    Re: Burn in question

    Can you post a graph or list? The voltages should monotonically increase or decrease from VG1 thru VG## (whichever the limit is, 14, 18, 20, 22, etc.) I've not yet seen a TV with bad gamma voltages that wasn't fixed by new gamma IC. Perhaps you got a bad or recycled IC (removed from dud boards, etc. Common from China!)

        The first atempt it wasn't succesful. I'm not sure if the IC did not get damaged then.

            It was the AS15-F IC.
            Most likely, I didn't do a good job with the other chip.
            Unfortunately, I managed to rip up a pad.
            I have managed to replace successfully the IC and added a tiny wire from the IC's leg to the continuation of the ripped pad. Damn this job it was tiny.
            In the end, all went well and the TV it's working great now. Yeahh!
            Thank you for the help!

                HANNSG Hi221 -- 2 secs to black feat. CCFL flicker & "burn" marks on power board
                by ttmi100x
                Greetings everyone,


                I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...


                The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
                Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.

                Upon closer inspection...

                Denon AVR 1908, High pitch noise on Surround back Left channel after long overhaul
                by karatzdi
                Hello,

                I know some might say... just buy another one. Sell it as parts..!

                So had this AMP for quite some time. Recently I saw light smoke coming out of the AMP. Had my fire extinguisher close by. Just kidding. Turned immediately all devices off from mains.
                Let things cool a bit, and opened up the amp device. I clearly saw on the main board which hosts the 5X amp (5.1), 3 10 ohms 1W resistors had their leads looking black, while the rest of the remaining 2 x 10 ohms were brownish as being installed from factory.

                Spent some time downloading the Service...

                Vizio M60-C3 Left Edge problem
                by Pinky Deepak
                I have a M60-C3 where the left edge has started showing issues as seen in the picture attached. Along with this, I also noticed some darkening on the left half of the screen which went away after I left the TV unplugged. i initially thought it was the led backlight that was wearing out but looks like something to do w the TCONN board. I searched this forum but couldn't find anyone else seeing this issue. most of them were LH/RH completely gone. any insights or guidance is appreciated.

                Here's a video of both the issues: https://youtu.be/hMqc760nB3o

                Panasonic Tx-40cx400b top left half screen not displaying correct
                by armoured_smiler
                Hi,

                Trying to work out if this is TFT problem or TCon issue.
                The TV powers up but the top half of the screen, from the right it is OK, but as you look across to the left halfway across it starts get duller and duller until it is very dark on the lefthand side, currently I trying to clean the remote as it seems to have something film wise on the pads stopping it from registering buttons pressed.

                Also when changing the screen size of Windows PC display to say to a smaller pixel sizewindow, the original window displayin the top left stays/takes a few seconds to disappear?...

                HH Scott Model A510 Stereo Integrated Amplifier/ Graphic EQ - Blowing fuses in the LEFT speaker channel only. Any Help???
                by Sik_6ty_Sixx
                So like the title says, I have an old Stereo Receiver/Amplifier that I picked up from the goodwill, it's a HH Scott Model A510. When I first got it home it had zero output. Opened it up, notice the fuses are missing. Pop in 2 new fuses (AGC4A 250V) and try again, within 5 seconds the L channel fuse POP! I don't see any visible indications of damage or arc burns on the PCB, no popped resistors or diodes, no burnt traces or blown out caps. So I decide to just try another new fuse, POP. Swapped around my R and L speaker wires, and checked the integrity of all wires and connections. Everything looks...
