Vizio E701ia3 No Video
Customer submitted this nice Viziuhoh to me yesterday and he claimed he had a red blood like run in the middle of the screen (6" from bottom ) and he quickly turned off. The TV came with no display after and only sound was heard on all inputs. He replaced the Tcon with no change. I purchased a main just as an outside chance it could be but that too to no avail. I have heard these have panel issues and when testing the screen boards I noticed the right side kept giving me short readings on the caps. Would it be feasible to change those caps or is this a lost cause? I also thought of purchasing a Tcon myself and only hook up the left side which appears to be fine ( no shorts are present ). I think he either received a bad Tcon or the screen itself is a goner. There are no voltages past the Tcon. The problem is..did he buy a bad Tcon, did the screen take out the Tcon or something else? Thanks for any input and I would put pics but didn't see where any was needed but if you have interest, please let me know and I will be happy to do so.

Re: Vizio E701ia3 No Video
I have the same model set in my shop now. 12 volts on t-con, no heat on any IC's replaced t-con, and main. NO change. I called Sharp as this is a Sharp panel, ( I am authorized Sharp service) they said panel have customer call consumer relations. ??? NO way of finding the actual defective component? IF you find what is on the panel that is causing this please let me know. -

could be the caps, did you measure them with an esr meter?Customer submitted this nice Viziuhoh to me yesterday and he claimed he had a red blood like run in the middle of the screen (6" from bottom ) and he quickly turned off.

Re: Vizio E701ia3 No Video
Just found this Kevinjo<
VIZIO recently issued a statement with new information that in a small percentage of units with serial numbers in the ranges of LFTRNWAN3800001 to LFTRNWAN4805300 for Model E601i-A3 and LFTRNXAN4500001 - LFTRNXAN4702936 for Model E701i-A3, users may experience a loss of video on the display although audio can still be heard. This potential issue appears to occur typically around the first 500 hours of usage or first few months of normal usage and does not present a safety concern.
If you have a VIZIO E-Series 60” or 70” TV with a serial number that falls within the ranges of LFTRNWAN3800001 to LFTRNWAN4805300 for Model E601i-A3 and LFTRNXAN4500001 - LFTRNXAN4702936 for Model E701i-A3 and experience a loss of video, please call VIZIO’s Customer Care team toll free at 855-209-4106 or email us at: special.bulletin@vizio.com to directly reach our dedicated service team who will assist in resolving your issue as quickly as possible.
Aside from the small number of units within the serial numbers ranges of LFTRNWAN3800001 - LFTRNWAN4805300 for Model E601i-A3 and LFTRNXAN4500001 - LFTRNXAN4702936 for Model E701i-A3, there are no other VIZIO products that use this component. See our official statement at:

Re: Vizio E701ia3 No Video
Common issue with the VIZIO led the E70 and the E60 series no video but sound replacing the T-con board or main board is not going to fix it save your money it is an issue withe the panel I just repaired 5 of the 70" and 4 of the 60" and the all work perfect no issues what so ever and VIZIO is aware of that and all they do is replace the unit for customers but a simple repair to the panel can take care of it.Comment

Hello everyone,
I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the... -
Hello everybody!
To put you in context I recently replaced the battery from my HP Pavilion 15 bc400ns with a used one, everything was going good. The same day, I decided to update the BIOS, everything went good. The thing occurred after I let the battery drain iddling on Windows 11 for the second time to calibrate it that the screen did not turn on again, the computer was on but the screen did not turn, like it would not wake from hibernation. I decided to restart the computer but got no video.
The thing is that I had installed TeamViewer and could log into the computer... -
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... -
Hi,
i have a 65 Panasonic TX-65HX710E using vestel 17MB170 main and Lg tcon.
Few drops of water fell probably near COF and have no display. Tried removing tabs but no.part of display present as if tcon fuse open. However 12v is present and tcon can be felt warm enough that supplies are present. Backlight and sound ok.
Anyone knows if this TCon 6870c-0805A has any special test pins for rgb test?
Appreciate your help.... -
I have an HP gaming 15-0013dx laptop , motherboard quanta G3HA with AMD Ryzen 5 cpu and Nvidia discrete grsphics card. The laptop turns on and u can see the screen polarizing on and off in a loop but no video signal. All voltages are ok measured and stable (I checked all with oscilloscope). This schematics don't have power sequence but I'm using a similar sequence from another laptop with AMD CPU and I get all to the point CPU must release apu_pwrok and apu_rst#, this signal comes valid only for the period of time the screen is polarized and they disappear and same loop behaviour (active/inactive)....
