36afx61 vert problem

On my schematic it shows a break in the foil and a circle around this area marked sl04 does this mean it should be soldered together because it is and it looks pretty sloppy

Re: 36afx61 vert problem

What is the vert problem? Usually, a break in the foil indicates separation of ground planes, but they will converge to a single point somewhere. If there is solder that ties the planes together, this may suggest that someone has modified the board. Again, what is the problem with the TV?

Vertical problem

• Check the Vertical IC foil path for possible cold solder joints

sample guide:

Standard Televisions

• Check the sorrounding components, oscillator

( on most it is embedded on the jungle IC )

• These symptoms can be from dried or open capacitors

resistors, Vert IC or both

• Check for voltages on the supply pins, some have negative


• Look for on-line datasheets most of them are free.

My television, a jvc 21 inch shows only half-screen or at times just a bright line in the middle, what could be the problem and can it be fixed ?

Yes.This tv problems it is pretty easily repair,tv have a cold soldering in a vertical IC or around that area.But must have a soldering iron and a roll of solders and know and have some basic soldering skills.Take the tv aparts and turn it on take the plastic end of a screw driver tapping arond a vertical IC or around that area.Find out the vertical IC or around that area.Turn the tv off and resolders that vertical IC or that area,will solved this problems.Or take it to the tvs shops tell them the problems.If they're give u fairly priced for a job.Like about $25-$35 maxs.

Tv cuts off then after a few min it comes back on or if you tap on the front by the RC jacks it will come back on. It does this several time a day.

Your problem is caused by dry joints and cold solder on the board. If you have a soldering iron and soldering lead open the back panel of your tv. Look for dry joints around the board especially on the power supply section.Cold solder is hard to spot, it is necessary that your working area have sufficient source of light or you may use a table lamp.
Hope it may help you.
Have a nice day!
Thanks for using Fixya.

The TV has a thin horizontal line across the screen. Sometimes the line has color and sometimes the line is white. Everything else seems to be working (i.e. sound, channel changing, game hookups)....

you have a vertical output problem,take something insulated and prod around board and see if pix starts to flutter,then you could have a "cold-solder" joint,otherwise its more than likely a capacitor between the vert driver circuit and the vert output circuitry,

Look, replace all capacitors around horizontal transistor, if dont work, adjust eprom.

Vertical output problem

you probably just need to resolder the vertical output IC. It will be mounted on a heat sinc. probably 7-10 pins. Part number may start with "LA" like LA7845 or similar, there are others though. You will probably see the rings around the solder joints on the bottom of the board. Good Luck

You have a cold solder connection on the vertical output IC or in the sweep power supply that feeds the voltages to the vertical output IC. You can download a service manual from here: Good Luck

You have a bad vertical output IC, or the sweep power supply that drives the IC is bad. Your going to need the service schematic diagram and the know how to fix solid state electronics.

Fixing horizontal line problem

If hitting the set gets the vert to come back then you have bad solder connections on the vert. outputs.. If it dosent then your gonna need to measure the voltage first on the vert output IC see if its about 24 or so volts If it is replace the IC. If its not the replace the vert B+ drive capacitor off the flyback xformer. If you cant find these things then your gonna need to get a schemtic from sams photo facts and post the vertical section and I will tell you or assist youin this repair. If you have had experience in soldering and curcuit work your already ahead in the repair. post the schematic.

Picture squnches into a thin line in center of screen

this set is known for cold solder connections on the vert output as well as the b+ supply line comming from the flyback xformer that supplys the voltage to the drivers. It could also be the vert output capacitor, The two waveshaper caps in the predriver stage of the vert, the filter cap off the flyback or the vert drive b+. Without going in and getting a schematic it will be hard to say. sets like that unfortantly these days are throwaways. NO NO NO dont throw the set at me I did mean that way!!! Its the cost factor of repairing getting the parts as well the the service diagram. it all adds up.
