Re: Magnavox 32md359b/f7 White Screen and with sound only
OK couldn't resist - got to sleep soon though! Which end of the the board plugs into the LCD panel (it will go up into the metal frame, possibly onto another board) and which end into the yellow/orange boards?Please do not PM me with questions!

No, it's the single flex in the pic...its on the right hand sideComment

Odd arrangment; the other two go to the yellow boards? I'm trying to figure that out, have the bent the cables over for one set?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Magnavox 32md359b/f7 White Screen and with sound only
No the three go to the power supply board and the flex flat cable that is off to right side by itself goes to the LCDComment

Re: Magnavox 32md359b/f7 White Screen and with sound only
Oh OK. That cable is just smaller than I expected for the kind of data but this TV is designed in a unique way.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

There are two flex cables going to that LCD ...One from Inverter board and the one which is shown on the system board in the pic aboveComment

Re: Magnavox 32md359b/f7 White Screen and with sound only
Is the board on the LCD just a long thin strip? I am hoping it might have a fuse, but I don't think it will.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Magnavox 32md359b/f7 White Screen and with sound only
Hmm, you are getting sound, so most of that SupraHD chip is working. I think the only possibility is something on the LCD isn't working right. But they included no fuses... There are some drive voltages, -6.8V, +16V and +22V. These are available on CN1001, which goes to the inverter.
-6.8V is at C202 - a little beige/brown disc probably.
+16V is at C201 - similar
VGH is pin 10 (22V) or possibly Q201 (one pin should measure 22V, the other, 24.4V, and the other 23.9V according to schematic.)
Please verify these are good and present.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!
My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.
This time the original cable broke too close to the screen, it can't be fixed without tearing the screen... -
Another TV topic!!
I got this sharp TV that when I first plugged it in it showed the sharp logo and then went to the input screen. This was about 30 seconds and then it showed white screen. Now I can't see anything but white screen. This has a separate TCON and Main.
The TCON is getting 12V and several parts are as well but the VGH line is only .5Volts which I thought is totally incorrect.
Am I on the correct assumption that the TCON is bad somehow if I'm only getting that voltage or is there something else I should check?... -
Hello,
I have a Dell G15 ryzen edition (ryzen 5) that turns on but won't post, black screen, keyboard lights on, caps lock led on, fans turns and the battery indicating light is showing 2amber and 1 white according to dell website it's a cpu failure, but i tried few basic things before i open it up i tested the screen by pressing the d button before powering it up but it didn't show anything i tried the ctrl+esc for bios recovery but still black screen i tried refreshing the screen, i plugged it on an external monitor but same thing. Next step i unplugged the battery and kept pressing the... -
I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly ‘new' Tcon board this time, and... -
so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!
what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol! 
i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...
