Re: jvc dvd receiver model # XV-TJD60 only stays on for a second
with nothing hooked up to it I might add. so nothing external is causing it too turn off.

jvc dvd receiver model # XV-TJD60 only stays on for a second
So my new receiver only stays on for about a half-second after I press the power button. what is usually the main cause of this problem? -
Re: 40 "Sony Bravia kdl-40S5100
Actually the t.v. stopped working after one of our close family friends had a fire at their house. The fire/water restoration company couldn't restore their t.v. as their job is to mainly deodorize/clean it. He requested his t.v's back anyway so he could tinker with them. I thought it would be fun to help out so here I am.... It was an electrical fire and the unit gave way to either a surge or from when the firefighters hosed the place down.Leave a comment:

Re: 40 "Sony Bravia kdl-40S5100
thanks so much!! One thing i do know is that there was no backlight coming on when it was powering up. I turned off lights and everything. I'll pull out a 1000 ohm resistor and try to get this bad boy to power up as soon as I can.Leave a comment:

Thanks rmoody!! No, the backlight wasn't coming on at all when the tv. was powering up. Now all the voltages coming out of the big female socket are minimal. all .01-.03. Same goes with the smaller socket that connects to the main board. However, this is with the power off. And yes I'm getting continuity on the big fuse down by the ac inputLeave a comment:

Well, I was testing the voltages from where the socket connects to the main board, i believe and I got all the right 12V, 15V and 3V readings. Then I heard a clicking noise and the green light doesn't even light up anymore. Guess I fried something. oh well, I tried. LOL....Leave a comment:

Also I need to note that the green light turns off when I take out the connector from the power supply to the main board. I figured this is why the only real readings I got were on the three volt standby pin. Or maybe I wasn't grounded to the right pins. Can I keep my probe on any ground pin in the socket? There are some for 12v and 15V. It requires quite a steady hand and I don't want to do any more harm than has already been caused.Leave a comment:

O.k. so I found out my old multimeter was toast. I got a new one that's on the relatively cheap side but was the winner for eevblog.com's $50 range. It's an extech 330. I also ordered the blue ESR meter and should be coming in the mail soon. So far with the nonvoltage detector I get voltage on all the boards and all parts of the board. When I take out the connector to the main board I am getting three volts on the standby pin. Here are some better pics of the boards....Leave a comment:

Thanks, Tom.
As you can tell I don't know much about t.v. repair. or t.v.'s in general. I do have a multimeter . I have somewhat of an electronics background but i mainly when it comes to reading schematics/soldering and applying ohm's law etc. You're info is a good starting point. When I get off work today i'll do some research, read some voltages and get back to you.Leave a comment:

Re: 40 "Sony Bravia kdl-40S5100
Alright guys, I get the message. haha. I have an extremely busy schedulte these days and I'm guilty of lookin for a quick answer w.out doin much research.I'll do more research, post some better pictures and get some voltages as soon as I can.Leave a comment:

40 "Sony Bravia kdl-40S5100
Hello my fellow BadCappers!!!
I have a 40 inch sony Bravia that powers on, green ight stays lit, but there's no picture or sound. There are no obvious bad caps and i do not own an ESR meter. From what I understand this might have to do with the ysus or mainboard. any thoughts? Here are some pics for you guys. There's still a board in the top center that has yet to be uncovered. Not sure which board that is. thanks so much for helping a newbie out!!! The only thing I've ever changed before are bad caps on a power supply and this is taking it to another level for me.... -
Re: line when copying
It is only when copying or scanning. It's a quarter of an inch thick. I can assure you the glass is clean. At first I thought it was an issue with calibration because the black strip covering the calibration strip on the glass has been worn down by someone using abrasive cleaners (white is showing in some areas of the strip). Looks like it's a sensor or something with the optical train. What can I do? Hopefully I do not have to order from the overpriced HP site. haha. thanks again!!Leave a comment:

line when copying
We have an hp color laserjet CM1312nfi MFP all-in-one printer up at work. When ever I copy something i get a line on the left side of the document. Any advice as to what the problem may be would be much appreciated....
