TEAC LEDV32U83HDR(takes awhile to come out of standby)

Re: TEAC LEDV32U83HDR(takes awhile to come out of standby)

was probing the filter caps and I popped a fuse.
Found out that

DB2 diodes RL206 is reading 0.0 in both directions
and the same as above with
DB3 diode RL206 jgd

would this be all I have blown?

what can replace these.

i would replace your battery in your multi meter and retest the voltages you are testing on dc volts?

Re: TEAC LEDV32U83HDR(takes awhile to come out of standby)

I tested the diodes on diode mode.

They weren't reading like this before this fuse popped, I was getting how a normal diode would read.

Also the tv set now pops fuses thats why I suspect this diode bridge rectifier circuit

What can I use to replace this diode can not find a source for it any where.

Remove the parts and them them off the board.

[Amraks]

Re: TEAC LEDV32U83HDR(takes awhile to come out of standby)

removed from the board the diodes tested 0.00 in both directions.

Do you have DIGIKEY?

Yes we have digikey

OK, then.

34 dollars to ship 10 of them to Australia :O

looking at element14 now..

Since it is standard 2A 800V, do you have any scrap boards that you can look to see if there are something you can use that have the same or better rating?

Re: TEAC LEDV32U83HDR(takes awhile to come out of standby)

I have a heap of computer psu's. I don't mind scrounging for parts as I get these PSU's all the time.

Seems there is holes for a bridge rectifier could I use a bridge rectifier?

also would this one here suit. as I just priced elements postage and handling 12 dollars.
where as RS is free of charge.

Anyone know if I can use the HER207G to replace RL206

I am unsure seems its RL206 is standard recovery and the other one is Fast Switching.

Re: TEAC LEDV32U83HDR(takes awhile to come out of standby)

hey got the tv working again ordered the ones budm suggested.

Ordered 30 of these diodes and some common capacitors and a few 3.15 amp through hole fuses.

Got them off element thought I would make the postage worth it.

But what shocks me is they will send out individual post bags if they haven't got them in stock.

So some capacitors came first, the next day capictors and fuses, Friday the diodes came.

No wonder the postage is 12 dollars when they are doing that.

Re: TEAC LEDV32U83HDR(takes awhile to come out of standby)

Tv came back again.

You turn it on light goes green. No LED's come on.
so I shined a torch on it, up on the right in the center it is showing "Scan"
Then another box showing numbers and pecentage that is increasing below.

Next i turn tv off and give it a shake, the tv turns on like normal.

what should I be looking for here. cold solder or loose connection?

[Amraks]

Re: TEAC LEDV32U83HDR(takes awhile to come out of standby)

Oh also a box that says DO NOT POWER OFF

[Amraks]

Re: TEAC LEDV32U83HDR(takes awhile to come out of standby)

also voltages are higher when this fualt is occuring.

[Amraks]

Re: TEAC LEDV32U83HDR(takes awhile to come out of standby)

check over for loose connections and bad solder joints.

Noticed.
I will try detailed this.
When tv is turned on the light will go to green and the screen will stay black.
Using a flash light you can tell there is something displayed on the screen.
"Do not turn off" "Scan 1 - 100%"(loops)

standby voltages
CON2
PIN 13 = 17v(on the schematic it says 12v)
PIN 12 = 17v(on the schematic it says 12v)
the rest are normal

when tv is on they are normal


Where to go from here anyone have any idea's?

Re: TEAC LEDV32U83HDR(takes awhile to come out of standby)

sounds like a mainboard fault as in stuck in update mode not sure why it has a black screen though does the menu button do anything at all? can you do a factory reset?
