Hi,
This symptom appears when power supply board got problem in tv. It seems power supply board is defective in tv that is why it is not turning On or it wont show power in indicator.
If you are handy with electronics stuff and have prior experience then unplug tv from wall socket, take off back of tv by removing screws at top-bottom and sides and check main fuse located on power supply board, replace it if found blown, replug tv and check.
If fuse blow again then replace power supply board as power part number written on it.
Hope these info will help you.
Let me know if you have additional question.
Thanks.

When I turn on my 50" Plasma TV the light goes from red to green. The Green LED flashes 14 times then solid. There is a white raster but no picture or sound.


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

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.

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 Pioneer Elite PRO-111FD just shut off on it's own, and now won't turn back on. No green or red indicator light... nothing. Any suggestions?


Check your power source (electrical outlet) and the power cable. If electrical outlet is ok, try using a different power cable (the cable that you plug on to the electrical outlet going to your TV set). If everything is ok but still no indicator light, call your technician there might be a problem with the TV power supply.

Would be great to know the Make and the Model # and if its still under warranty as I strongly believe you are having an issue with the main power supply.

LG 26LG30 screen suddently went blank. Light flashing blue/red


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

What red light are you referring to? If you are talking about the red l-e-d power light beneath the screen, that is the power off light. If that red light light momentarily turns green and then immediately red again when you are attempting to turn the tv on, that indicates a bad power supply.

Sony KDF-46E2000 - Screen Goes Blank


You definitely have a bad lamp. Sony rates the lamp life at between 4000 and 8000 hours. There are 3 things that effect the lamp life, listed in order of importance:
1) number of times the lamp is turned on and off. Every time the lamp is first fired, it takes life off the lamp. Customers I see that turn the TV on in the morning, leave it on all day and then turn it off on the evening can get up to 12000 lamp hours
2) ventilation. Be sure you have at least 6 inches of open space all the way around the set and that the vents are clear of dust and debris.
3) power. If the power is interrupted when the set is on, there cannot be a proper cool down cycle. The fans will run after you turn the set off to properly cool it down, if the power is lost this cannot happen. If your power is unreliable, buy a small UPS to let the set finish a cool down cycle

Occasionally a lamp will faill before the average lamp time due to being defective. from your purchase date it sounds like you got about average lamp time. Be sure to purchase AN ORIGINAL SONY LAMP as a replacement, becuase the aftermarket lamps are bad news, Be sure to rate this solution. Thanks!
