    Are the lenses placed centrally back in place. Perhaps the replacement leds are brighter?
    Willing to help but I'm no expert.

        Halos usually caused by lens not being centered or sitting too high. Did you scrape down the old black glue nubs and make sure the lens is correct orientation

          Yes I removed the old glue first then attached the led but still the same then noticed how high the good working lense was so worked out how high they are glued and used some paper to wedge and now working and in test mode no halos at the moment

            Philips 58PUS7805/12 showed no picture; after T-Con replacement, shows halo
            by Rauni
            Hello, this is my first post on this forum, and my first attempted to repair a TV.

            My Philips 58PUS7805/12 stopped working recently. It is not that old, about 5 years. We were on a trip for a few days and when we came back, it had stopped working out of a blue (Perhaps our house was hit by a lightning strike? Don't know.)

            Read from a guide that I should test if the screen shows picture with one of the T-Con cables disconnected. Did that, it showed perfect picture (first on left, later on right side).

            Read also that we should test what happens if we...

            Looking to buy a microscope
            by Dannyx
            Good day and a belated happy New Year folks !
            Wow....feels like forever since I've had a chat with all the wonderful folks we got here - guess you could say I grew up and can look after myself now
            In all seriousness, I'm in need of some assistance choosing a microscope. I decided it's time I finally got one and I might as well put some of the money I earned caroling this year to good use

            The reason I'm turning to our community for advice is because I'd like to hear some thoughts from people who actually own a microscope already or at least worked with them hands-on,...

            Soooo, I found someone giving away their 70" Vizio TV because it wouldn't turn on. Hoping it would be just some bad caps, I snapped it up. No dice. No bulging caps. TV would start consuming about 7W immediately after plugging it in, but no response from the remote or power button. Thermal showed the main chip on the mobo getting warm and nothing else. Power supply appeared to deliver stable 12V to the mainboard.

            I ordered a replacement mobo(actually both mobo and PSU just to be sure) and popped it in. Picture! Sound! Endorphins! Then I noticed three long dark strips. Hmmm, had...

            How to trick notebook into thinking internal panel is connected?
            by joshAU
            Hi all.
            I have an asus F505DV that has a smashed screen, broken hinges, bezel and top cover.
            The customer cannot afford to repair it, so they wanted me to remove the top of the unit and will just use the base as a desktop and plug into a monitor via HDMI.

            However, for some reason, with this model, it REFUSES to display on the external monitor unless there is also an internal LCD.
            If there is a internal screen, then the external displays fine.

            This is running the latest BIOS.

            I have set the display properties in windows 10 using...

            Halo 5 inch and 6 inch White Integrated LED Recessed Downlight, destroyed by 180v power surger (Newfoundland Power Company).
            by Bubbsy 2002
            Hi all, I am on a 100% diagnostic spree and need some more assistance.
            I have looked at the board of this poor light and it appears I have an fuse/resistor combo.

            I have isolated what I believe are RV1 (destroyed by the surge) and you can see RV2, so I am assuming they are same or similar.
            Can you tell me what the name of the component, amperage/resistance, so I can order from DigiKey?

            And now I noticed the light went up $10 Canadian, to $46.

            Any help in this regard would be greatly appreciated....
