Panasonic 25'' 4:3 CRT Vertical collapse.

Hi all, I'm new here so HELLO to y'all! Hope all is good! :-)

I have a Panasonic 25'' PAL CRT 4:3 ProLogic television (TX-25AD1DP). The tube has a vertical collapse.

I know the risks involved with repairing CRT's, high electric store etc.

Would anyone have any advice on how to repair this issue myself.

P.S. tapping/light banging on the case does not have any effect.

Any help would be much appriciated.

Many thanks in advance.

Andrew.

Hi
Please check around vertical outpu IC for bad solder joints and you can try to replace the electolitic capacitors in vertical output line. Check if vertical plug (which comes from deflexion coils) is well attached in place.

Tv on appears black screen with a bright horizonal line in the middle sometimes with voice


You will have to resolder the vertical IC and in most cases replace any capacitor that is near and next to the vertical IC. There may be three capacitors that will be replaced, And while you are in the process of reworking the board inspect for any and all grounds that may need resoldered. You will have to look very close to find these. And you should search the deflection side of the board for two capacitors that have a 160 volt to 250 volts at 1MF, or 2.2 mf or 4.7Mf. By now these little guys are weak and need replaced. Thanks for asking and show a few hands of support!

VERTICAL COLLAPSE WHAT IS THE PROBLEM


This can be as simple as poor solder connections at the vertical Ic to a defective IC. The parts cost for this is usually around $25. There are capacitors in the vertical circuit that should also be checked and/or replaced.

I have a panasonic tv with retrace lines at the topI


If you can locate the vertical IC you are nearby!. You will have to resoder the grounds on the vertical IC and any cap in the immediate area of this vertical IC is weak. I would replace them all as they will pull each other down. There may be four caps and the largest one, possibly a 25 volt 2200MF would be the only good cap. I dont have the specs on this set, but this will surely lead to a good repair!

Panasonic CT-27SL15 has scan lines on top 4 inches of screen, what is problem and how to fix?


Nov 2011 - Comment
Have similar problem on a Panasonic Tau model CT-27SL15.
It's a 27" CRT TV manufactured around 2005.

Other posts / solutions on this problem say possibly a capacitor going bad in the vertical circuitry / near the vertical IC / vertical blanking circuitry. Telephone call to a TV repair person mentioned something similar - "possibly a bad capacitor in the vertical circuitry".
Found a service manual online w/schematics and board layouts.
Panasonic Service Manual
http://dl.dropbox.com/u/35219914/PANASONIC%20CT27SL15.pdf
See pg 25 (of 42) - Deflection Schematic Diagram (Main PCB)
Shows: V Output IC - IC401
Finding the actual bad component(s) may not be so easy.
Anyway ... just wanted to add this comment.

Hello! You have vertical collapse. There are bad solder connections at the vertical output IC. I have repaired MANY panasonic tv's like this. Very easy to repair if you have any soldering experience. If soldering does not fix the problem you need to replace the vertical IC. Good luck

Pal to NTSC


If you bought a converter it would convert 25 frames a second to 29.97 or 30 frame 625 to 525 NTSC no adjustments and thats been that way for decades. You can rent a sony or Aiwa deck with legal converter on board and do this easy. So go and get a real converter!

Tv tube problem


It`s total vertical collapse, which means 3 possibilities, vertical IC has failed, vertical IC solder connections are broken, the B+ line (voltage to make IC run) to the vertical IC has failed. None of these problems are big dollar repairs, 1/2 hour repair by any qualified tech, Good Luck & Happy Holidays, BMW Rider

Weird TV


the audio is perfect, but the screen vertically squeezes to about a quarter of an inch and stays horizontally regular. it is due to vertical section of your tv has failed. it is a common problem if you are not a tech person call tech to fix it. solution 1 check vertical section supply. 2 check components in vrtical output stage. 3 check vertical output ic. 4 loose contact in vertical section it is not a major ptoblem. good luck.
