I will need the model number of your Sony in order to help. Also does the led blink when you press power? If so let me know the number of blinks. Please respond to this same post

My tv is on but the standby button keeps flashing and I cannot do anything with the remote either I've unplugged it and left if for 30 mins


What make and model of TV is this? If its a LCD tv thats more then a few years old chances are its the very common problem of failing capacitors in the power supply. That will usually cause the issue your describing. I have rebuilt dozens of tv power supplies now, the term commonly referred to now is re-capping the power supply. The capacitors become leaky and the voltages go out of tolerance and the tv will no longer turn on. If you can find someone to take it apart and check the power supply board inside that would be your best bet, otherwise its time for a new tv otherwise. There is no simple fix other then repair unfortunately.

I have an LG 47LN522-UB LED TV that stopped working after three years and need help diagnosing a problem with it.


Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

My 32 in samsung tv is about 3 years old and has started turning off while i am watching a program then wil come on by itself after 5 or so minutes


This is a protection circuit that prevents the tv from coming on (to stop damage of the components) ....you need to check your voltages off the power supply and make sure they all read well (EX: 24v12v5v etc). Also look for popped capacitors that would make the values lower than need be for the tv to power on properly.


Once you repair the power supply then you may need to replace other components if needed (EX: backlight inverter)!



Please rate if this helps! :D


Replacing capacitors is ALWAYS the cheaper option, but you need to have experience it, or you'll create more damage than good!

I would recommend to repair immedately and stop trying to turn it on over and over...this will futher damage your tv and cost more to repair in the long-term.

After you repair the power supply's capacitors you may need to replace other components if needed


BUT always start at the root of the problem (power supply) and work your way to other components

While in operation the TV just shut off and can not turn it back on, not even manually. Could it need a bulb replacement? TV is only 3 yrs old. We know that it has nothing to do with the cable. If it is in...


There is no bulb in plasma tv's. LCD's have a backlight and projection tv's have bulbs.

Unfortunetly it sounds like your power supply has failed on you. It is repairable. At 3 years old I wouldn;t think you have any warrenty left (perhaps extended store type) so you want to get a repair estimate before spending any money. You may find it cheaper to get a new tv. Or not that much more. You should be able to get a estimate from Sanyo repair depots or tv repair shops or ask the local stores about repairs and they may tell you who to talk to. The repair cost can be reasonable but can get expensive if they find a lot of repairs are needed. The parts are cheap but the labor isn't (and shipping etc) so make sure you weigh out repair verse replacement to avoid a bit of a shock.

Blinking power button


Blinking power light is usually due to bad capacitors on the power supply. See the tip for RCA atc336 under my profile that can apply to your set as well.

that would be the inverter board, supplies power to the bulb, you would need to replace this part, but don't touch the board without wearing rubber gloves, as it can store a lot of voltage when they fail . when you get the board out discharge the capacitors to make it safe. cross the live and negative on the capacitors.
