What voltage do you have with the meter probes set to DC placed across Pins 1 & 2


Only one of the administrators can change a Post Title or contents of a post.

8.7V volts,


administrators made the changes already.

What voltage do you have on Pin1 of IC6802 and chassis and then on Pin4 IC6800 and chassis?

I did replace the component, still the same voltage on pin 1 and 2

What part number did you replace it with?

Replaced with 2561A, same part and then EL817


IC6802 -> PIN 1 = -0.23V
IC6800 -> PIN 1 = 0.01V
IC6800 -> PIN 3 = -0.01V

Thanks!

So the opto's should not be the problem.

Can you check that IC6800 Pin 5 is at 12V and IC6800 Pin 4 is at 9V

They are 0 Volts.

How can I check if CXA3809M is switching? IC6501
CXA3809M => IC6501 => Pin 20 => 10.2V

Looks like the IC is not switching on with 10.2V



I do not see any voltage at T6101 Pin5.

Its 10.5V, you must be right, Why is the 12V not turning on

Re: Sony KDL-40EX710 - Lightning strike and power surge

I have replaced the IC - CXA3809M => IC6501

Now the RED LED lights up and I have a 3 blink error code.

Can somebody help me please.

Ah!! looks like the whole TV is bad... Checked the voltages again, There was no power going into the TCON board.. I jumped 12V to TCON now the Error code goes to 7.

Looks like a shot TCON Board. I am not sure what else I would have to change.. Is it worth changing it?
