Re: Sony KDL-46EX700

this is what you told:

and so i answered..
the persistance of 6 blinks is either bad strips or bad backlight circuit, but i guess is the first, so why don't try the same my advice?

Thanks...I tested the strips before install and they all worked, so as we in America would say: I assume they are good.. So now I need to figure out, per your advice, how to test the backlight circuit that you mention.

I am a novice to this, although I have experience in computer repair. I am also reading a Sony Training Manual: AZ1L Direct View LCD Television Chassis Course: CTV for ideas,

Thanks

Re: Sony KDL-46EX700

6 blinks was not bad LEDs for my Sony. It's bad power board. I tested all lights before removing and they all worked. I replaced anyways because of comments stating it's bad LEDs. New LEDs all worked and still 6 blinks. It states power board for my TV. My TV had 2 power boards. I would look more closely at that because this advice led me astray also.

Says most likely power board or panel. Then says replace main board. This is for 900f though so I'd look into that. The new problem you have well I don't know. Just do due diligence into PSU checking

Re: Sony KDL-46EX700

A normal backlight tester is not good enough to test leds with small leakage, if you think i'm saying stupid things i don't know what to do, if you want my help you can simply follow my advices, testing a psb is not as easy as my test.. anyway if you know the ohm's law and you are rich in power resistors arsenal you can put some and simulate the leds, hoping you have psb specs

I appreciate your assistance, I DO NOT THINK you are saying stupid things, never said that or inferred it!

I'm very handy, but know little about the actual fine testing methods you describe.

Thanks

Re: Sony KDL-46EX700

Did you check over your solder joints?

Yes with a magnifying glass and as best I could tell, all looked good.

Re: Sony KDL-46EX700

So new used board is in and all works, except I messed up one of the LVDS cables that connects the TCON to the screen. Any ideas where I can get? Do I need a Sony or can this type flex cable be gotten (and made) from any electronics store?

[nomoresonys]

Re: Sony KDL-46EX700

Should be a number on your cable, put that in search, maybe try ebay.

Could not find one:

Re: Sony KDL-46EX700

OK so I just got this part number from Encompass: 1-837-704-11

Re: Sony KDL-46EX700

No luck so far, is this something that can be made?

[nomoresonys]

Re: Sony KDL-46EX700

Can you show a good picture of the damaged area?

Re: Sony KDL-46EX700




The corner got bent over.

Re: Sony KDL-46EX700

So it's a lvds cable that goes from tcon to mainboard NOT tcon to panel driver board, probably best to get a replacement, not sure what models are interchangeable.

It goes from the TCON to the screen.

Ok, hard to tell from the picture.

Re: Sony KDL-46EX700

TV is now repaired. Was able to source an aftermarket cable from an eBay seller in China and the used board from here in the states.
