We had a problem with the tv shutting off by itself...had a repair done that took care of that problem...soon after the tv screen would not hold it's horizontal picture, and would start flipping as soon as it was turned on until it "warmed up" and then you can get a normal picture....but then if you watch to long it will start getting shaky at the top of the picture.. Is this something that can be repaired...obviously there is no warranty....is it worth fixing??
Re: mitsubushi rear projection 50 inch bought in 2001
I would say the last repair knocked a solder joint loose in the vertical circuit. This is a common problem when moving rear projection circuits boards or the whole tv. I have had customers move their TV from one room to another for what ever reason and when they moved it back it wouldn't work right. These sets get real hot and destroys the solder joints. Is it worth fixing??? Only you and your wallet can decide that and of course the local service man and what he charges.

My Samsung big screen showed the same symptoms. It ended up being two $5 resisters that burned out a very short time after purchase. My extended warranty took care of it but it took several service calls and the end solution was to replace the entire light engine.
Most of the time heat is the cause for shut down. Check the vents which allow air to circulate thru the set, also be sure the fan is working.
The first thing a repair man will do is replace the bulb. If you can do it yourself you can save some $$.
My advice is to find a good TV guy. One who's been around for a while. Sorry couldn't be more help. Good Luck!
The television is shutting itself off to protect itself. The blinking light is a code pattern. The specific code determines whether or not you need an LCD Controller Unit, Main Board, power supply or something else. You would need the service manual. There are parts distributors you can get it from and the parts as well. If soldering and tv repair is not something you are entirely familiar you may want to seek a tv repair person. The manufacturer's support may walk you through the service menus to complete a factory reset depending upon the symptoms.
That is sort of a generic defect. Even having the model number won't help there. All modern televisions have what is known as "protection circuitry" which will shut your set off if it senses a defect. More than likely the trouble lies in either the power supply itself or in the Horizontal output section. I suspect you will need a shop repair to correct that. There isn't much that can be done without opening it up and troubleshooting it.
I had the exact same problem. Googled and fond someone had gotten the tv to stay on by hitting "enter" on the remote as soon as they saw "AKAI" logo onscreen. That didn't work for me, but it got me holding other buttons down on the remote, all tried no go. So I then decided to tinker with buttons on the tv itself and VOILA! If I hold down the MENU button on the tv, the damn thing works perfectly! Every function still works from the remote too. So I taped the MENU button ON THE TV down, and all is well. After having the tv sit for 6 months, tripping over it during a move... now I have it back and no repair bill. Hope it works for you guys.
Water can be very damaging to TV circuits when not dried up completely as soon as possible. Water causes corrosive damage to the printed circuits as well as the small components. It needs to be dried quickly, as with a hair dryer. Your set probably has suffered component or pc damage, and will probably have to be repaired by a professional. The cost of your repairs could approach replacement cost of your TV.
The problem is dry joints on the vertical output ic for sure(commen fault with sony),ime in the uk and 99% of the time i get a call about sony tv its allways switches itself off, caused by dry joints.
