Re: Sanyo TV stretches outwards and shakes
If the picture is closing (top to bottom) and goes back to normal when you hit it you probably have a bad solder connection on IC501 (location number) the vertical deflection IC on a metal heat sink. If you mean outwards as in side to side as it looks in the picture, I don't know specifically where to solder but get a magnifying glass and look for suspected bad solder connections. Look for the word width if it is there. It is good that you a confident in soldering.

There is no picture tube in a modern flat screen TV.
And unless it's physically broken, it's usually something else that has failed and not the screen.
A picture tube is a CRT (cathode ray tube) that sends electrons from the back to the front to light up different color phosphorous dots.
A modern flat screen TV on the other hand is LCD (liquid crystal display) that turns on and off to allow backlighting through multi colored filters. (LED TV also uses a LCD screen, the only difference is the backlighting is LED and not fluorescent lamps.)
You've got the BRAND, now we need the MODEL and NUMBER!
And maybe an actual question would be nice!
There are a few "flat" tube TV's but very few that were made several years ago. The vast majority of flat screen TV's don't have a picture tube.
If the screen is physically broken on your flat screen TV it's probably not worth the cost of having it fixed. If it's not physically broken, something else might be wrong.
a model 58D33 is a LCD screen not to be confused with an LED tv , aas LCD tv displays use a std fluorescent tube for its back lite source and yes they do burn out eventually , unfortunately these tubes are not a user changeable item and tv needs to be disassembled to install a new one
Usually to change the video format of your tv you will find it in the remote control try to look for format button in your remote there you can change the different aspect ratio of your video format settings. hope this help good day and best regards.
There is a problem with the board of your television.That problem is in vertical section, theres a leak capacitor at the vertical section of the board.Its better to replace all the leak capacitor to make the picture back to normal appearance.If you can't do the repair or replacement of of capacitor try,Call a repair technician to do the repair or troubleshooting..Thanks..
Hi my name is Roety,
I can help you with your issue ,
There are a few buttons to adjust the picture size on different make TVs and even on the Cable/Satellite remotes .
First look on the TV remote, set it to Full ,Fill or Just or 16 x 9 (whichever your model uses) Samsung uses the P size button ,
Then on the cable/dish Box remote stretch (not zoom) is usually best.
On the box remote set the output resolution to 1080i only
And use 16x9 when if offers a choice.
Cable remotes use the # key as a zoom/size button.
Due to the fact there are 16 size/Formats available (3 or 4 being transmitted now). you may have to hit the zoom/stretch button on some HD channels.
But with these settings the picture will mostly stay full and help you avoid image burn from the edges being not on the edge.
Stretch will fill the screen and allow you to read the bottom.
Make sure you are on the correct input, sometimes TVs are connected on multiple inputs
(not necessary, only the HD input is needed)
If I have helped you with your issue
If you have more questions you can still respond
I will reply asap
I have the same problem, my television is faded black on the left side with lines on the left top side. I have had the 46 inch unit for 1 year and 7 months. I am planning to write a demand letter to Sanyo and then taking them to small claims court woth evidence that this is a common problem with their units that they know about and is not trying to remedy. Also the Attorney general in Texas should have an interest in them (Walmart and Sanyo) selling these defective proucts in the state.
