My TV (Toshiba or Samsung or something like that) a flat screen will uncontrollably go down in volume and if I take the batteries out of the remote it still adjusts it's own volume down. I've tried th


Well the difference between a Samsung and Toshiba are pretty extensive, so without knowing what TV and what model, we cant help very thoroughly. Have you checked with the manufacturer directly? it sounds like the TV is quite new.

I have a 2010 50" Samsung plasma hd 3d tv. I woke up one morning and had no picture. I had sound and could change the channels and listen to whatever was on, just no picture. no picture in menu, or source...


It is not an easy task to repair a Plasma TV, for any inexperienced user. It will be best to contact any service technician. If you're sound in electronics, and wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window.

I have a samsung plasma 42" model hps4253x/xaa -the plasma has a green vertical line at the left side.


Did it come this way? If so I would recommend returning the TV. I'm guessing you have tried using different channels, inputs, etc. If not please do so to determine if it might be specific to an input or channel. This is not something that someone will be able to talk you through via message boards. I would first try calling the manufacturer and then the retailer if you continue to have problems.

Sound no picture


Sound but no picture....
Should ask yourself, does it PRIME? Meaning, That's where the Plasma panel lights up a little for about 10 seconds after startup. -- If it doesn't prime, then you need either the SMPS, YZUS, possibly both. OR you might need to check the ZSUZ. Driver boards can be culprits too.
And can you even get to the Menu, Volume, etc. but just picture?
Then you need the signal board.
Unfortunately that's pretty common with Plasmas. Can burn out or burn "in" easily.

Here's a great forum you might like. http://www.austech.info/electronics/20607-lg-plasma-tv-has-no-picture.html

Different Brand but similar problem. This site is excellent for do it yourselfers. As for Samsung Parts, be thankful if you are a DIY-er that the parts are much cheaper if you install yourself. Separate with installation adds up very quickly. Personally, I decided to go with the Rear Projection Samsung several years ago and haven't had any major problems. Heard then that Samsung was having lots of complications of this nature.

Here's the link to Samsung Site:

http://www.samsung.com/us/support/owners/product/SPN4235

You can try the tricks on this site:

http://www.broadbandreports.com/forum/r22996341-samsung-spn4235-sound-but-no-picture

To be honest though sounds like either bad SMPS and/or bad Y-SUS pcb's.

Wish you good luck.

Model hps4253x/xaa vertical lines throughout screen


Need more specfic info. Are the lines on all sources? Are the lines as thin as a Pinstripe?. The possible causes are: The Main bd is bad or the P-Logic bd is bad or the Plasma Panel is bad. Have a trained samsung tech troubleshoot the set.
