SUMMARY
======
This is a SANYO DP42841-02 made in 2012/02. I get no audio, just a little bit of static from the left speaker (as you face it), no sound from right at all. Video and backlight are working.
DOCUMENTS
======
Z5VGE SERVICE DOCUMENT says to use Z5VG as the only change is power on led position change--ATTACHED
Z5VG SERVICE DOCUMENT split into 2 parts for 2mb limit--ATTACHED
If there is a manual, do ya'll still want pictures?
THINGS TESTED
==========
I used a Fluke 87 V to check all of the connectors marked on the power supply for the voltages specified as printed on the board. The first two digits before the decimal were correct to the markings of 24v, 12v and 5v
On page 35 of the service manual it asks if there is signal at the speakers. I'm ignorant and don't understand how to "measure" signal. I bought a logic probe in case thats what I needed.
I didn't want to make anything worse using the wrong tool with it powered on.
With no power connected to the tv and the speaker connector disconnected from digital main board so not to interfere with the measurements, on IC001 I did measure the resistance between pin 24 and pin 30 (left speaker) and got 2.8M (upside down horseshoe symbol) The right (pins 21, 15) was 0.805M (upside down horseshoe symbol). I read somewhere, can't find it again, that its suppose to be "not shorted" or below 4M or IC001 is bad.
PROBLEM
======
I have little/no knowledge in/of electronics. I need help figuring out what/how to test next to make sure I'm right. In all the Sanyo threads I've read, there seems to be an issue with the 13v audio power. Is it possible to test for this even if the IC001 is bad?
QUESTION
=======
If IC001 is bad, how does one replace it? Can a novice/noob do it? What tools would I need?
