I am getting 7 blink error on panasonic tv.The sc board seem to be problem i ordered repair kit from shopjimmy and did not fix my problem.I also jumpered sc test connector and turned tv see if board would give me a error gave me 7 blinks.I assume if board was good it should have not blinked.any help would be appreciated.

I expect SJ will be getting regular complaints as they sell these kits. Of course the common out will be that the kit fixes most but if you go to my 5081 thread, just had a conversation with someone about no 30F125 IGBTs and the schmitt inverter which I can almost guarantee will be dead with all 5081 shorted SC2 failures.
Hopefully nothing has popped with your powerup attempt. Hopefully you can sort it or I cross paths online to help (fingers crossed)Last edited by tw2005; 05-15-2014, 04:12 PM.Comment

Re: Tnpa5081 af 7 blink error trying to repair
After reading your other post tw2005 30f125 igbts has i short and it took out Q661 and probably took out some other components.I will try to hook up my leakfinder see if i can figure out where my other shorts are at.still trying to figure out how to use it got it a few weeks ago.Comment

Re: Tnpa5081 af 7 blink error trying to repair
Scmitt inverter and Q818 could definitely be a culprit as I found out after numerous failures with the board. From now on, on every board I will replace them, even if, especially Q818 looks innocent in cct. D702 was included in the kit, also read ok, but since it is connected directly to always shorted HA inverter, would be safe to replace it too

I've already highlighted all the bits involved including the 5V reg in the other post. just a matter of being patient and thorough. I'd recheck all previous replaced parts too.Comment

Re: Tnpa5081 af 7 blink error trying to repair
I will replace those items and check see if anything else is shorted.As far as Shop jimmy kit i think they truthly believe there kit will fix the problem but like tw2005 pointed out they probably did not test the kit to make sure it would fix the problem.Or did not test enough boards to make sure it would work properly.I can not speak for every one but i contacted them and told them there kit did not work.There response was are u sure it is the sc board and not main board or sm board or panel they could also cause 7 blinks.I told them i was sure the sc was they problem.They immedaitely refunded my money.I hope they take your advise tw2005 and include the parts that are missing and do more testing.Because this could make a good kit if they would get it right and it is reasonably priced.Comment

Re: Tnpa5081 af 7 blink error trying to repair
I checked ic 771 and it is shorted out not sure about q701 and q702 them i checked them out there is no low resistance also i checked ic773 and pin 5 and 1 are showing .2 ohms i would assume this means ic is shorted.Comment

Re: Tnpa5081 af 7 blink error trying to repair
That being shorted is one reason why the kit failed, not included so that was short even before you worked on it, that is why Q661 is dead again.
Short should clear with IC773 removed, IC771 supplies it.
IC771 is that in the kit?Comment

Re: Tnpa5081 af 7 blink error trying to repair
so I guess your just waiting to source the inverter ic and 30F125 + the RJP63F3A.
Have you got any 2009/10 Samsung boards worth scrapping?
I know the 42C450 series have RJP63F3 transistors on the Ymain, could be some Toshiba too .Comment

I have been trying to solve the power-down 8-blink red LED problem with my Pioneer.
So far I have replaced the power supply board, and the digital assembly board, I have reconnected the ribbons to all boards, ensuring the connections are good. Even though the problem is the 8 red light error and not the more common 8 blue light error code, I had Kcrownie,

by nervxYears ago my tv gave a 7 blink code which turned into 8 during diagnosis. I had ordered a replacement ss board but somehow the tv started working again and i never used the board. Now a week ago my tv flickered and shut off at random and gave the 8 blink error code. The same issue it had all those years ago. The only difference this time is that over the last few months there has been some purple and green tinge that comes and goes in more solid colors such as white.
Anyway i checked all the screws and replaced the ss board with a known good one and still got 8 blinks. I saw a... -
by cheeky2For anyone interested just repaired this Sony Main board TV that had a 2 blink error code, the chassis is a RB2G which is common to quite a few different Sony models. The Ceramic 10uF 25V X7R 1206 capacitor C9114 was shorted which took the smd 2A 0603 fuse out F9101. This was powering the Buck converter TPS54332 which caused no 5V output from it.
See the attached picture of the locations of both components. I also attach the best service manual I found for this board for anyone else in a similar position of trying to repair this main board. It's not specific to the TV model however it gives...01-08-2024, 05:56 AM -
by Superbee_dadHello Sharp TV experts
Our Sharp LC-80LE642U displays one short one long flash error code which is a backlight error. I went into service mode and there were 8 lamp error counts recorded. I reset the count to 0 and did a reset. The last monitor error cause was 16 B00014639:12. 16 is the code for backlight error. I tried to power the tv up but went back into error mode.
