Question about Mitsubishi WD-52725 52". Rear Projection HDTV

1 Answer

Random, intermittant blue lines

We are getting random horizontal blue lines in the picture, mostly in 1080i, and when the picture we are watching is dark, like a night scene. This has just started. We've had the TV since 2005. Any thoughts?

    We're not getting any red blinky lights. When we hold down the Device and Menu buttons, nothing happens as far as error code flashing.

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.

For example, 3 flashes, then 7 flashes = 37.

Here are the error codes, and the corresponding problem:

12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected

Mitsubishi rearTV has intermittent wavy lines running throughout

Do you have anything to test it in 1080i? Does it do it on all connections or just one? I had a similar problem with my TV that turned out to be a bad input board. Mine would only display 1080i through the Component connections. All others would show pink and green wavy lines. It cost me around 500 to fix it. Unplug the TV. Remove the back cover for the TV. Using a NON-metal object, or gloves, wiggle the input board (that has all the video connections on it) slowly back and forth and see if the problem comes and goes. You will have to have someone watching for you. If something is loose on that board, the problem should show itself. Narrowing down the problem will probably save you money on repair bills.

Horizontal blue line

The intermittent horizontal line is cause by a loose solder connection in the vertical amplifier IC.
The IC is mounted on a heatsink nearby or around the flyback transformer.
The way to fix this failure is to add fresh solder where you see some brown spots on the circuitry that were cause by components getting hot.
Good Luck.

Sony triniton 28" crt tv i have got sound but no picture

Any set can be repaired it is the question of the cost and the availability of the parts.

The fuzzy lines with static noise is probably from an arcing in the high voltage multiplier or in the flyback windinngs. I am very sure that the flyback assembly with the high voltage multiplier, and most likely the horizontal output transistor will have to be changed just to start. It is also possible that there may be some failure in the power supply as well.

The set would have to be serviced by an experienced TV tech. As for the cost, it will be a bit expensive.
