Hi,

Appreciate the "Ask Me".

I am assuming that you have more than just familiarity with electronic components and circuitry, the use of a DVM and a soldering iron. Further, that you have access to a service manual.

Width problem is basically insufficient horizontal deflection, then analysis would have to be in the horizontal section. Areas to initially focus on:

  1. 12V line and pin 29 of IC401;
  2. 110 V peak to peak at collector of Q403, if yes check Q 402 & 404 as well as T401;
  3. other components that affect the horizontal size are:
  • IC201
  • Q 405, 406, 407 & 408;
  • D409
  • L401
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

The problem lies with some points on the circuitry which have came off the circuit board. Solder it after replacing with a spare similar to the original.

Obviously you have a problem with the horizontal deflection circuit. try replacing those 10uF capacitors on the horizontal circuit. Look it up on the schematic diagram if you have one.

What is cost of yoke for panasonic ct tv?


You're discussing about the width problem to picture. If yoke have a short in between its wingdings [even a single winding short], will cause the failure of horizontal output transistor. As per you report here, the set has a raster, but problem is with the picture width.
There possibliliites for this fault are.
1. Lack of voltage from the SMPS power supply output.
2. Horizontal width capacitor.
3. Horizontal output capacitor.
Check the output voltage from the SMPS section first, and confirm that it is OK.

Width problem


A width issue specially if this is short of width on the screen can be due to many reasons:1. It can be a low +B which means the SMPS power supply has a lower output due to low Switching or a low value on the main capacitor. Check this out, measure the +B on the mains end and also the secondary side which will confirm.2. If the secondary +B is correct the fault can be with the sync circuit IC or the horizontal coil or even a fault with the deflection coil. A proper measurement of the voltage in this section is important.3. Check for weak capacitors and DRY soldering on the horizontal section , line output section.

I hv lg 700s studioworks crt monitor... i hv set a resolution of 1280*1024, but now m not able to control some of its functions like its width size...width has gone out of the monitor, it isnt getting


Hello
Select reset option by monitor menu, set it to default first. Then try to adjust the width and height of the screen. If this does not help you, try other resolutions set by the system.

Screen horizondally pulled right side and screen rolled to left side


hi,
your monitors horizontal deflection side have some problem. you have to check the horizontal width cotrolling transistor mounded on the aluminum heatsik near the lot( line output transistor). also check the three mosfets which adjust the width for different resolutions. there are three such mosfets in the horizontal section.

fist of all replace the width controlling transistor in the heat sink. photo of mosfet and transistor is added for reference. not the exact number.

Above is a manual link. usually you use multiple presses on the buttons to get to the menus. One button, is menu, the others are for up.down & left/Right. The same as for Horz Posn. You press the menu, use the L/R buttons to go to the menu item, then up and down to + or - the setting.
have a look at the manual.

Monitor width is out of screen


Check for shorted transistor, shorted diode, leaking/dried capacitor it could be ceramic or electrolytic. Look for some shunting diode or capacitor that is connected about horizontal size/width ciircuit. Leaking, shorted or open can make horizontal size shrink or expand.
