slide 96

the only combinations involving SC20 removed staying on which is the same as removing A20 are:

A20,A32 - TV stays on

A20,A31,A32 - TV stays on

A31,A32 feed to the C boards

Re: Panasonic TCP-42S2 6blink

tw 2005 I ran the test u mention with all cables hook up and remove C10 connector and sc20 and I did get 8blinks .

also I checked the voltages on the blue caps on C 633 I get 51 volts, facing the caps on right leg same for C 632 no power on the left leg ,
On C413 the smaller blue cap I have 205 volts on the left leg and no power on the right leg .

All these voltage are measured when power up and before going to the 6 blink.

All the transistors and diodes i got from outsource and found some of the parts were defective right out of the shipment .some diode were dead no reading .

Also I have check the voltage on SC board

TP 82= 15.2 V
TP 99 = 0 V
TP 46 =0.11 V
TP 101= 0 V
TP 102 = 4.95 V
TP 3 = .30 V
TP SOS = 4.23V

If there is any thing comes to mind for me to look up just give me a shout ,I may look into getting another Sc board ,Just may.Thanks for help

If TP SOS6 4.23V(I assume since you have neither 6 or 7 labelled) then the SC is faulted. On initial start up it goes high momentarily then low, if staying high then it's faulted.

Which parts were faulted from UT ? I have not had any dramas yet, touch wood.

If you only get 53V on the bank of blue caps, that's bad. The ER circuit isn't charging them up. You can check the SS board for a comparison of what the voltage should be.

Ok guys I finally got this tv going I bought a used SC board on line , the board was supposed to be a for parts or repair , After the board arrived I started to check out all the fets and diodes ,they all checked out good, put the board in and start it up , it started right up and been running for the last three days.

Here are some test results from checking the transistors and fets :-
+ indicates red lead on multitester
_ indicates black lead on multitester

those results from working or not working board? Q601 you have at 2 and bit ohms?

Those results are for a working SC board tw2005
