Re: Sony KDL-65W850A 5 blinks error



I have the solution for the 5 and sometimes 4 blink code!, long story short. A client brought the tv to the shop and said, it had bad image issues, but when i tried to power on the tv, i got the 5 blink code. After making all kinds of measurings and tests, i found nothing wrong, the last thing i checked was the main board, again nothing wrong with it. After puting back the main board the tv powerd up just fine, but after a few seconds i got not the 4 blink code. So i checked the ribbon cable the one that goes into from the mainboard...

Re: Sony KDL-65W850A 5 blinks error

Hi guys, did you know what caused the 5 blink error?, i'm having the same issue, tested PS, and it has all voltages, when powered manualy. I don't think it's the main board, my money is on either the tcon board, or the LD board, i'll keep troubleshooting it, if i find the cause, i'll let you know.

Can't find any for this Model, guess JVC didn't released one.

Hi guys,

Long story short, my Tv, stopped tunning cable frequencies, I started to diagnose the tv, and found out there were 2 caps completely dried up, very high esr, one was a 22uf, and the other one was inside the tunner a 10uf/16 volts one, after replacing them. got back cable frequencies . Bad thing is no l don't have now HDMI. It seemed blocked, so I made a litte digging on the subject and found out that it may be due to a light sensor disabeling the hdmi ports for copy protection of some sort.

I tried accesing the service menu without finding any reset...

Re: Another sick iMac G5 PSU

I'm not an expert, but I would recomend you check first what caused the failure, you might keep burning the TOP245 or damaging componets till you fix first what caused it.

Hi guys,

I have a burned Bestec power supply, the problem was at the IC 8, it shorted due to humidity and burned itself, I was able to see the inscription on top of it and it says, A 635 M, not very sure about the M, and looking at a past thread I saw that someone said that this power supplies had the A6351 pwr chip, so i figured it was the one it burned out on my power supply. But after I reviewed the datasheet I saw that pin 1 is Source, pin 2 is GND, and pin 3 is Vin. Knowing that, before i solder it i saw that on the track where they are supposed to be solder is a continuos...
