Re: visio 27" tell me what you think
Bad caps or cold solder joints, the ESR of the bad caps may have gone down so the TV starts working again.Never stop learning

Visio E601i-A3
Tv powers on and input is able to be selected/used, but the on screen menu closes as soon as it is opened and the there are some periodic "glitches" of the on screen menus in relation to position and size. I have tried all the system resets,but because the menus are not usable, i was unsuccessful. Does this seem like a panel issue? Odd that it only affects the menus and not the main input picture. I have already tried disconnecting front panel buttons assuming one was stuck down causing the input to continually be scanned or similar.

Hey everybody. I'm curious if any of y'all have experience working on older arcade or pong games. I was recently contacted to help fix up what I believe is a 6 Pac I retrofit board by Venture Line that's integrated into a third party cabinet (Tennistronics?). The unit is old school. All 7400 logic, 555s for timing, and so on. No microprocessors in sight.
The unit's in surprisingly good condition, but has an issue with the 3rd player paddle. It seems that the paddle will always extend from the bottom of the screen to where it ought to be, it's about normal width if you move it to... -
So... I have the patchy back light issue with my Visio M70, meaning some light up, others do not. I finally got around to testing the LED driver board and found that was not the issue (swapped another one in and the same issue persisted) and I am considering if i dare dive deeper into this TV and go after the LED strips.
Right away i see that they don't seem to stock them anywhere out there (E700DLB0016-002) is a part number that i see a you tube / seller guy list out. He has a nice video of how to get into my exact TV out there: https://www.youtube.com/watch?v=0AcUPiN83Tg

No backlight issue. Have sound and can see menu with flashlight.
Suspect LED driver, voltages are 100V each side. What should the voltages be for 75 inch TV on the Power Supply Board? I have 96 leds x3 volts per=288/2=144 volt per side?
Am I low on my volts causing the leds not to light up?
Before I got all backlights out, the right side was a bit darker than left side. How many leds
need to be out for all to not work?
Thinking of getting a led tester. If leds light up, would that confirm it is the Power Supply Board?
I do not want... -
Its been a long time since i been on here.
Anyway i searched the model number but no threads on this issue
I pulled this unit out of my companys electronics recycling bin
Wouldnt turn on so after opening it up discovered 2 bad caps
Replaced the 2 caps harvested from a different psu which where the same brand and rating .
I only did this to determine if the unit would power up which it did.
it has a vertical black bar and I dont recall if the issue is due to a bad tab bond or a faulty chip.
Is this repairable or should...
