Re: 42'' projection tv timer led light blinks

I hope that this will help you. My wife and I had the same problem, but we had a warranty from Circuit City. The repair person must have know what the problem was. He put a new circuit board in the TV in less than five minutes. It took him longer to open the TV than to put in the new part. No cost to us, but if we had to pay if would have been in excess of $65.00

Re: 42'' projection tv timer led light blinks

Mine does the same freaking thing, and Akai Has zero customer support. The manual is utterly useless. I would be happy with 50 fewer features and a reliable TV. Why throw all that stuff in if it means more things can go wrong? I will never buy Akai. I am going to take it to a TV repair shop and see how ridiculous the cost is to fix it.

You will need technical experience to fix. First what do you remember happening to set before it went out? Did you have color problems, or alignment problems? There are many things that could be wrong. Open startup resistors, R600-612, IC 601, C667,607,608 etc .

Blinking green light under 'Timer' flashes there is no picture

If you have a green blinking LED that runs continuosly, its the widespread problem of failures of capacitors on several circuit boards in the TV. Currently Mits is having authorized service centers remove the chassis and send it them for rebuilding. Its an expensive and time consuming repair.

Turn on the TV and only Timer light is on , no sound & picture

after holding down the menu and device the led will blink a two digit error code such as 3 blinks pause then 4 blinks then repeat that sequence a couple of times. Need that blink code to help let you know whats going on. The 34 code means lamp abnormality which translates to the power Pwb capacitors have most likely failed.

Mitsubishi VS-50607

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source.
