SANYO AVM-3289G no vertical deflection

I have a SANYO AVM-3289G with no vertical deflection, just a vertical line and audio. Can you please tel me which transistor is the the vertical output on this set? I have ordered the SAMS photofact, just would like to order the parts also.

Re: SANYO AVM-3289G no vertical deflection

It isn't a transistor, It will be an I.C. with a part number that probably starts with an LA_ _ _ _ . It will be on a heat sink and be in the vicinity of the connector going up to the yoke. Try replacing that. But first, check all the electrolytic caps around it for testing dry (sorry - takes a special meter to do it in circuit) or just replace them. May have lost power to the I.C. as well. Look the I.C. up in the free NTE crossreference at get a diagram of its pinout to find what pins the power and outputs are on.

Tv goes to straight line in center of picture then

It happens when Vertical deflection stops as Vertical Out IC becomes hot or does not get vertical signal.
Please check electrolytic capacitors and dry solder joints in vertical out section in TV.

We have perfect sound but only a thin horizontal line in the middle of the screen.

this is a capacitor that has gone bad in the vertical delfection stage of the tv. it is an very easy and cheap fix if you know someone who knows how to solder and replace electronic components. If not then you'll just have to get another tv as taking it into a tv repair shop is not worth the cost. You could get another tv for what they will charge you to repair it,

Vertical line in center have replaced vertical output ic

If the line is vertical then the problem is no horizontal deflection. The vertical chip is probably fine.

Check connections around yoke (thats the connector with at least four wires that goes up to the coils around the neck of the tube)

Maybe that TV has two horizontal output transistors. One for deflection and one for high voltage? Check both of them. Look for bad solder joints!!!

Vertical line in center

If the line is "vertical" then the vertical circuit sounds OK. The problem would be in the horizontal deflection.

Check yoke connection and solder around horz defl circuit.

If the line is horizontal then I would suspect the vertical IC.

Avm 3259 picture problem

Vcc is on Pin 6 of the vert. output IC so you can trace that back to it's feed resistor (not sure the location number but you can find it easily by following the circuit trace). Depending on what your problem is you may need to replace some electrolytic capacitors as well. Follow pin 7(pump up) back to it's electrolytic cap. and look for swelling or bulging. Look for other bulged capacitors in the vertical section. You may also identify a bad resistor by a discolored look but not always, if in doubt meter it.
Let me know if you need some more info.

Thanks for your help,

Probably Horizontal output shorted, you would need to check the 3 leg transistor on a heat sink to see if shorted.

Sanyo DS31590 31" TV vertical deflection

If the vertical is not defective or shorted there is a possiblity of bad solder connections on the vertical ic. If connections are good and has b+ voltage to the chip replace chip which is IC 501 LA7841 or LA7845 and change c511 (decimal point 1 film capacitor)

Sylvania vertical deflection problem

I don`t know where you live and it makes a BIG difference, the cost of doing business is waaay more in NYC than Peoria. At my shop if you brought it in, approximately $110 plus tax (6% here in Fl.) I`m basing this on the fact it needs the output IC, you may not need the IC it`s possible the 26 volt line is missing to the IC but you asked for a generic guess and that`s what it would cost you here, remember: Big City means big rent which means much higher bill, I`m in a little town in western Fl. hope this answers your question, good luck

Sanyo 25" Standard Tube Vertical Deflection Problem

you can proceed as follow to fix it.

  1. reduce brightness to minimum to avoid screen burn.
  2. check voltage on vertical uotput
  3. check yoke connector for loose.
  4. check v/yoke winding.
  5. check v/drive from signal processor to vertical output

now your problem how to find out whether drive is there or not it is very simple even you donot have scope.

you simply touch with screw driver or meter prob  at the poibt where vertical signal is input to vertical stage

if h/line is spreadindg or tries to spread then your output is ok &problem is in drive ckt.

for schematic try given site give model no &download it

hope this will help
