TV is well ventilated.
If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
  1. Turn off the television. IMPORTANT: For a projection TV that uses an internal lamp, wait 5 minutes after turning off the TV to allow the lamp to cool before continuing with the following steps.
  2. Unplug the TV power cord from the electrical outlet.
  3. Let the TV remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the TV is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the TV.
  5. Turn on the television. NOTE: If the TV does not turn on immediately, the fan may need to finish its cycle. This is part of the cooling process for some projection TVs and is normal operation. After the fan turns off, attempt to turn the TV on again.
If the issue is still unresolved after following all of the troubleshooting steps, service may be required . Please note the number of times the STANDBY light flashes and relay that information to the service center.

Dell monitor problem


Disconnect and reconnect both ends of the video cable (while the computer and monitor are both off). Also disconnect and reconnect the power cable. Is the power cable plugged into the same surge protector as the computer? And also try a different outlet on the surge protector for the monitor.
