Tv turn on no pic or sound


Try unplugging it for about half an hour, plug back in, if it still does not work, you will have to open it up and do some troubleshooting.
Please see my basic troubleshooting guide here:

Been gone 3 months, came home turned on tv and had a pic for 5 min,it went out, sound stays on and can change channels but no pic. Turned on again after leaving set off for an hour, again, sound but no...


Had the same issue sound but no picture, try wiggling the connections to the back of the tv, if that does not work try using a different hook-up, I ended going from the component jacks to the DVI hook-up and this took care of the problem, hope this helps!!

Tv turns on w/pic then pic dissapears light blinks 4 times


I have the same issue, we've had to change our bulb three times in less than two years. now we have 61" expensive paper weight. Our current bulb is less than 6 months old. The TV is only 2 years old and like i said this is our third bulb.

the blue light blinks 4 times. you get sound. then a few minutes the the picture returns... then it goes out, and the cycle goes on.

A solution to this would be greatly appreciated.

Vcr hooked to tv and converter box. Will not record digital chann


The vcr has to be set to channel 3 or 4. The converter box has to set to the channel you want to record the show from and left on during the time that the vcr is recording or you will get no recordings.

Mitsubishi ws-55513 HELP!!!


Same thing happened to me.On the signal board there is 4 surface mount transistors. There is oneright by the input board (BA09), i would check the corresponding capsand diodes2_bing.gif close to it also. I would replace all of the 4 transistors.If this SMT starts to go you will see wavy lines in your picture thanit will go away in 3 min or so and get worse over time until no pictureis seen. When it totally fails you will have no inputs what soever butyou will have an OSD screen and when you choose DTV you will get ascrolling picture.
