SOURCE: No power

The D1541 is a horizontal output transistor, not an IC. Your problem is definatly a bad flyback transformer.

Resolder the vertical IC and replace those capacitors near and next to your vertical IC. If the horizontal line still appears, you may have to replace the IC. Thanks for asking and be caredful!

Problem with panasonic ct27g5b, flyback transformer secondary volts too high changed str58041 but power supply only make whining sound when turned on


Check all the components in the main power supply board, including STR switching device, for any damage, or loose solder terminals. Check and replace the damaged component. Check the horizontal output transistor too, for short. Check it for collector to emitter, or collector to base short. It will be best to replace it with a new one, and check.

Panasonic TV - no picture, but sound is ok


resolder flyback transformer contacts on the board, if doesn't help, replace flyback and horizontal output transistor

Picture shrinks horizontally every few seconds.


You are changing parts in the wrong circuit. The problem is in the vertical circuit. Look for the vertical IC and resolder the pins first. It should be an LA7837 or something similar. Also, check the 100ufd and 47ufd caps in the same circuit.

Keep us posted.

Keeps blowing fuse


It has a short circuit somewhere...
Not sure if this is a CRT, LCD or Plasma TV but the two common causes of shorts for CRT's are the Horizontal Output Transistor (HOT) and/or the Flyback Transformer (Could be both). As a general rule if the flyback has visible cracks in the case they should be replaced. It is also a good idea to replace the HOT if you're replacing the flyback as it could be weakened and may not last much longer itself.
Other areas to check for all types would be any Diodes in the Power Supply Circuit. If a diode is open it can cause the fuse to blow. Note that a diode itself will not short, but an open diode can cause a fuse to blow.

Tv went dead


Sounds like it could be H.O.T which stands for horizontal output transistor or a fuse is possible. Another possibility is the FLYBACK transformer. Is there a local repair facility you could take it too? Keep me posted. Have a good day...Jay

Panasonic CT-27D30B


Put a voltmeter on the vertical I.C .
pin 1 should be 12Vdc
pin 2 should be 24Vdc
from those two inputs, it should be generating at least 50V on pin 13.
If those are not present, trace the power back to its source in the flyback circuit, where a resistor or diode has blown.
If present, check its output on pin 12 and if there, trace through the vertical output circuit.
If not, it may not be getting a trigger pulse from the main video chip.
Hope Ya Fix It!

TV does not turn on


I'm looking for the same info... my CT-32sx12f is completely dead too. I was wondering if the IC regulator or the flyback is bad. Fuse is fine. Anyone have any wisdom or experience on these sets they can interject? Thanks!

3year old Panasonic ct-32sx12f dead?


Sure, Why not? It is worth the effort. If the set is 'dead', it is the easiest to repair.Only 'tampered' sets pose problems. It could be a simple blown Fuse, or the Power Regulator IC. This should not cost you more than $100-150 as Technician charges + 15-20$ for spares. It could also be a defective Horizontal Outut Transistor and short cicuiterd FBT, (tho' it seems remote), but if yes, add another $100. definitely worth calling a professional techie
