    Technisson Lc-32IEF4

    I got a Technisson Lc-32IEF4 s/n: 72s00602693 LCD TV from a friend, he told me its not working, not even powering on. He told me that he used it for 2 months and suddelny it just not powering on.

    After the disassembly I've found something that I dont understand, take a look at the pictures. Do you have any idea what is that wire soldered on the board?

    By the way, I'm sure somebody was already disassembled this TV because there were different screws in the case, some of the screws are missing too and some of the cable tapes are loosed or removed.

      Well someone made a mess in there, If it was me I would unsolder the extra wire from that connector, then reflow that cap next to the end of that wire, looks like cold joints on both legs. Then start checking your voltages.

          Well, thank you for your reply, much appreciated!

          I was just wondering, how could this TV work with that wire + careless soldering. Since I've never seen anything like this + I was unable to find any logic behind it I wasn't brave enogh to touch it. (Maybe someone was a genius or just a fool, can't decide ).

          On the other hand, this is the first TV ever ever opened. However it is similar to computer displays, still a bit different. Could you tell me how can I check voltages? I have a really basic multimeter, not sure if I can do it with it. If it is possible, could syou tell me how and what should i measure? I'm attaching a pic of my multim. I'm quite beginner, till now I was only encountered with bad rectifiers, bad joints, resistors and caps only. Your help would be greatly appreciated!

          It would be lifesaving if I could repair this TV.

              Well, great news: I did it, its working now! Unsoldered the wire, checked and strengthened the soldering on the 14 pin connector and the 4 caps. I think I did a great job!

              Thank you again for the advice!

                  Bad news... TV is bad again. When im connecting the power cable the led is red and turns to orange, no blinking. Cannot power on with remote controller or power button. Any idea?

                  Found this forum since its similar to viewpia, but it cant help since there are no C905 or 908 caps

                      I would check the startup cap on the power board as well as esr on all the output caps on the power board. If someone bodged up the repair that badly they may have tried to replace the caps on the power supply as well.

                          Sony LED 65X9005A shuts down after few seconds - looking for help
                          by tec3000
                          Hi community! Germany calling I am wondering if you guys can help me out. I have an issue with my Sony LED TV. I've been told this is a good place to ask. Thanks for anyone who will reply and offer advice. Appreciated!

                          I have a KD-65X9005A Sony 4k LED TV. For a few weeks I've got this problem where I turn on the TV and within a few seconds the TV starts getting darker until it shuts itself off and I get the 4 blinking error code. HOWEVER there is one exception: Whenever I switch to the i-Manual, a full screen on-screen instruction manual, the TV never turns off. I tested for hours!...

                          New wire for my RDE3340 Whirlpool electric range
                          by wnlewis
                          OK. I got the rocker switch figured out thanks to the good advice on this forum.

                          Now I need to figure out the correct wire to go to the switch from the broiler element and from the oven element.

                          This is a Whirlpool RDE3340 electric range.

                          The common wire on the switch appears to have a high temperature insulating material. I am guessing that both the wire to the broiler and the wire to the oven elements also need relatively high temperature insulation. What do I need to look for? The broiler is rated at about 2400 watts.

                          Where may I find parts...

                          by emeskay
                          We have an Lenovo Yoga 710 15ISK that we use as a secondary laptop. To cut a long story short, around May 2023, while traveling, I connected the laptop into an electrical outlet that was already switched on. Something made a "pfft" sound and the laptop refused to turn on after that. After getting back home, I gave the the laptop for repair to an informal repair person. He replaced the adapter and an internal motherboard part, but after he returned it I noticed that the LCD did not look normal. Essentially, every alternate horizontal line on the screen had gone missing. The laptop was...

                          Vintage fan repair, copper wire question
                          by technicalspecialist
                          I currently have a customer's vintage fan on the work bench to repair.
                          It uses an induction motor with 4 poles. One of the poles is open.
                          I couldn't find the break so i cut off the original wire.
                          I have measured the other poles and the resistance is about 28 ohms per pole and I measured the diameter of the wire with my digital calipers and it is 0.35mm in diameter.

                          I need to work out how much 0.35mm diameter enamelled copper wire i need to order for it to be 28 ohms. I have used this calculator and it says i need 160.35 metres.

                          The enamelled copper...

                          Heater element wire type instead of a fuse when troubleshooting a short circuit DIY
                          by sam_sam_sam
                          I was Ollie today which is a close out / surplus outlet store I do not go in there to often because you find things that you should not be tempted by but that is a another story

                          I saw a small space heater that used a wire type of heater element which I been looking for a while but not really hard mind you but when I saw this I grabbed it I going to go back tomorrow and buy the last one that is like the one I bought today because I need the heater element and the ceramic insulators and more of heat element wire because this one has two different wattage settings one 1300 watts ( tap...
