    Have the same problem here with the same appliance model, where can I buy the vertical chip, I believe this chip is somehow new? and I believe the chip should be exactly the same as the "original" and not just some replacement.

Roy replace the vertical ic with original or second hand ic because mostly of the brand new parts in store is defective.

My compaq monitor just start blinking and now only haft past of the screen is visible. the rest just went black with on bright shining line on the middle of the screen


hi,
Your monitor have problem with vertical deflection section. Can caused by the faulty vertical driver IC and faulty electrolytic capacitor it the vertical section or dry soldering in the pins of the vertical driver IC. When vertical section fails horizontal lines come on the screen. For testing the same you have to open the monitor and remove the main board. you can easily find out the vertical ic. just follow the four wire running from the deflection yoke ( coil on the crt neck) of which two will go to the horizontal section (normally red and blue wire) and two will go to the vertical section ( Normally yellow and green wire). Follow the yellow and green wire which will be connected to one of the socket in the main board. Follow the circuit track in the main board which will lead you to the vertical deflection section. There you can see one ic is fitted on a aluminium heat sink.Take a close watch in soldering of its leads. Dry soldiering can happen in its leads because its a component which will got to a temperature about 75 degree above at its normal working condition. if found any dry-soldering or not just resolder all the pins of that ic. then check the monitor. If problem remains then you have to relapse the ic.While replacing the ic try to relapse all the capacitors in that section. It will prevent from any further damage to the new vertical ic. if you need any more assistance feel free to contact me through fixya

Tv has horizontal lines on top of screen.


Hello
You are seeing vertical retrace lines on the top of your TV screen.
There are mainly three causes for it. I don't know the age of your TV. The first cause is due to the supply voltage lack to the video output state. You can check it on the picture tube base card. You haven't mentioned about the diamension of your TV screen. So it can be say as a guess. If your TV is 27", the voltage mantioned above will come to about 245VDC. If there is a great voltage loss, check the smoothing capacitor to that supply, will normally come to the value of 10MFD 450V.
The second one is, capacitor related to the vertical output stage of your tv. It is in the circuit board. Normally these capacitors are situated in an area, which will get hot during working. As s result, there is a chance to the value change of their capacitance. It is best to replace all of them, as it may not cost too much. Before desoldering it out, mark the value of each capacitor is best. Normally replacing the filter capacitor 3300MFD or so,to the power supply to the vertical output Ic will solve this problem.
The third is related with the vertical output Ic itself. Just check all the soldering points in the vertical output section of your tv board. Anyway, resoder all suspected soderings by applying a little more solder, as bad solderings to the legs of the Ic or some other components also may the cause. OK.

If this is a tube type or crt type. Your vertical circuit has a problem. Could be the vertical IC loose connection on its board. Or the vertical ic itself is faulty. If just resoldering or refluxing of its pins doesn't help check some minor cmponent within vertical circuit. Or the vertical ic is defective already.

If your not inclined on electronics never do the repair itself, nasty voltages might caught you.

hi there, is the single line horizontally or vertically? if horizontal line, you do have a vertical section problem, check some parts at vertical section, the vertical ic, the power source of vertical section ie diode & resistors. ty

Missing vertical deflection on philips TV


TDA 8362B IC which have vertical freq.output is at pin no.43. (vert.osc) caution for fixing this problem minimise brightness to avoid crt burn. proceed as follows 1 if you are getting sawtooth at output of ic tda 8362 pin 43 then check 1 supply at vertical output ic from eht. 2 yoke connector loose . 3 check vertical output ic parts. 4 finally vertical ic. please check for normal output from power supply even though fault gets rectified just for protection. good luck.
