Re: sony tv image scrolling
i thought the same thing bout i couldn't get the panel to react differently by pushing on tabs. i guess i would just put this on hold till last, since i have plenty of other panels to fix....Leave a comment:

sony tv image scrolling
I have a sony tv the image is scrolling across the screen from top to bottom. I suspect that it is the Tcon Board. am i wrong in this assumption ? -
Re: 40EX521 is blinking 6 times
sounds like a power board to me, just repaired one that had the same symptom by replacing the PSU, i didn't bother to do component level because i had another screen that had a bad tcon board.Leave a comment:

Re: LG 50" PK540 Plasma Clicking, not turning on.
i did a the same test with the diode and saw "that problem" and when i took it out of circuit it tested fine, i doubt the diode is bad...Last edited by ijchan223; 08-06-2014, 05:28 PM.Leave a comment:

Re: samsung PN50C450B1DXZA
i replaced both the x and y the panel and got magic smoke from around the y driver , i don't see any obviously blown component however i smell it . i am going to guess it is a shorted panel.Leave a comment:

samsung PN50C450B1DXZA
Hi , i am working on a PN50C450B1DXZA when i hit the power button the screen flickers once but doesn't come on. The power supply will stop delivering power to the logic board after a few seconds, if i don't short the pins to turn the tcon board on. The tcon board and the y buffer board has been replaced from supposedly working parts. The next board on my list would be the x and y sus boards, would either of those boards cause the psu to turn off , like a disconnected tcon board?
Also how do i know if the panel is shorted out ?Last edited by ijchan223; 07-20-2014, 03:57 PM. -
Re: samsung ln46c670m1f won't boot
Update: i replaced the logic board and it works fine. out of curiosity, i will attempt to do some component level troubleshooting and repair on the board. More than likely the micro-controllers are dead from a lighting strike or something, but you never know till you actually look into it.Leave a comment:

samsung ln46c670m1f won't boot
Hi, i have a samsung ln46c670m1f that won't boot just a solid red led. i have done some visual troubleshooting and all the caps appear to be good and no obvious fried components.
tested voltages with the main board disconnected the black light would come on and all the voltages check out on the connector but with the main board connected the standby voltages (at CN8 ) seems to drop and cycles on and off at a rate of 1 hz. to me it appears that there is an issue with the mainboard but i am new at troubleshooting a tv so i would like some input before i spend money on it and it be... -
