If theres absolutely no power and no lights on, it sounds like the fuse inside the t.v.. It is pretty easy to change. You have to take out the screws on the back of the t.v. and take the back cover off. Look for a 3/4" glass tube fuse and see if the tiny wire in it is broken. Pop it out and bring it to radio shack and get a new one. Put that one in and try it, Make sure the t.v. has been unplugged for at least 2 hours before opening it so the capacitors have time to drain. They will hold power and could shock you if your not careful. Also, dont use anything metal to take the fuse out.

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.

Hi,

The Standby/Power light of the TV blinks when there is any internal malfunction in the TV. The self-diagnostic function of the TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue.

Few examples are given below; some of the issues may be resolved without the need for service.
1 blink / 2 blinks / 5 blinks: - This indicates that there may be a power-related problem with your set.
3 blinks: - This indicates that there may be a power-related problem with your set. The set will need to be serviced to allow a technician to determine the specific issue that needs to be repaired. If the power light flashes three times in sequence in a Lamp TV, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
4 blinks: - This indicates that there may be a back light or lamp power problem.
6 blinks: - This indicates that there is some kind of audio problem with your set.
7 blinks: - This indicates that there is a temperature problem with your set. Please check to make sure that the air vents on the sides and back of the set are not blocked or clogged and there is adequate ventilation around the television. We recommend that you check and clean the vents periodically to make sure the set receives adequate air flow. If the problem continues, the set will need to be serviced.
8 blinks: - This indicates that there may be a video-related problem with your set. If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.

If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.

If the issue continues to occur, service may be required.


Thanks for using Fixya.

My Sony wega tv won't turn on goes into standby red light blinks 10 times then shuts off?


Look at the owner manual as the 10 blinks is a error code or Google the model number to locate that information--Sony error codes are general and often misleading.

I would if looking at the set inspect the lamp first.

My sansui hdlcd1909 19 in. lcd tv won't turn on. the standby red light blinks once, what can i do to turn it on?


sounds like bad capacitors on the power board. Very common problem. I would look at the caps if any appear even slightly rounded on top they are bad. They should be perfectly flat on top any puffing up means replace that cap.

12 blinks of standby light indicates 'Scanrate error'. You must have thorough knowledge in electronics to proceed. Actually, this is not a user repairable fault. it is very skilled work.

TV won't turn on


Before going OFF, the standby LED might blink. These blinks are fault indication. The number of blink should be counted. Count the number of blinks at one time, before the TV goes OFF. [eg: 4 blinks Power SOS P Board; 6 blinks Driver SOS 1 SU / SD / SC Boards
(SC energy recovery circuit)] and so on. you can get more details from this site named 'Electro-help'. You can reach it by searching the keyword "electronicshelponline" by internet.

The below doesn't work with all Panasonic equipment but if this fails then the only fix is a replacement Laser which isn't cost effective.

U61 Fault
Corrupted or Faulty DVD in Machine.
  1. Put Machine into Standby
  2. If won't go into Standby hold 'Power' for 5-10 seconds
  3. In Standby hold 'Stop' & 'CH UP' together for 5-10 seconds until tray opens
If this fails then re-initialise the Machine as follows
  1. Put Machine into Standby as above
  2. In Standby hold 'Stop', 'CH UP' & 'Open/Close' together for 5-10 seconds.
  3. Hello displayed followed by TM AV1
  4. Put Machine into Standby

Turn it on yesterday and i can hear a clicking noise for approx 5 secs then the standby light comes on and no picture. any advice, or reccomened repair


1st POSSIBILITY.....usually after 4 or 5 yrs EHT ( transformer that supplies voltage to tube ) becomes weak - then TV won't get ON.. means no picture no sound ( in some TVs ''garrrr'' like sound comes - that sound is from EHT.... but it is rare....some times ''click click'' sound comes...it is from relay switch ) ..... but LED blinks - in some TVs along with EHT 1 or 2 components like resistor, transistors, etc will also gets deffective ................ 2nd POSSIBILITY - main capacitor (very big in size) is blowing off...................... - so solution is TV circuit board has to be checked to find whether only EHT is deffective or other components are also deffective - price of EHT will be between Rs.250 (US$ 5) to Rs.600 ( US$ 12) & price of capacitor will be between Rs.50 ( US$ 1) to Rs.150 ( US$ 3) ..........iam from bangalore.....i have no idea about component's price & service charge in your area.....this problem cannot be solved by user unless user is a technical person having idea about components (resistors, transistors,diodes,...etc..), having multimeter , soldering iron & other tools...so my suggestion call TV service engineer or contact panasonic service centre
