i have a panasonic ct 2701 tv that when turned on it has white lines on the screen that after awhile they go to the top of the screen sometimes therers 2 lines at the top and some times theres four or five lines how can i fix this problem and can you send me step by step pictures of the board and instructions on how to fix the problem the lines seem to be folding the rest of the screen is fine only aboye 1-1/2 to 2inches at the top of the screen has the problem thanks.
There are capacitors in the vertical drive circuit and the sweep power supply circuit that needs to be replaced. If I had a service manual on this set I would be able to tell you what caps go bad. If your not trained electronic techs, its also not a good idea to be experimenting inside these sets, as they hold high voltage, and can give ya a bit of a shock if your not carefull. Also all the parts are soldered in place so your going to need to know how to unsolder as well as solder or you can ruin the Printed circuit board. Please if you have no experience with TV sets seek out a trained tech to assist you. Good Luck and do
how can i fix this problem please help.
Do you know how to solder and unsolder? Do you have a capacitor checker? Do you have a schematic diagram? If the answer to one question is no, then I can not help you, as there are certain tools and things you need to know before you should touch a TV set. Its most likly a capacitor as i stated before, but if you dont have the tools, How can you check it for being bad. If you don't have a service manual, you can not tell what capacitor is in the vertical circuit, unless you look and test every capacitor that has the same prefix as the vertical output IC. You can't tell, without being experienced, where the vertical IC is. Sorry my friend there is no quicky fix for this set.
Theres no picture my freind, Do you have a schematic? I cant tell by a visual. I need a schematic diagram to see how the circuit works. This is like when your check engine light comes on, you need a diagnostic tool to see whats bad. I need a schematic to go throu the circuit.
no i dont know where to get the schematic diagram
i could not wait any longer i took the set to the repair shop three bad caps and changed the ic $75.00 not bad but i would of liked to fixed it my sely but could not find the repair guide nor skymatics thanks for the help.
Thank you so much for letting us know. I looked for this service manual for days and could only find it as unavailable anymore from panasonic.
panasonic model-th14z2.. trouble, vertical hold, cannot stop..
there are bad capacitors in the vwertical circuit
pls tell about trouble of t.v. panasonic model-th14z2, trouble- vertical hold cannot stop.
sorry ai do not have a schematic on this set. you will need to check all the vertical capacitors with an ESR type capacitor tester meter
I have a TV it shows lines on top of screen. I know how to solder and unsolder. I have a tester, pliz help me how to test for capacitance. pliz help.
your assitance be highly appreciated.
THANK YOU!
you need an ESR meter my friend, a special capacitor tester they run about 145 bucks or so. A standard cap meter or multimeter will not test them correctly
I got a memory stick and want to put pictures in it but I can not get it to download. I know you copy & paste but it want let me. What am I doing wrong? Thanks Jan.
is the computer seeing the memory stick???after you insert the stick go to my computer to see if it is listed as a d or e drive could also be a f ora G drive depending on how many drives you have.

I have panasonic th-14Z2 tv and it just only lights the LED if turned on.. I guess its ic str has problems.. is it right??
