SOURCE: vertical deflection

The problem may have been caused by the Vertical Filter Capacitors located in the immediate area of the deflection chip. If this is the case, and the chip you replaced was bad, you may infact, have another bad chip. You need to check for a shorted capacitor before rechanging the chip again. Good Luck

Hiii...

My version is :
For safety reason you should replaced them ( Horizontal ic,Vertical ic, Deflection ic) and olso all the big capasitor nearest the ic....that's my version....if you have big budget for it....he..he....

Thank's

SOURCE: unit has sound, no vertical deflection. caps and

If there's an audio,,it might be the defective Vertical IC...but check first if there's 24v-26vdc supply coming from FBT going to Vcc of Vertical IC.

If there's no Audio,and only white horizontal line in the screen,check the Vertical out of Jungle IC.

Good luck!

Why come white vertical line on my t.v screen in center?


You said "I checked vertical output line from main ic pin 23 found correct"

But the problem is "Horizontal Output Line" Try that.

Hi, I have a Tedelex EC29187 Television it have only a horizontal line in the middle of the screen, I opened it and looked for physical damage around the vertical defflection IC, but it show nothing so...


Ur tv it is taken aparts wright now?Yes.Plug in ur tv to see the problems and take the hard end handle of the screw driver and taps around the vertical deflection ic for cold soldering joints,will require resoldering the ic,if the vertical hold flickers or bounced back to normal.No bounce back vertical hold check all the sorrouding capacitors transistors resistors for dead components parts to be replaced,if all the sorrouding parts are good,than that vertical deflection ic it self it is dead and require replacing.

Horizontal ine in CRT tv


Failure of the horzontal linerity coil, possible dry soldering on the board of the components- resistors and capcitors- in the horizontal coil circuit . Also failure of the deflection coil- YOKE- in the crt. So check the coils and the circuit around this section as the rest of circuit seems OK.

Panasonic tv. model no. TC-21-FJ20R the power is off the IC SRTW 7754 the 300v is still on it


Panasonic TV TC-21FJ20R is a big blunder of Panasonic Company, shame for Panasonic company to launch this type of product in a huge price.

My Panasonic TC-21Z88RBN doesn’t displays the total picture vertically ,when the picture is display it like not in the center of the screen sum of it is disappear in the bottom


Hello

Your TVs vertical output section has the fault. You just open your TV after disconnecting it from the AC mains wall socket, and locate the vertical output section. This section uses an Ic marked as part [IC 401] on the board and its number is LA7840. Just look for any loose soderings around its components legs, and the solderings at the IC legs, which has 7 of them. The IC stated above will be screwed onto a heatsink to radiate heat out of it when it works.
If all soldering point are fine, come towards the IC legs and measure the voltages at each leg. The voltages must be
pin 1= Ground
pin 2= 12.6
pin 3= 24.7
pin 4= 4.4
pin 5= 4.4
pin 6= 24v [vcc]
pin 7= 1.8
All voltages stated above are DC voltages with respect to ground. If any of this voltage is missing, find out the reason for that. If all of them are noted abnormal, IC may be defective, and replace it.
[vcc] stands for main input voltage to the IC.
If you need any more assistance, feel free to contact me through Fixya. Ok.

Vertical Deflection Squached 85% Picture ok.


Not knowing what brand or model you have, I would say you need to replace all capacitors around the vertical output ic and resolder the vertical output as well.

I have a three year old model pvc2542 tv/vcr combo the picture is just a line in the center of the screen


Bad vertical deflection circuit, unless you have a bad connection (bang on set to set it it fills out for a second) . you will need components replaced such as the IC, capacitors possibly a fuse from the power source to the vertical IC.
If its a bad connection soldering the IC pins is not to hard if you are OK with taking it apart yourself.

Vertical length


Hiii....
I think you should check the cap around ic vertical deflection.... and see if there is have adjustment point or not ?! if you not so sure try to replace the caps and the ic too....

Vertical Deflection problem


i also suspect its just bad solder connections, the vert. o/p ic is maked ic451 look for all the ic's on heatsinks. it should have 10 to 15 pin all in a straight line & be attached to a small heatsink. if i remember right i think if you are looking at the tv from the back it is on the left side near the front (by the buttons/swtitches). resolder all the pins on the ic & resolder the parts just around the ic as they too also develop bad solder connections. just remember to check for shorted pins after soldering. good luck.
