The only thing lit up on the TV is a "lamp" light,

Hi Genaro,

Blue led light lit solid and yellow led light flashes is an initial attempt of the set to re-light the lamp.Red led flashes and yellow led light solid means that the lamp won't light up that's why it only has sound without the picture.
Since you've replaced the lamp twice and still the symptoms persist, I suspected that the fault came from the ballast board and not on the lamp itself. If the ballast board gone to malfunction, there's no high voltage will produce to light up the lamp and will sensed by the processor and trigger the error code (Flashes/solid led light with color code).

To verify whether the ballast board is faulty or not, check if the lamp will lit by looking through the lamp door louvers at the rear of the cabinet upon turning on the set.
Please let me know what you will find to assist you further.

your color wheel is broken very common problem. Check that and chances are theres a large chunk of the wheel broken off.

Hello.
It looks like you ignored lamp replacement in your TV. It have to be replaced every 2.5 years of average use. It's like oil change in a car. Regular scheduled service.
You can read info about lamp replacement in your TV owner's manual, buy lamp on-line and replace it by yourself to save some money.

This is symptom of weak lamp in TV.
How old is this TV and did you replaced lamp recently?
If not, replace lamp in TV to fix this issue.
Lamp light does not lit solid if lamp is not broken or dead.
Lamp replacement procedure is easy and would written in user manual.
Thanks.

Your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. The sound is it starting up, shutting down, over and over.

You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

What it sound's like is that the lamp ballast is the problem. Buzzing sounds like when the power is first brought to the ballast it has to ramp up the voltage to get the lamp to light, then the voltage drops back down when the lamp is lit. Sounds like the lamp ballast isn't ramping up the voltage the way it should. May have to replace it. A good service shop would be able to do this for you.

My Sony lost its picture and had a flashing light. Unplugging for 36 hours solved the problem.

Good Day, bgblueeyess;
Your somebody is wrong; replace the LAMP.
Good Luck, big IRISH.
