SOURCE: have mitsu model # ws-65813 wont turn on

You have a common problem in the DM (Digital Module), more specifically the DM power supply. There are four electrolytic caps in that supply 16v/1000uf that are bad and likely buldged from heat stress. Replacing these caps and the E2P module, a small stand-up board further back on the main DM board should restore normal operation...
You might be lucky enough to have a tech come out and simply replace those caps in-home. It's not a really big job for a qualified tech.
Hope this helps!

You would need to check the power supply and shutdown circuit for a faulty component. There is a manual called Toshiba power spply and shutdown circuitry available for 10.99 at the following link, That manual covers your model as well as quite a few other toshiba models. It gives step by step instructions on what to check, And the site offers ree unlimited support to help you with your diagnosing. They will een email the manual to you instantly if you returnto the site and click thecontact us link requesting that they email it instead of mail it.

SOURCE: Magnavox 32mf231d - Just a blinking green light, No Power

I had this problem, but saw other places that it was a cheesy capacitor on the power supply circuit board causing this. I opened it up and took the power supply board out and it was obvious which capacitor was bad...top was bulging and had black stuff on it. It was rated 2200 uF @ 25V...got a new one @ Radio Shack that was 2200 uF @ 35v. Soldered it in (I stink @ soldering, but gave it a shot and it was EZ). Watching the first weekend of college football w/o waiting on a flashing green light for up to an hour so the TV would start! I'm going to try to find the other websites that directed me to this to say THANK YOU...BTW my brother used to have fits with several Magnovox TV's and thier power supplies back in the old tube style TV days. I thought I didn't need to worry about this with an HD flatscreen, but was wrong. I will think twice before buying a Phillips/Magnavox/Funai/whatever else they are again. They have a long list of complaints and I believe a class action lawsuit to refer to about this problem. They should have stepped up and done something!

I have a sharp LC-60LE831U tv that is flashing a code on the power light 2 slow 5 fast. No picture or sound and factory resets I have tried do not seem to work, any ideas or suggestions.

Some model Sharp sets, they have used the Philips main board. Yours should be one like that. These blinking codes denotes it. That means; your TV is a not duplicate one. Sharp did it for some sets of their own. So, when you try to count the blinking codes of such set, you should follow the way of how to count the blinking codes to Philips TVs.
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/
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.
Counting of number of blinks to Philips TVs is entirely different to that of other brand TVs. It is not a direct count procedure. The site have details about how to count the number of LED blinks [Fault Codes] to Philips brand TVs are given; along with details of the faulty circuit location.

My Sharp tv was affected by a power surge and I have no power. Is there a way to determine if it is the power supply? Thanks

Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

A power surge zapped my TV, I turned it back on, it tried to bring up the picture but shut off again. A green light keeps blinking.

if a power surge shut down the unit than a circuit, capacitor or fuse is blown and or burnt and you wont smell that most of the time and since it does have power fuse wasnt blown so a circuit -diode-capacitor is fried somewhere problem is common for an electricial damaged tv but to diagnose an electronic tech would need to tear it apart

Sharp tv 70 inch wont turn on blinking 5 times fast 2 times slow

Which model do you have because the blink code differs from model to model. Did you try a hard reset? Meaning, unplug the unit, wait a minute or two, then holding the power switch down, plug the unit back in while still holding the power switch down. When it comes back on, release the button.

Brand new TV, spotty HDMI functionality (sometimes recognizes cable box or comupter, but not always). Attempted firmware update on a Sharp Aquos LC-32SH7E (European model). Don't think it ever...

Did you go through the entire factory reset? When you plugged in the power cord did you continue to hold the volume - and input button until the television powered on and a K appeared on the screen never releasing at all?

Force the tv on by holding down channel down and volume + on the tv while plugging the tv in. See if the tv still lights up and if you get audio.

Attempted flash update on a Sharp Aquos LC-65SE94U. TV rebooted and now get a black screen (power light blinks 3 times and ops once with the 3rd power light blink) Called Sharp and they said to factory...

Unplug the power and leave it unplugged for a few minutes.
Then press and hold the buttons on the TV while another person plugs it in. Hold the buttons down for 30 seconds, or until the set beeps.

It is possible that the flash update was not successful for some reason, in which case the set may have to be returned to the factory, or a factory service center to be reflashed properly.
