Re: Sanyo (No Power) DP26748

Diode 1630 >- .777 M ohms I went to check it again, and it flipped across the room somewhere.. LOL

Diode 1633 > Three Prong.. one Closed (OL) and the other says 11. Then, rechecking it again, one of the prongs fell off; it's useless! everything checks OL now.

D601 > .633/OL
D670> First Test: 69.8 Kilo Ohms Second: 56 Kilo Ohms

LOL! I sent a .6mm resistor flying the other day... glad the Mrs found it on the carpet! LOL

The prong fell off????? Pics please

Re: Sanyo (No Power) DP26748

Resistor had no resistance .. OL both ways.
I tested it in circuit and then took it out..

Re: Sanyo (No Power) DP26748

I don't have pictures, I threw that diode away. Couldn't read anything on it.

Re: Sanyo (No Power) DP26748

STill no video .. no back light neither..

[Keshetisrael]

Re: Sanyo (No Power) DP26748

I took the video board off, checked the back of the board.. no blown problems visible..
Put the board back in, plugged everything back in, unplugged Tcon and then plugged it all back in.. Now I get the BackLight.. but I can't get Cable, or Menu to come up..

Re: Sanyo (No Power) DP26748

I'm thinking the TCON Board isn't working too..
Is the TCON what houses the 'Menu' program?

[tom66]

Re: Sanyo (No Power) DP26748

T-con has nothing to do with menu. Main board does menu.

[Keshetisrael]

Re: Sanyo (No Power) DP26748

Is there some way you could help me to narrow it down to a component on the mainboard? Something I could switch out?

In a way I could learn why I'm doing it..

I read that Tcon board will give a No video scenario.. if the TCon isn't working.. will the 'menu' appear?

Re: Sanyo (No Power) DP26748

ok with the backlight now working, check the voltages at K6R again

Re: Sanyo (No Power) DP26748

Here is pics of the video board.. what part gives 'onboard' menu? -<><

Re: Sanyo (No Power) DP26748

Like Tom said, the Main board gives you the Menu etc.

I applaud your wanting to have a deeper understanding but just follow their instruction and perhaps they'll give you the logic as they go along.

::::Side Note; A Personal Regard :::::

Well.. I am reading everyday more.. and being I am a property manager, I'm given the time to work on all my skills so I can make a living from doing this. I love working on things and electricity has become my God's theme, in my life.

I worked as an electrician's helper for 4 + years and now have a computer repair business in Clearwater, Florida working out of my duplex. I have a couple small websites I've done for a couple people that I host on Hostgator, and I'd now the only thing that I can see helping me to sustain my drive for 'knowing', is Knowing! So, I want to know everything; no matter how vain it may seem to think that it's actually 'one day' possible.

If you need to know anything and ask me, how can I not tell if I've the time? I hope other's are just as willing!

I'm also a Priest (since 1994) born through the cross of Jesus the Christ. Hitchhiked 14 years of my life, spending about 7 of them actually on the Highways between states going from Churches, law libraries and Soup Kitchens to Rainbow Gatherings, Festivals & Hot springs; before settling down in this duplex called, "little IsReal".. the only Real Little Bit that I got after all these years! I'm 42 now. Anyways.. I appreciate all the help I can get.. I know that when I don't know something that you 'really want to know' it becomes an insatiable passion until you know! It's not something your angry about, but 'meaning something', at times you will appear 'mean' or even 'Mad'! Don't let 'em get you down! ROFL -Namaste & Shalom

Backlight on yes?

Check voltages across K6MA (main to driver connector)

Re: Sanyo (No Power) DP26748

Not going to believe this.. I talked to the guy that owned the TV after getting the powerboard and that wasn't it; he didn't want to fix it anymore feeling it would cost more than the TV is worth..

So.. I left it for a while then one day I opened it up again. I left it without the back on it for like two days, putting it in one of my computer chairs one night, the cat jumped up onto the chair in the middle of the night and the TV fell off the chair, right onto it's back!

I picked it up and left it for two days figuring the thing is for sure Broken now. Well, before just throwing it out.. I decided to plug it in one more time and I got sound and fuzz!! Still can't get menu to pop up.. but static sound and snow in the picture!
My cat did better than me!

Well, there is no 'menu' button on the TV, I guess you have to have the remote & of course the owner never gave it to me. So.. I'll post more when I find out more.. Namaste & Shalom
