If this is the case, the headphone socket to your TV should be checked. Contact any service technician.

Try changing the input device to something you are sure, works such as a DVD player. Check for any loose contacts of cable, RC jacks and Sockets. If none of these work, you may better involve a qualified service technician.

Recently I replaced eeproms in
Hi Max,
I've searching online for the service manual of this model no. but it is currently not available. I have a copy of the LA40R81BX chassis no. GBP40SEN series. that includes the factory data for the service menu and I believe it will work for your unit too. Email me at
[email protected], I will send you the copy.

Recently i replaced eeproms in lcd's la40r81bd
Out of curiosity why did you replace the eeproms?
In my opinion only good solution to the problem would be to get an image from a working eeprom and burn it in the replacement.
Manually setting up data sucks.

My samsung tv's backlight doesn't work can
yes; you can replace the back light of your lcd, when you remove the back cover of your lcd you should remember all the parts that you will try to remove specially the screw, then you will see a rectangular pcb in the other side it has a small transformer this pcb is the inverter of the backlight of your tv try to follow the wires that is connected to this inverter and you will see the back light of your lcd, try to check the tube both end if there is black color then it indicates that the cathode tube is already damage.

Hi
I 'm la40r81b model lcd
In most cases the standby light might blink with different rapidity to indicate a fault relevant to the processor. It is possible that most of these indicate that there are errors in the processing section . Since there is a possible short or leak in the circuit the output driver section can take in huge current to trip the SMPS or from advice from the micro processor. Remove the power plugs and make sure that high voltage sections are discharged of the potential stored in capacitors. Look for visible signs of leak or of busted capacitors. Look for bulged capacitors or damaged components- burnt or busted. Use a multimeter to check the continuity or shorting in components, if so detach from circuit and test . If the voltage builds up and the set power ON and then shuts up then the suspected section must be checked in detail.
The processor must have the +5 voltage to the function properly , the +B and secondary voltages also must be checked to infer the fault. Trace with caution and in running through the signal path , circuit trail.
