View Full Version : Plasma TV: suddenly no picture

About three years ago my 32 inch Sony regular tube type TV began behaving poorly. The picture was quite dim and it took about 5 minutes to "warm up" before you'd get a picture. So we went out and bought a 42 inch Toshiba plasma TV as a replacement. I've loved it, until today. It was working perfectly this morning and now when we turn it on there is no picture. No picture whatsoever. There's sound, and the TV is getting power because the little power indicator turns green when you turn the TV on, but no fucking picture at all.

Oh, yeah. The regular tube type 32 inch Sony TV? It's in the basement. Still working just as it was when we bought this replacement (dim picture, long warmup time). But it beats no picture at all. This fuckin' thing is only 3 years old! What's the lifetime on these plasma TV's?

Any ideas out there? Perhaps there's some switch I could flip to turn the picture back on?

Try to see if signal from a DVD palyer works. If not call Toshiba Technical Support. We just bought a 60" Plasma which has just one pixel that is flickering green very very bright...annoying as hell...

Do you have a Warranty or Service contract from who you bought it from? If so call them for advice.

Check the strength of the power coming out of the wall. If it isn't strong enough things like that can happen.

We think we solved our problem. When the room air conditioner was turned off and the look temperature went up from 71 F to 75 F, the problem went away tonight.

We just bought a 60" Plasma which has just one pixel that is flickering green very very bright...annoying as hell...I tried that. No picture at all. I also called technical support, and they're not open on Sundays.

Do you have a Warranty or Service contract from who you bought it from? If so call them for advice.Sadly, no. I've always heard those were rip-offs.

Check the strength of the power coming out of the wall. If it isn't strong enough things like that can happen.I did buy one of those fancy power filter/strips that was recommended; but I don't have a power meter or anything. The laptop I'm using right now, though, is connected to the same electic socket, if that tells you anything.

Thanks for the replys. I can see by the label on the back that this TV was manufactured in April of 2006. The damned set is barely more than three years old and I paid like 2 grand for the fucking thing. I did a google search for Toshiba 42HP66 (my model) and this is the number one result:

i have a toshiba 42hp66 plasma tv. i turned it on and the screen is completely blank..no activity at all. the green power light is on but screen is dead. its about 3 years old and here's the answer:
,
regretfully, your TV has no doubt developed the same problem as that of many others of that model. It seems that Toshiba has a problem with having fast enough airflow through these TV's and results in components overheating especially if dust creates hot spots or blocks vents. Since the problem could be the YSUS and/or ZSUS and maybe driver boards, the repair is usually between $500 - $700 USD. The factory repair usually includes the technician ramping up the internal fan speed as well.
If I can be of any further assistance, please let me know. http://www.justanswer.com/questions/1xsh0-toshiba-42hp66-plasma-went-pop

It's a "good" deal because it's only 720p - and probably an crappy older model plasma. Why get a plasma? They're losing to LCD and are less reliable (as you've experienced)

One week.

We like Plasma because of the dynamic range 2 million to 1 and brightness (1500 cd/m2 vs. LCD at 500 cd/m2)

LCD is trying but not there yet.

I've not seen anything that indicates that LCD's are more reliable across the board, from what I can tell, the Toshiba model I bought was made with an underpowered cooling system that allowed the unit to overheat and break down. As to 720p v/s 1080p, I've got a 1080p LCD in the basement. I've always felt that the increased contrast of the 720p plasma yielded a much better picture. Vibrant colors and high contrast make for a better picture, in my book. Which is why I prefer plasma. Also, plasma is cheaper.

A neutral and informative review - Plasma Vs. LCD. (http://www.cnet.com.au/plasma-vs-lcd-which-is-right-for-you-240036500.htm)Yeah, I'd already watched that, but thanks for the link. It seems to favor plasma over LCD.

Mad, as i said to you before. The LCD's are MUCH better
You can't convince me on the picture. Well, I'm going out tommorow and I'll check some out side by side. The only thing that might push me to LCD is if I found out that they are, in fact, much more reliable.

No plasma. No LG.

Plasma has very short life span, and it's out of production. You'd get spots with faded colors all over the screen soon.

I had LG plasma and few other things manufactured by them. Plasma died in less than a year. LG is shitty brand.

Buy LCD. Picture quality isn't that great, but it's consistent quality.

The power consumption of plasmas is a lot higher than LCDs, so if your electricity bill and/or global warming worry you, you might want to consider LCD.

plasma are bad for the environment (compared with LCD). I actually went with a dirt cheap Chinese knock-off called SonIQ. 42" LCD 1080. It was about 1/4 the price of Samsung and depending on which one you buy it's either Samsung or LG that will make the panel - I wasn't going to pay an extra $2000 to have the Samsung stamp. The only draw back is there is no optical audio out. Which isn't a concern for me because I mainly use it for PS3 or PC both of which I run through the amp. Oh, the remote is cheap which does suck - probably that's 100% Chinese.

Toshiba hasn't been in the plasma game very long. Panasonic are the ones who have spent the R&D monies and the time to get it right.

Panasonic plasmas boast life expectancies now to be almost double LCD's. All the issues these tv's had earlier have been resolved by Panasonic, but most likely, not the other manufacturers.

Don't buy a plasma unless it's a Panasonic.

Can't you return/exchange it after you buy? I have just bought a new laptop 2 days ago. As all other electronic products, here in Germany I am allowed to return it / to exchange it within 2 weeks.

p.s.: this is my first post with my new laptop, yayy

This actually can be a problem, especially for those that use XBOX's. Microsoft originally had a number of complaints that their HDMI compatibility didn't work with certain screen models. So they generated a patch and that patch actually ended up frying my XBOX motherboard. What the patch actually did was rewrite the HDMI wrappers for the HDMI protocol because there were a couple of HDMI standards (Some screens were sold as HDMI Ready, others as just compatible)

It's possible with devices that can update drivers that these wrappers can be changed causing a screen to appear blank or even no sound. So it's best to test the screen using another input method (RGB/VGA etc)

As to the life expectancy of a screen, difficult to say what causing the main strain. The newer screens tend to have processor units to sharpen the HDMI input, and Plasma's usually have a high operating temperature. You'll probably find that if the screen is kept cooled and the vents aren't blocked by being placing the screen into a cavity like a cabinet that you'll have a longer life expectancy.

Yes, it is the room temperature. When cooled to 66 F, 3 pixels started flashing. Otherwise everything is fine. I was surprised to use the TV as a second monitor and yet the texts were crisp even a metre away. Now I planned to design a command center using that screen size.

Exactly, plus Sony has came down on their prices a lot. I can't understand how anyone can invest in any other brand. That's what I'm watching now, Sony Bravia XBR FTW!
