first of all - this refrigerator has a control bd that drives an inverter board that controls the compressor. The voltage coming from the inverter bd driving the compressor is 80 - 230 VAC. 1. test the compressor windings - should ohm out all the same. If all the same ohms between the 3 pins - compressor is probably good. 2. test the control bd by testing for 4V-6V volts going to the input of the inverter board - this is the voltage that drives the inverter board to put DC voltage to the compressor. Also test for 120 VAC going into the inverter bd. If no 4 VDC - 6 VDC voltage going to the inverter...Last edited by ajshoe; 10-01-2024, 08:09 PM.Leave a comment:

LC-60E79U backlights come on - bad video
Have a SHARP LC-60E79U LCD tv that powers on with distorted video and backlights on. Is this T-CON bad or possibly PWB not supplying voltage to it ? Haven't taken back off - thought someone might have seen this problem before....

after searching for new edge led strip, no parts available - seems this company is defunct now. scrapping tv. NOT WORTH FIXING. anyone need main or PWB, let me know.Leave a comment:

LeEco L554UCNN no display
Looking for someone that possibly has worked on one of these Intertek sets. L554UCNN super 4 X55 LED tv. set turns on - -no display. backlights seem to light up but not fully. Also set will not turn off after turning it on with remote. measured CN8601 and CN8602 led connectors.
CN8601 has 82 V and CN8602 has 27.4 volts. thats between pins 2 - 8 on the connector. Its very hard to get to the pins as its double sided. using a flashlight - nothing on screen. feels like LEDs are bad ? is there a schematic available to see LED pinout ?
update - after examining the led conns (CN8601...Last edited by ajshoe; 01-13-2024, 08:30 AM. -
just got 60PK540 - same symptoms. check PWB - had bad C360 and C361 (3300uF, 10V). easy fix, set works perfectly now -
Re: Vizio D55-F2 backlights won't turn on
many vendors are confused on this main board. Have to go by the bar code as this is where the part # for the main board is. 75500w01b001 is for the 65" version - 75500w01c001 is the 55" version. The 75500W01C001 will not work in the 65" version as 4 of the 16 led strips will not be lit.Leave a comment:

Re: vizio E60-E3 backlights, sound, no video
your post #6 states to unplug TCON cables - you didn't read post #1 cause I did unplug TCON cables to display and test. Again the display tabs on the bottom are bonded to the board. so I'm still at a loss at what your asking. The only way to fix this set was to remove the LEFT side tabs. I did this and the set is repaired.Last edited by ajshoe; 04-09-2023, 09:55 AM.Leave a comment:

Re: vizio E60-E3 backlights, sound, no video
I did unhook Tcon ribbon cables 1 at a time - read first post.Leave a comment:

Re: vizio E60-E3 backlights, sound, no video
I looked at the buffers at the bottom of the set - they are not connectors - they are bonded onto the board. Not worth removing display screen to check for bad caps or burn areas. I then made a executive decision and removed left side tabs (they removed very easily with pulling) and powered up set - perfect picture. Another tv saved from the dumpster...Leave a comment:

Re: vizio E60-E3 backlights, sound, no video
from reading all the posts on this issue - my right side of screen is good picture with left cable removed from TCON board from front of tv - all posts say to remove left side tabs from side of tv will restore the picture.

Re: Is this screen cracked?
posting this without a model # and asking for help ? screen is definitely cracked. Odd - yes but tv is still use-able. depends what your using it for. Not fixableLeave a comment:

vizio E60-E3 backlights, sound, no video
Have a free Vizio E60-E3 pickup - sound and backlights work. set turns on and stays on for a period then cycles off and back on. NO VIDEO. If I remove left side (from front of TV) of TCON cable - set has pic on right side (from front of TV) with white screen on left side. With right side TCON cable disconnected - no pic on either side.
Does this mean remove right side (from front of TV) tabs ?
Like a second opinion before possibly destroying set.... -
