Question about Mitsubishi WD-52525 52" Rear Projection HDTV

Open Question

My TV has hundreds of little white speckles showing up on the screen, kind of like white noise. They aren't staying in one place just flashing all over the screen. A green bar flashes as well every so often. I took the problem to a local TV specialist retailer and they said that it could be a power surge, and that I might need to purchase a Surge protector that filters out the problem. Any idea on what this could be?

The surge protection built into the typical power strip is primitive and the component(s) that provide protection by conducting (shorting) between the hot and neutral degrade with repeated activation. They are worth much when new and after having switched a few times, the voltage breakdown point moves uprange and they become less effective.
Most more expensive electronic systems have better internal protection than that afforded by the majority of the power strips and there might be an internal fuse that blew that can be replaced. I'm afraid however that the main power supply has taken the hit.
The supply is normally built on a separate boardsince these are often out-sourced by set manufacturers.

Unplug your set overnight to allow potentiallyhazardous voltages to discharge, remove the lower back panel of the set so you cansee the guts.
Look for a smaller board with larger parts onit; some cylindrical (capacitors), others block-like and relatively large(chokes and transformers).
You should also see a relationship between theboard and the incoming AC.
Check the board for a label or if not present, astamped-on number.
Call the manufacturer's service center with yourTV model number and the number found on that board and inquire aboutrepair/replacement costs; if both are offered, they won't be that muchdifferent.
If you must buy a new board, don't dispose ofthe failed one as there are smaller companies that can repair it for less thanthe mfr. and then keep it as a spare as this problem will likely arise again.

If you reside in an area of frequent electrical storms, I highly recommend you install or have installed a 'whole house' surge protector. These are either installed in an existing main breaker box or in an auxillary box next to the breaker.
The device and installation labor fall between $150 - $300 US and have an included insurance policy that covers losses of 10 or 25 thousand dollars.

SOURCE: After power outage timer light is flashing and tv

We had a similar problem with our Toshiba. It turned out to be that the mercury bulb was toast. Open the owner's manual & look in the Troubleshooting section. The blinking for us was indicitive of a bad bulb. Sure enough, we took it out & it was obviously cooked. Don't buy from a local store, buy it online. You'll save between $30-100 & our "cheaper" bulb has been working for 2 years. Hope this helps!

White wavey lines with dots or speckles.

The "white line" at the top of the screen is usually associated with "VBI Information" - the stuff that carries closed captioning, etc. This is usually only visible on upconverted SD material on HD channels and is usually the fault of the affiliate not doing the upconversion properly.

Colorful "speckles" on screen

Could be the screen burn from watching T.V. on a show and the thing burnt in (in this case the colors, yes it can burn colors.) and there's nothing you can do. The insides of the T.V.'s have plasma gases which can flow out of control.

I get white speckles on black parts of my picture

In years past the problem was created from something that has a bad motor in the area of your house or on the power lines. The 'speckles' sound like ignition noise. I have traced them to strange things as a butter control in a refrigerator. To be sure if that this is causing your problem you can take a radio and tune it around 550 mhz and you will hear a crackle or buzz. Best to use a battery operated radio and wave and walk around until you get the loudest noise and that will be the source of your 'speckles'. Could be as simple as a loose connection in your panel box.

TV buzzing when showing whites and bright colours

I had the same problem when I connected my new At&T cable to the tv card in my PC. I did a little internet research and found out that the problem is called "video buzz". It is where the video signal bleeds into the audio signal. I was connect via coax to the cable box. I was able to fix it on my system by "fine tuning" channel three (my TV card has this capablility). Your system may or may not have this feature. If you are connecting using the A/V input it may be something else.
