18-08-2009 | | Put you own 12 volts on "there" and see if it works. Electrolytics can still be bad but don't look bulged. :wink: |
18-08-2009 | | A lot of this job (electronics troubleshooting) is "educated guessing." With the limited information that's available for these products, this is sometimes the best you can do. Without testing each component in the suspect area, you cannnot rule |
18-08-2009 | | Model? :wink:
Analog/Digital?
With or without a DTV converter box?
Tried doing a rescan? |

18-08-2009 | | Hi, if you are indeed right then i think you will find a lot more damage to your equipment than a blown fuse.
In the struggle between god and surge protection (even if you had one fitted), afraid there is only one winner. |

18-08-2009 | hitachi 53f300, dp25h chassis. deflection board problems | I got this tv from a friend after it quit working, I have replaced the power pwb, and I have replaced the flyback as well as all the IC's that are on the heatsinks on the deflection board [b:e46391ee79]except[/b:e46391ee79] the convergence IC's.I also had |
18-08-2009 | | Ok, no? |
18-08-2009 | | It's either the digital main board 6HV0016910
or the tcon which has no part number available. |
18-08-2009 | | Resister so I can send you a pdf for troubleshooting. |
18-08-2009 | hitachi convergence | ok, I registered. Thank you for your help.

19-08-2009 | Convergence problem | I have a convergence problem before and I replaced both cirucit stk392-120. After I replaced I do not have video and audio . Any suggestions I am good soldering and I can read the multimeter but I am not good reading circuit. i think one capacitor or one |
19-08-2009 | | I found a picture of the board online. This board is selling for $180, but the same caps that were bulging on mine also look suspect on this one. I wonder if someone can look at this and give me an opinion on these capacitors. They're the two large ones, |
19-08-2009 | | Having seen it before, I can tell you that they are OK and more likely the same with the capacitors in question on your board.
The subject of "bulging capacitors" is indeed valid and rather a common failure however, it is mainly observed with l |
19-08-2009 | | Just to make sure we're understanding each other...
Set had convergence symptoms (but was working);
You replaced STK's;
Set now doesn't work (No Video/No Audio)?
If I have it right, there must be a connection. You unknowingly may have done something |
19-08-2009 | convergence problem | Thank you for the response
Like you said It was working before I was missing the green color (misalignment). I changed the ic twice the first time I changed with an equivalent circuit. and I have the problem and I replace with the original number. I ch |
19-08-2009 | | here is a data sheet for the stk392-110/stk392-150 equivalent built by NTE: http://www.nteinc.com/specs/7100to7199/pdf/nte7178_81.pdf It should be enough to at least get your pinouts and voltage ratings. Regards, Jason |
19-08-2009 | | check the little led lights on your power board. are all of them coming on, and is the red one flashing? when you power the set up which light turns off first? this will tell which circuit is causing the problem. Regards, Jason |
19-08-2009 | | replace the vertical and the convergence IC's while your at it. I buy mine from http://encompassparts.com/ . Regards, Jason |
19-08-2009 | | Check the leds on the power board and post back with which ones are on and off when you turn the tv on. Regards, Jason |
19-08-2009 | Information regarding transistors N1117 & N1212 | Hello,
I pulled out two transistors from an electronic balance which I think are defective but having trouble identifying their correct specifications. The markings are N1117 and N1212. In my opinion the full part number should be 2N1117 and 2N1212 (plea |
19-08-2009 | | Hey...
Thanks all....the guides provided by you all worked nice for me and i just successfully disassembled my laptop. I have just successfully replaced my damaged LCD and for that thanks to you all. |
