Re: Bush lcd40fhda8
Is the main board you got identical (as in from the same TV/correct display type). This problem is common if the board is for a different display. In some sets you can change display type in the service menu, but if it's a recent Vestel chassis you would need to change the firmware, I've had no luck getting firmware from Vestel (other than for Comet OEM products)Comment

Re: Bush lcd40fhda8
Ok so you need to test and list the 13 gl voltages that are in a line with 1 below - the description for them is above,
There is also another 4 points I cant see the description for and i that is VGH
there should also be a VGL if you can spot it.Attached FilesPlease upload pictures using attachment function when ask for help on the repair

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

i have a 2020 macbook pro 13" A2251 with 820-09149 logic board so i found an issue with chip labeled U6903 according to schem. boardview using flexBV software, so i removed it from the board and the issue im having is that the chip says "07A08FI ELC180" on top of it but when searching for a replacement chip, i can find tons of identical looking chips that also have "ELC180" printed on them but the first set of digits is never the same so im trying to find out if i need this exact chip with these same numbers as mine and if not which ones are compatible as a replacement?... -
Hello my friends!
I have a question that I think you can answer and help me with!
I have a faulty main board from an led TV. And I found the same part number board and design but is from a 43" TV and I want to use it on a 65". On its stickers , all are the same except the wattage for the LEDs backlight, both state different watts and LED Voltages!
So I presume that the backlight inverter section from the replacement board has lower wattage then the original one, am I right?
My concern is that the board won't draw enough voltage to the bac... -
Hi,
I try to repair this fly-back type PSU, I diagnosed (identifiable) dead N-MOS and fuse, but there are 3 smd resistors on the bottom that burned and became unreadable.
The support in charge of the brand in France managed to get me the schematics from Ecler, but it didn't include the PSU board. After a while they finally told me that the unit was too old so they don't have the PSU board schems.
I can find replacement PSU board online, but only for the Nuo 3 or 4 or 5, and it seems they ar compatible with each other, as I often find boards compatible with these... -
Hi There,
This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.
After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.
More Details
TV Model - LG OLED77G1PUA
Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...
