Common Easy How To Fix Most LCD & Plasma TV repair Review

[MegaGadgetinspector]

Hi do you know what might be causing my lcd tv to flick through menu options and volume and various actions as if i have pressed remote control, but it does it on its own? thanks

@MegaGadgetinspector - what brand or model # is your tv? try to reset it to facory settings or hard reset tv by unplugging powercord for 2 minutes

I have a Toshiba 50HP16 and it does not turn on but only the red button . I have open the back cover and I don't see any evidence of bad capacitors or burnt components .Please Help

[Tampatec]

@dragoneti67 - caps can still be bad even though they aren't bulged, 1st try a cap kit digi-key might have them check for fuses too.

[dragoneti67]

@Tampatec The caps in this TV look a bit different from other caps they look like alluminum cans .Is there anyway to test them without removing ? They are a lot and in many different sizes . The fuses you talk about are the ones in the power supply ?

[Tampatec]

@dragoneti67 -yes fuse in powersupply

[dragoneti67]

Is it safe to touch those capacitors without unloading them previously ? I've heard they store big amounts of energy

[Tampatec]

@dragoneti67 - yes some bigger caps hold a charge

[1961vampire]

@dragoneti67 Be carefull with these big capacitors, they can hold more than 400 V, and it can be dangerous. The best way to descharged it it´s easy. Use an isolated screwdriver and shortcircuit the two terminals, and you be certain that those capacitors were discharged. My english is bad, sorry.

[dragoneti67]

@1961vampire Thanks for the advice . which would be the safest way to discharge them ? removing the whole circuit board first and then bridging the two terminals together ? Also.My Plasma TV does not show any bulging caps.and it has many different sizes of caps . Is there any way to diagnose each one of the modules individually and replace the faulty caps ?

[Tampatec]

@dragoneti67 - buy the cap kit for your tv model# but it could be something else like inverter or t-con board. i discharge the caps with my body (just kidding) just use a metal screw driver but MAKE SURE TV IS OFF & UNPLUGGED, you may see a spark but thats expected when you short the 2 cap legs together.

[1961vampire]

@dragoneti67 First unplugg your tv. Second disconect all the conectors. Third with an isolated screwdriver you shortcircuit the terminals of that big capacitor. Then check the fuses on the power supply with an ohmimetter or with a multimeter in scale of ohms. You said you don´t see any bulging capacitors, but it don´t means nothing. If you have a capacimeter you can check one by one, out of the circuit. In power supply you a large conector. (Continue)

[1961vampire]

@dragoneti67 ... If you don´t have a capacimeter you can do another thing. In power supply you see a large conector. Near that conector you may have 5 or 6 capacitors and you can replace them all. Here, in Portugal, I spend 12 euros with 5 or 6 capacitors. In United States, I don´t know, but maybe you spend 10 dollars. It´s a cheap repair. I hope you understand my bad english, and I hope to be helpfull.

[1961vampire]

@dragoneti67 Attention: the capacitances must be the same. You can go up the voltage but never go down. Electrolitic capacitors are polarized, so there is only one way to conect them to the board. They have a positive and a negative terminals. The larger terminal is the positive and the shorter is the negative. The negative terminal is identified on the body of the capacitor too. On the board the terminals are clearly identified.

@1961vampire - great comment thx for sharing,

[detroitloveshair]

You guys are good and funny!

nice educational vid.

[CubansGoingCraZZZy]

thx

[orangestoneface]

maybe better just solder a longer wire to make easyer to replace them later , even put a clip on the end to grab a new cap wire. insead of soldering every time.

panasonic,sanyo.

For what it`s worth I got a new Monitor because they are so cheap now. I did not bother changing the capacitors again after they lasted only a year.

I had a Benq Monitor and will never buy that brand again, I got LG now so we will see how long this one lasts.

[omegafile]

Ya.. I fixed mine and it lasted a year and the capacitors blew again. Ya and i used the quality capacitors too.

[Tampatec]

@omegafile i hope it lasts but at least we know what to do if the tv doesn't turn on, thx for the info.

[SylentCommando]

capxon are garbage caps i have replaced some many lcds with thise caps.

[Tampatec]

@SylentCommando what caps do you use?
