12-12-2007 | | many thanks mini!! the power supply voltages were all within tolerance and I'm now concentrating once again on the drive/output circuit. |

13-12-2007 | | Are you talking about the data on 2SC5411?

or are you looking for a substitute?
It is available from several places like bdent or electronix |

13-12-2007 | | I am a tv tech but i have never take that kind of monitor, with that kind of damage, i have change all the capasitor and the first problem solved that is the second one .
If someone have ever that kind of pro it could be usefull, thats why you make a |
13-12-2007 | | There is no direct substitute link I am aware of.
In general , if you are looking to sub any transistor, you should look for something close or higher in breakdown, package/ voltages/toff/ton/etc. there is no "magic" list. It can be very c |
13-12-2007 | | Not familiar with the specific monitor but , sounds like it may be a "thermal" issue? ---may be try using a component cooler on the circuit?
In general, the "no signal" message is triggered when there is no video synch detected &a |
13-12-2007 | | Maybe i was not explicit , the problem is not that says <no signal> but the picture goes down (black)after flashing .
when the picture is black i disconnect the PC and appears <no signal> maybe some dry joints or proseccor internal fault ,b |

if someone has it please contact me |
14-12-2007 | | Suspect the jungle IC. |
14-12-2007 | | I replaced the STKs with 150s, but when the TV is turned back on all I hear is a clicking noise from the left component board like it is trying to turn on? No picture or sound. |
14-12-2007 | | That is actually refered to as "Super Cap" .---Panasonic called it "gold cap"
It is a high value capacitor that was extensively used on majority of brands and is constructed just like watch batteries in series in a package.

14-12-2007 | | Dead pixels on CCD or LCD are common ..even more as the unit ages. I am not aware of any physical repair procedure other than replacement which may still have some.
If affecting the actual picture, it can be easily remedied by software.
