Horizontal black line and picture goes up and pull it down full
I have a Philips TV Model No. 32DW6557/05. The picture horizontal alignment moves up leaving a black 2- 4 inches margin. The picture moves back again fully every time when tv turn it on picture go up. Am I correct in assuming that the Horizontal Synchronization Circuitry is the fault ? If this is the case, -pls can any one show me the location of Horizontal circuit board, and what is cold solder connection are and whereit will be and how can i repair it. any help will be appreciated

it could be that the tv convergence circuit is going bad. One shure way of finding out is to go to the tv feature menu(picture,audio etc.) and select the customer convergence setting, you should get a cross hair pattern(cross in middle of screen). that cross should be white and by aligning the red or blue colors they should move left, right, up or down
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.
If you are using original cartridges then there should not be a problem. The horizontal lines come from the cartridge. Can you pinpoint if it is a color or black line that is missing? My guess is that during the alignment procedure, you are asked to choose a number or letter that corresponds to picture of a the lines that show the best alignment. If you did this correctly, may I ask how many pictures you printed before seeing that line. Is it on the first print or 10th printing? Cuz if it is on the 5th or more full color picture, then the problem is that you you really have the wrong printer. The F380 capacity for printing full color pictures is miniscule. 1 ml per color. So usually after the 3rd color picture, the ink starts to run out. Let me know if this helps.
now only visible in a thin horizontal line.
first of all you reduce brightness to monimum.
it just to protect your tv from crt demage.
your problem is in horizontal output section as you have mentioned that week or so ago the right and left bottom edges of the picture began to move in like a sideways triangle filled with black so this sympton is due to hor. section problem.
your flyback transformer or horizontal output might be defective.
but remember check for power supply is ok from
hope this will help.
Sounds like you have a power supply filtering problem. Perhaps a filter capacitor is going bad. If your set has a switching power supply
oscillations from it are getting into the video.
You need to have a tech to check it out for you. You should get an estimate first before having it repaired.
Sounds like you need go this site, enter codes and re callibrate your TV to the settings.
If this does not work - then sounds like you need tv repair man replace caps or solder bad joint.
