This really depends on the make and model of the TV you are referring to. More than likely one or both of two things are happening. 1) There is a fan out causing the TV to get too hot and a safety switch is shutting it down to protect the TV from further damage. Or. 20 there is a bad safety switch telling the TV has an issue when it really does not. Another thing that could be going on .... It seems modern TVs have a tendency to burn out capacitors and bad capacitors will cause this behavior as well.

Your best bet is to use Google to search for common problems with your specific brand and model of TV. Also look for flashing lights on the front of the TV that may be blinking in patterns, these patterns may tell you what the problem is. ie; 3 blinks bad fan or 4 blinks bulb not seated properly etc.

I have a hitachi 55vs69 projection television. Lately, it has been shutting down every 15 minutes or so. The screen turns dark but you can still hear video until about a couple minutes later the led light...


Hi,

First step is to unplug the 120 vac power for a few minutes to clear any corrupted data that may be present in the controller circuits.

If a "power" reset doesn't help and the lamp or bulb is installed correctly, you most likely have a failed replacement bulb. The symptoms are all standard indications of a failed bulb.

Reduced lamp life can be caused by:
  1. Lightning and other 120 vac power bumps.
  2. Collisions with vacuum cleaners or other incidental impacts while the TV bulb is operating.
  3. Starting the TV without a complete cool down. Bulb will consume a small amount of mercury with each start. Excessive consumption occurs when bulb is "Hot" and turned on.
  4. Wrong bulb installed as replacement.(Philips original replaced with Osram or El Cheapo)
  5. Poor quality or damaged bulb installed as replacement.
  6. Bulb damaged during replacement
  7. Bulb installed incorrectly at replacement.
Almost all Hitachi 55vs69 "No Picture" failures are related to the bulb.

Many of our service events are with customers that purchased El Cheapo bulbs from "shopping cart" websites or picked up a bulb from a small "local" TV shop. Many small shops stock of 3 or 4 bulbs and try to substitute or cross reference to fit more than 200 models of TVs from 7 different manufacturers. If a premature bulb failure occurs, they have the opportunity to sell you some expensive service.

Go here to see all of the different Hitachi TV bulbs that are available in Canada.

Use the correct bulb for your model and if you are uncomfortable with the replacement procedure, get local service.

New bulb/TV still shuts down


Its far more likely the result of the power pwb capacitors that have failed. As the 34 code will appear if the capacitors fail on the Power PWB. You can get the V26 DLP Power repair kit at the following link.with free instructions

Tv cuts off and green light flashes


Yup, it seems a lamp problem can give a blinking green light over the 10 times (1 - 10 times for diagnostic codes), but in my case rather than replace the bulb if it works for a minute then resets with the green light blinking, do what I did.
Take the lamp out and inspect it, it has breather screens top and bottom, if it cant breath because there clogged with dust, clean them, and you can remove the screens, use q-tips and clean the inside. I saved the cost of a lamp and it's working fine!

Sony LCD television will not power on.


I get 5 blinking red lights for about a minute or so before it powers back down. The Sony TV has a specific light that i presume is supposed to light up when the bulb is out. I'm unsure if this is what it is.
no picture, no sound. tries to boot with green light blinking a few times. then goes to red blinking light, six in all, then waits a few moments, then another 6 blinking red light.
Bulb was already replaced several months ago but we do have the TV on for long periods of time.
