You most definately have bad capacitors in the power supply. try and get it repaired as soon as possible, not an expensive repair that iv'e seen.

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

I will keep you posted when the guy will return.

Look at the venting grills to see if you can see any white lights inside, if there is no light, the backlight inverter board may have gone out or the main power supply for the inverter board is not working. If you do see the lights then the problem can be in the main controller board.

Tv has lost picture


beginning steps to take:

if have sound look to see if menu shows on screen.

also look to see if you are on right input.

Next I would look to see if the filaments in the 3 picture tubes are lit.

failing that someone would have to take voltage checks (someone who knows how to safely do that) to see what is happening.

The TV has sound, can see TV menu screen, but no picture. We had a storm and this happened afterwards...


Make sure your devices hooked up to it still work (or are turned on). If it has a menu and you can change the inputs, its probable that your T.V. is fine.

Mitsubishi 50" Projection TV (Model VS-50603) Has sound but no picture


MJBNATL:

I reluctantly scheduled a technician to come out next week and take a look at my set. I was going to pay, at minimum, $65 for the service visit. I was then blessed with the intutition to do a bit more research regarding the PIP box being stuck on my television and other input functions (Inputs 1,2, and DVD) being unavailable.

I stumbled across a post on the internet that mentioned that the VS50603 can reset certain error conditions by pressing and holding the Input and Menu buttons (simulatneously) on the front panel on the TV while it is off. At some point after initiating this internal reset the LED light should starting flashing at defined intervals. The number of flashes correlate to a particular error code. Please go to the Mitsubishi website and download the owners manual (VS50609 in my case, couldn't locate VS50603) to lookup what the various error codes mean.

It seemed to me that that the LED flashing did not start immediately after pressing the Input and Menu buttons. In fact, I awoke the next morning to find the TV off but the LED flashing 10 times, pausing briefly, then flashing 10 times again. The sequence of the flashes mean something. Here again, consult your owner's guide for specifics.

Long story short, after awaking to find the LED flashing, I then turned the TV on and voila-my big screen was back minus that pesky PIP box prominently displayed.

I hope this helps someone like it helped me!! Truly a Blessing for sure.

If you lost the picture and even the menu does not show up on screen, then I will bet that your high voltage has shut down or the computer has stopped the picture because it has detected a fault in the vertical circuit. In either case this is something that cannot be reset with the buttons or remote and should be handled by a qualified tech.
