Question about Hitachi 42EDT41 42 in. HD-Ready Plasma Television

1 Answer

Hitachi 42EDT41 Had a major surge hit my house. Now my component input does not work, and my TV shuts off randomly. I also noticed white and blue pixels going on and off all over the TV while watching movies and playing games. Does anyone else have this problem as far as the pixels are concerned? Is this a serious issue? Should I start looking for a new set?

There may be a software glitch. Call Hitachi customer service and ask if your model needs a firmware update to get rid of the sparkles.They also have a website

I have a hitachi tv model 42edt41 year 2004,2005

I have the same tv and had the same problem. I found a posting that stated to re-solder a connection on the cable for the "y" boards. I used this and my tv is perfect now. The part that needs to be re-soldered is the ribbon cables at the bottom of the tv that go from the boards straight to the screen. On the inside of this ribbon cables there are 4 small components that have "100" on them. On each end of each of these pieces, re-solder them. Since I had my tv completely apart I re-soldered all of them across the bottom. No problems now!

Y Component Cable Related - Internal Static Noise

It sounds like one of those cables has a defective ground. The static noise you are experiencing is cause by the cables not inside the TV. Try using different cables to isolate the problem and get new ones.
Good Luck.

No Picture on a Hitachi 42EDT41A

Then it is probably not cold solder joints. You wouldn't think that an lcd TV would need a high voltage transformer but it does. They are very small compared to CRT televisions but they power up the screen. Without it you have no backround light to veiw what is there. There are two neon lamps on either side of the screen but they rarley go bad. My guess is the transformer ot the power supply feeding it.

My componet/av only shows black and white on my vizio vp422

The 37" Vizio I just bought has a very confusing feature where the same input can be used as either the Y channel of the component or the full video channel for composite. If you plug a component source into the TV and then select the composite input ("AV" on the remote), you will see a black and white version of the full component signal (makes sense as the Y channel is just the luminance component). As sad as it is, I was stumped by this for a while until I happened to hit "COMP" and got full color. FWIW, the manual warns about this, but it really doesn't emphasize the point. I wonder how many returns they get because of this.

Do the lines move at all, or are they static? Someone else had a similar problem, and a fix that might work for you was posted at:

Hitachi 42"

Its impossible to say without knowing more than that. If the TV does not detect any signal on whichever input (other than CATV) your on, it will power down. Make sure you are getting an input signal and make sure you are on the right input on the screen.

More info on your problem and i could probably help you better!

Lose audio to receiver when connecting component video input

Have the exact same problem, opened a case file with Hitachi.

I have a feeling it's a firmware problem -- hopefully they will make my life easy and mail me the proper cable I can connect from PC to TV, and the software to run such an upgrade (as opposed to packing this big thing up and carting it off to a service center).

I'll post my experiences.

Red patches

What kind of input signal are you watching? Does the issue happen no matter the input you're using (RF, HDMI, Composite, Component)?
