On the other side of the circuit board where the pins are solderd to the circuit board. Be very careful soldering the pins because if you bridge the pins together with solder you can damage your set badly. i would recomend just heating the solder thats there to reheat it and not add any more unless your skilled on soldering with pins located close to gether as you can damage the set worse if your not careful.

Sears 32 inch bright horisantal line across screen maybe 1/4 in rest of screen black have sound

Hi, bronco, my name is John. Welcome to FixYa. This could be the horizontal output transistor, also called HOT. It also could be cold solder joints that need to be resoldered where they have lost connection or contact. This is a easy fix. If you have some soldering experience. Remove the back from the TV, the HOT is located on a flat aluminum piece. It will be a three leg (pin) transistor with a screw at the top of it. Make sure the TV is unplugged, slide the circuit board out, on most boards will be held in place with screws. With the board solder side-up and with a desoldering iron, remove it and the screw. You can order parts here . Give them the number off the transistor. You will need some heat sink compound when replacing the transistor to the shield. Thanks for choosing FixYa. Good luck.......John

Intermittnet picture, sometimes part of the verticl

Cols solder connection on the vertical output IC.

Be careful - when you pull the chassis it pulls the plug that connects to to front logic and it takes careful eyes and a flashlight to put it back in.

Red screen, horizontal lines, 2'' black vertical bars both sides

it looks to me that you are not a technician becouse you are measuring at the wrong places risking a hazard shock if you have a little experience get the service manual and check your power supply and the h v capacitors near the horizontal output if not please take it to your service center

Not turning on

take your tv to the w/shop,
fill the tempreture of your verticle ic, test it, if too hot, remove and put another one.
also test a capacitor, eletrolitic near that ic and feeding a verticle scan coil.
this will solve your problem, ok

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.

Zenith model SR3587 Picture too wide

there are a couple of coils that are for pincussion and width that get cold solder connections on them and sometimes will blow out the curcuit. Maybe its not to late to resolder them? Good luck
