Re: Sanyo - dp32640 - No Video, Green light on, Back light on.
I have this same tv someone just gave me... Light green when hit power button, I can't see any backlight but can see a quick blue flash up top from behind, Looks like around the tcon board.... Green light stays on till I hit off button...

Re: Panasonic 50VT30 , Blinking 7 times.
I had a 65" with 7 blinking lights and only one buffer board shorted out and shorted out a bunch of parts on the SC Board... All the boards fixed mine...Leave a comment:

Re: SAMSUNG LN55C650 Power Supply ?
Has the normal on sound it makes when you plug the ac cord in... Turn on the tv and it blinks 5 times and no light, but all boards seem to be powered up... No video..... When you turn it off it makes same sound and light stays red , which I think is normal....

Re: Samsung LN40C630 won't turn on
The boards in that TV looks just like the ones in my Samsung LCD Model LN55C650 i'm working on.... Just the little quick sound its suppose to make when turned it on and off' all the boards are powered up, no backlight ....
When my tv is turned on, it blinks the red light 5 times and all the boards are powered up and the red light goes out after the 5 blinks., no other light on....When I turn it off the red light stays solid.... Haven't found anything yet.....Leave a comment:

Samsung LCD Model LN55C650
Just ran across this Tv... When you turn it on it makes the little sound, and flashes red 5 times like it is coming on... No video.... After the 5 flashes and the sound the tv is still powered up it seems but no light at all after the 5 flashes.... When you turn it off ' you hear the sound it makes again, then the light stays red....

Re: Panasonic TC-P65S2 Red Light 7 Blinks
GOOD NEWS! Installed the 2 SD/SU buffer boards and TV came on and has flawless picture.... I did go back and swap between my old boards, and my SD board would work with the new SU, But when I tried my old SU board with the new SD board, the TV wouldn't turn on, just the relay click and back off again... So SU board must have been the root cause of all the problems... I just stuck both the 2 new boards back in and it still playing...
Next project' I guess I will try the repair kit on the SC board......Leave a comment:

Re: Panasonic TC-P65S2 Red Light 7 Blinks
One thing I did notice, after unplugging the tv ' the heatsinks on the SU board were a little warm/normal, But when trying the SD board only, then un plugging the tv, those heatsinks were still cold.... I got 2 boards on the way...If all fails I will just put the SC SD SC boards up for sale.......Leave a comment:

Re: Panasonic TC-P65S2 Red Light 7 Blinks
I tried with the SD board only ' SU board removed....nothing on the screen but red light on front stayed solid... Then I tried SU board only and still nothing on the screen...
Looks like option C ----> c. purchase hopefully a used working SD/SU set.
Cause if its the panel , it won't be worth doing any more to it...
With the red light staying solid, do you figure the SC board I installed is working like it should ?...Last edited by colormebad; 01-07-2016, 12:28 PM.Leave a comment:

Re: Panasonic TC-P65S2 Red Light 7 Blinks
Ok' I removed the 4 gnd screws, unplugged sc41 sc46 sc42 plugs.... Jumpered SC50 , Tv turned on and stayed on, solid red light on front... If i try the SD only with SC50 jumpered, do i reinstall the two gnd bolts in that board only? And do i leave the ribbon jumper SU11 to SD11 connected between the two buffer boards??
Man' I wish it was just the SD/SU buffer boards causing the problem... I seen 2 new ones at a good price....Leave a comment:

Re: Panasonic TC-P65S2 Red Light 7 Blinks
I replaced the board with the same board...Here is the new board... I had my fingers crossed it would fire up.... But just heard the relay click on and then back off... I read somewhere just one buffer board would do this, but everything checked out good on the test I done...

Re: Panasonic TC-P65S2 Red Light 7 Blinks
Well I replaced the Sc board today I ordered.... It's suppose to be a new board out of a broken screen tv never turned on... Still have the 7 blinking lights. I rechecked all the same parts on the new board and nothing shows shorted... When I turn the TV on , I here 1 or 2 relay's click , then one more click... That's all it ever does...
Should D503 on this board read something ??? I get no reading at all....I pulled it out and its just like reading a blown fuse or open resistor , even with reversed leads... Then I ran across...Last edited by colormebad; 01-06-2016, 04:33 PM.Leave a comment:
