Symphonic wont turn channels
I just received a free 20" Symphonic LCD TV (WF20L6) it didn't come with a remote so I have to use the menu buttons on the TV to navigate through the setup. I got to the channel setup and it only goes from Video 1, Video 2 and then skips to channel 60 and that's it. The lady who gave it to me said it was broken but didn't say how...so i'm assuming this is what she meant. Any ideas? There is no Channel 3/4 switch on the back so it's not that.

Re: Dell WebPC mouse problems
Yes it does and it is enabled.....I can only boot in safe mode and then I have to navigate using the keyboard, the cd-rom drive is absent in safe mode so I can't install drivers that way.....there is no floppy drive nor an empty bay to put one in and it uses 3 usb ports and NO ps/2 ports, in safe mode no usb devices will be detected if plugged in so I can't use my external floppy drive either....

Re: Dynex DX-LCD32-09 Sound but no Picture
Yes that's pretty much it....there's just the one cable going from the power supply to the inverter. Let us know if it works!...

Re: Magnavox 32MF231D/37 Fixer?
Yes those caps are shot.....I did use the Panasonic FM caps but it didn't do any good....not the caps fault, there just appeared to be bigger issues at play. I never did fix it, it's still sitting in my storage room....

Re: Dynex DX-LCD32-09 Sound but no Picture
I powered on the TV last night in the dark and nothing....not even a little flicker.

Re: Dynex DX-LCD32-09 Sound but no Picture
The problem I was having with the inverter was when the inside of the TV was put together, the Mainboard sits OVER the inverter....covering the half with the power connector. So when tom66 was trying to help me, I had to keep removing this board and that board in order to test.....then put it all together again to test something on the power board. Most tests came back ok. As far as checking for a quick flash when powering on....I think I tried that already and saw nothing, but i'll try again tonight when it gets dark, and...Last edited by gorr35; 09-14-2011, 02:00 PM.

Re: Dynex DX-LCD32-09 Sound but no Picture
Is there suppose to be a decimal somewhere? If looking at the previous inverter picture....from left to right. Tested p4 to p5 on each transformer.
@2000ohm setting - 970,987,989,989,982,982,988,997,980,985,986,994,999,973....

Re: Dynex DX-LCD32-09 Sound but no Picture
Not sure if this makes any sense the way I posted it.
From pin 1 - p2=1, p3=002, p4=1, p5=1, p6=1
From pin 2 - p3=1 p4=1, p5=1, p6=1
From pin 3 - p4=1, p5=1, p6=1
From pin 4 - p5=975, p6=972
From pin 5 - p6=002...

My meter doesn't have a 2k ohm range....did you mean 20k?Re: Dynex DX-LCD32-09 Sound but no Picture

Re: Dynex DX-LCD32-09 Sound but no Picture
The person who game me the TV didn't tell me anything about it other than that she got up one morning and that's how it was. As you can see from post #7 - there is nothing on the underside of the inverter. Both fuses on the inverter test at .09. As far as the transformers....there are no numbers on them, just the numbers next to them on the board - T304 etc....

Re: Dynex DX-LCD32-09 Sound but no Picture
2 seconds to black never applied here as the picture never comes up, not even for a split second, but I know what you're saying.
Retested at the 20k setting and #5,11,12,13,14 are reading 1....all the rest are reading 0.00...Last edited by gorr35; 09-12-2011, 11:48 PM.

Re: Dynex DX-LCD32-09 Sound but no Picture
I tested the transformers at both 200 and 2000 ohms and here's what I got (pictured)
BTW: I did do the light trick in front of the screen and I do see a faint picture....Last edited by gorr35; 09-12-2011, 03:16 PM.

Re: Dynex DX-LCD32-09 Sound but no Picture
I'm OK with testing most parts, but I have to admit i'm not real familiar with testing Transformers on the inverter board....can someone tell me the correct way to test these things? As you can see in the picture, pins 1-4 are on the bottom and 5-6 on top. Do I set the ohm setting to 200? what multimeter probes go where? What numbers am I looking for? Is it better to remove them from the board to test them?...

Bypass LCD TV Inverter Board Shutdown Backlight?
"How To Bypass LCD TV Inverter Board Shutdown Backlight System" Has anyone seen this article before (Below)? Has anyone tried it? Sounds pretty dangerous to me. Supposedly it is to check to see if your CCFL Lamps are out when you get sound but no picture, or if it's the inverter board itself. Do all LCD TV's have a similar chip with the same functions?

Re: Westinghouse TX42F430S 42" 1080p LCD TV
Pictures of the boards would really get you better and faster responses....you may feel that because there are no physical signs of failure that pictures shouldn't matter. The people who want to help you can get a better understanding as to what the layout of your TV is, as they are not all built the same. Just trying to help.

Re: RCA STB7766G1 Digital Converter Box
If it's a closed captioning box then the tv nor the converter box are not set up for it...i checked the settings.
EDIT: Plus there is no text inside the box....just blank.Last edited by gorr35; 09-06-2011, 01:24 PM.
