There is a circuitry problem with the scan control, this is a job for the "Shop" as I always advise get a firm "Quote" B4 prceeding with any fix... Generally these days there is no Horizontal/Vertical Hold, as such, it is all done by the Compter Chip inside.

I have a Vizio 42"

Since you have multiple problems, I would inspect the power supply module first.
It can be power problem, main control board problem, etc, it needs in-depth troubleshooting.
Basic troubleshooting guide here:
Failed TV and Monitors pictures:
Learn about bad caps:
Capacitors kit: he can make you a set of caps.
Or just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

Pictures and type appear elongated and not in proportion. appear to be squeezed together. how do i make adjustment ?

There should be buttons on the front of the monitor which will open up a menu so you can change the horizontal and verticle adjustments. You will first get a menu, figure out how to move within the menu selections, select the horizontal setting and move it move the image more out to the sides, generally done by increasing the number shown for the current adjustment. The move out of horizontal and go to the verticle adjustment to make sure that is correct..

I hope that this information is helpful and helps you go in the right direction to solving your problem.
If this does help, please leave some good feedback for me.

Power, but no picture

First remove the back panel. Taking special care to loose all the screws. Once the screws are lost take out the biggest hammer you have and proceed to "fix" your TV by beating on anything that hums.

Philips TV Model 32DW6557/05 Screen Problem

hi it sounds like a capacitor in the verticle circuit located on the main board. it is near the verticle ic. the verticle ic also could be bad the cost is around 85 dollars for a tv shop to fix. sometime a cold joint could be found around vert ic. a soldering iron is required with solder.tap the side of tv if picture comes back it is just cold solder joint.

thanks Doctor video

LOL nothing to do with the teenagers as your hoping it is?? LOL It about the life of the tv your talking about to have vert. sweep problems and at this point not a serviceable thing you can fix! As there are no serviceable parts inside these sets and ther is a HI voltage issue you need to know before you start tinkering with a set like this. Its a problem as i said in the verticle sweep circuit and is probably the capacitors in the circuit causinging the problems. Get real and enoy your kids while you can and try not to blame all that goes wrong on them even if it seems it may be from them. They didnt cause this problem!
