    That would point to a solder joint issue.

        On Y-Sustain board taking out the fuse leaves the tv defective with the same symptoms.

        So I'm guessing something isn't right with the Y-Sustain board. I re-soldered the IPM chip.

        Still no go there. Guessing there isn't something right with Y-Sustain board.

            Or a IPM for this board?

            or if I take it out am I sure to find the IPM for it?

              The Y-sustains are available on most sites, just look under every cheap brand of TV you will likely find it.

                I found some on ebay but the prize for what the tv is worth is ridiculous.

                Maybe should just replace ipm

                  The problem is the model of the panel (42V6 or 42V7) is old, and parts are hard to get. A temporary fix may be to reduce Vs by about 5 volts and see if flickering stops, but it would be temporary at best.

                    yeah then theres the loss of color isn't there.

                    I'm afraid this one won't be saved as its not worth it in the long run.

                    should I just sell the power supply off and garbage the rest.

                    Thanks for your help Tom its been good. I'm only learning and understanding.

                    Fixing plasma tv's is allot harder than other types.

                      How much do you have in it? I would scrap it and sell the bits.

                        by Zippo978
                        Good morning everyone

                        I have this Telefunken te43550b40q2k TV that has intermittent backlighting, sometimes it turns on and then does not turn back on.

                        I tested the LED bars and all three work, not even one burned LED, then I tried to put only two bars short-circuiting the end of the connection cable and it does not give any problem the LEDs stay on without problems, I also tried short-circuiting the central connector and the initial one, always no problem, but as soon as I put the third bar, no matter the position the problems start again.

                        Thanks in advance...

                        Intermittent display on Sherwood Newcastle R-965 Receiver
                        by BigPete
                        Hi all,

                        I'm working on a Sherwood R-965 at the moment. It came in with relays clicking constantly and also going into protect mode.
                        I've re-soldered a lot of dry joints and replaced quite a few capacitors and now it works, but I still have one problem I haven't solved and would like some opinions.
                        The vacuum display is quite intermittent. Sometimes it won't turn on, sometimes it will turn on but the characters, numbers and letters are frozen on, regardless of which buttons are pushed. And sometimes it works flawlessly. If the display doesn't turn on initially, restarting...

                        HP Envy 13-BA1565na with intermittent power button
                        by themosttogain
                        Hope someone can give me some suggestions on this because i'm at my wits end with it...

                        I have an Envy 13-BA1565na here with an Intel Core i7 i7-1165G7 CPU (board is a LA-J475P Rev 1.0) which has an intermittent power button issue. The power button is integrated into the keyboard, and I have ruled out the keyboard, BIOS and battery as being the issue.

                        Basically, on mains power, the power button works fairly well. The first time you come to it after leving it sitting (either on charge or not on charge), it might take 2 or 3 presses of the button, but then the laptop boots...

                        Bose Wave I AWRCC1 - intermittent to no sound output - loud popping & crackle sounds
                        by proxneo
                        Dear reader

                        I have been asked to check out a faulty Bose Wave system belonging to a relative. The faulty unit produces loud intermittent pops and crackles. Sometimes there is speaker audio output (FM/AM, CD etc.), most of the time there isn't. This behaviour degraded over time fairly quickly, to the current situation where no sound is put out at all. Gently messing and wiggling wires, connectors or heatsink has no effect in force-replicating the problem. I have little experience in audio repair when it comes to (main)board electronic component faults. Bose repair WAS about 140$ (most...
