SOURCE: Not turning ON, fuse blows.

In most cases, it is either a shorted component in the power supply or a shorted horizontal output transistor. It will take experienced electronic troubleshooting to fix it. TVs have lethal voltages (both 110V and 25,000V kind) and improper repair can result in shock, injury, or the emission of X-rays by the TV! Be safe and either replace the set or have a shop work on it for you. I'm a tech with over 25 years of experience, by the way. I appreciate honest rating of this reply if you find it helpful.

Look Do this
Replace your STK's

My 74cm Telefunken colour tv dont work


Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

How do i check if telefunken mp514 remote is faulty


Hi,
Many things can go wrong with a remote control but one easy check is to look at the control LEDs using your digital camera or phone camera. Press any of the control buttons and you should see the control LED flash on the camera screen. Try this on a good working control so you know what to look for. If you dont see the LED flash clean the battery connectors first and then try new batteries. If you have got functioning LEDs but no remote operation check that there is nothing in the way of the TV sensor.

What is the code for a universal remote in order to tune telefunken mp514 tv


These are the universal remote codes for Telefunken Brand TVs: 0031 0000 0001
Try this method, if none of above codes work.
Code Search
If after trying "Direct Code Entry" your device does not respond, or if your brand is not listed, try doing a search of the code library for your code by following these steps.
  1. Manually turn on the device (TV, VCR, etc.) to be controlled.
  2. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
  3. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks once, then stays on.
  4. Press the CHANNEL UP button repeatedly (up to 300 times) until the device to be controlled changes channel. The red indicator blinks, then stays lit.
  5. Press and release MUTE to install the code. The indicator light goes off.
Most users will want to store VCR codes under the VCR button, Cable codes under CBL, etc. If you want to store a VCR code under CBL, etc., first follow the procedure for Direct Code Entry and press CBL in step 2 of Direct Code Entry, then enter ANY VCR code in step 3 of Direct Code Entry. Then follow the steps above for Code Search.
If you wish to get more details check this.

My Telefunken 42" Full HD


The problem might be on your power supply.

1. Check the power supply it is located on where the plug is connected on the main board.
2. Use a multimeter it must be on AC function, to check the AC supply
sometimes the problem is just on the plug
3. Then if there is an AC supply on your plug then check the power supply
4. Check for busted fuse (usually has no reading on multimeter on diode test)
replace same type of fuse.
5. If the fuse are good check for open resistor or shorted transistors.
always replace same rating of resistor and transistors (same on number and type)
IF the problem still exist just contact me.

Hope this may help you..

Hi , I have a Electronic pilot lighting system on my RUUD package unit. The pilot light flame keeps blowing out or is not working properly. I removed the panel to look and see what was wrong. I could not...


Sounds like you have checked most things. A pilot will go out if it is dirty, if the gas valve is not holding or if the senser is dirty or bad. Remove the pilot and clean out the small orifice inside. Check all electrical connections, clean the sensor, and make sure the gas valve holds 24 volts on the PV side.

Sony KV-32HS510, worked perfect, turned on the next day and all I gat is flashing red light.


Your tv does not need a reset,what happened something went bad inside the set and it needs to be replaced,if you are familiar with tv service you can start by checking the horizontal output transistor for a short,if he went bad it likely made the fuse or safety resistor open.If you are not too familiar with tv service be safe and call for assistance froma servicer.If you decide to go in looking for problems make sure the set is not plug in.Let Us know how it goes or if you need more information.
