Re: nice burn in on sanyo lcd at walmart
Walmart is disgusting. Ethical issues aside (China, anti-competitive etc.), they sell a lot of really cheaply made shit and the one near my house always looks as if everything could use a really good cleaning (except the merchandise itself). -
Re: nice burn in on sanyo lcd at walmart
Sanyo is low quality and when needs service be prepared to pay wide open even TV is cheap to begin with. Good LCDs don't burn.

Re: nice burn in on sanyo lcd at walmart
Recent Consumer Reports surveys show that Sanyo LCDs have one of the lowest failure rates. Actually I don't think they reveal any statistically significant difference in failures except for Mitsubishi and the worst brands, like Westinghouse and Polaroid.Originally posted by WizardComment

Re: nice burn in on sanyo lcd at walmart
I gotta wonder if that is a plasma and not an LCD. Maybe some employee saw a sticker on the floor and put it on the wrong tv? I have never seen LCDs with burn in. In school they told us that it was impossible, but not everything I learned was totally true.Originally posted by Wizard
Really? Sanyo is junk? I personally like the Sanyo product and company. Even the crts in the 90's I thought were good value (cheap) products.I agree sir. I believe the problem with your television is that you need the picture tube replaced.Comment

Re: nice burn in on sanyo lcd at walmart
i have seen image persistance on lcd sets.mostly on cheap panels like the chi mei in an audiovox 26" on my bench.
it goes away quickly and is most easily spotted on a still image with a brightly colored area.a negative of that colored area will be seen in some scenes later.
example is a webpage with bluegreen stripes down the sides.on a white screen you will see pink stripes.Comment

Re: nice burn in on sanyo lcd at walmart
I've never seen a LCD burn-in like that.....even at our local walfart, which never shuts theirs off. I've seen burns on some of their plasmas though, all Sanyo's ironically enough. I think our local walmart rotates the stock often enough to prevent most of this. they periodically sell floor models dirt cheap.<--- Badcaps.net Founder

Re: nice burn in on sanyo lcd at walmart
I do know that LCDs do not burn in, but plasmas do.
Apparently, they are not aware of the need to prevent this happening!My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.Comment

Re: nice burn in on sanyo lcd at walmart
"Burn in", while descriptive of the appearance is probably not a good term, but a permanent image on an LCD panel is possible.Originally posted by japlytic
An LCD panel works by using a polarizing voltage across the cells in the panel. Under some circumstances (usually an electronic failure) they will electrolyze the liquid in the cells. It won't happen in a panel that is working properly, but the chearper they build them the more likely it is.

Re: nice burn in on sanyo lcd at walmart
My Sanyo 26" LCD TV also gets image burn in.
At first it would go away after awhile but this last burn in that happened from falling asleep while it was on a show that was 4:3 ratio and the sides are a permanent burn in now.
I always thought LCD's were pretty safe from burn in owning this sanyo has proven different also have seen the old Dell LCD TV's get burn in.
Purchased the Philips 5000 series LCD 4 months ago and noticed right away it does not get burn in like my Sanyo does.Last edited by safesinger; 05-12-2010, 09:23 PM.Comment

Re: nice burn in on sanyo lcd at walmart
I had read on another video forum that people were getting burn-in images on HD sets that were getting 'pillarbox' mode images. Either side of the display would have a different brightness and/or color level displayed by the pixels that had not gotten as much usage when a full-screen HD image was displayed.

Re: nice burn in on sanyo lcd at walmart
These panels are meant to be driven with a high frequency AC signal, so there is no overall DC bias across each cell. If there is a failure like you mention, DC might be applied to the cells. This happens with LCDs from calculators etc. Try connecting a battery to the segments. They will work but they will be damaged if left for a while.
I guess the most common fault would be T-con going bad, it's possible it could fail in a way that the picture continues to work but a DC bias is applied. Like some amplifiers can kill speakers by keeping a DC bias across the output terminals - yet you probably wouldn't notice the difference in audio.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: nice burn in on sanyo lcd at walmart
As long as the burn-in isn't really severe, you can usually get rid of it by displaying a solid white picture for a relatively long time (couple hours or more)

Well I have a friend of mine that has a 27" TV that he uses as a CCTV monitor, its going on 5 years old. the gridlines are burned into the LCD display.

Greetings everyone,
I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...
The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.
Upon closer inspection... -
Hey all
I've been working on a 1984 Sanyo 27" color TV which had a smattering of bad caps in the video switching circuit. I found this oddball little 1uF 25V cap which looks to me like an early polymer, but I can't find concrete info proving it. I know Sanyo was a big player in early polymer cap development and this is the time period where they were just getting on the market, so I'm wondering if anyone has crusty old datasheets that could help identify it and determine if my suspicions are right? It has the same epoxy end seal and font/formatting as some old stock Os-Cons I've got laying...

Hello all!
Westinghouse TV WD48FAB100 Not Powering On – Burn Mark Found on Power Supply .
I have a Westinghouse LED TV, model WD48FAB100 that is not powering on. Upon removing the back cover, I noticed a burn mark where the AC cord connects to the power supply/main board. In this model, there is only one board combining the two functions. Previous owner said the TV experienced a lightening strike, but who knows. I checked the main fuse, tested OK. Here are a collection of readings from the power supply ports. Looking for some guidance on what to test/check next.... -
I have a Sony 75x940e that I just fixed with the help of the forum (bad emmc). For the last couple of months I was noticing some burn in of the android home icons on dark backgrounds (photo is attached). I always thought VA panels were immune to burn ins. Is there anything I can do to fix it? Could it be because of a failing component other than the panel itself?...07-19-2023, 09:23 PM -
Hey All,
I have a Sanyo DP5834 that did have an issue with the backlights, but I disassembled the unit and repaired the LED strips by resoldering all of the connectors. Now I've reassembled it and I have backlights and sound, but a grayish screen. I can tap on the screen and see that it's on, but no picture. All voltages seem to be correct on the power board.
Based on the LCD Flat panel TV troubleshooting guide by Bud Martin, I'm thinking the T-Con has failed because I'm getting 12v both into and out of FP1 on the T-Con. Am I on the right track?
Thanks,...
