Question about Mitsubishi LT-52151 52 in. LCD HDTV

Open Question

The picture will not come on. When powered up the screen goes blue, the green light steadily blinks, and after 20-30 seconds the unit powers down. This problem just started a few days ago, and it would usually power on on the 2-3 attempt.

SOURCE: Mitsubishi WS-65313 - Will not turn on

The most common failure are the two convergence integrated circuits part # 267P173010. The two pico fuses may be open as well, which come from the power supply and provide +24 volts and -24 volts.

SOURCE: power was off

You need to replace 4 capacitors on the DM board. It is located inside a metal box on the left side of the set, looking from the rear. The original parts are 1000uf 16v. You will need to install 1000uf 25v or 35v. They are located at the top of the board and are green colored.

SOURCE: powers on for only a few seconds

if the power light blinks and the status light is off, check the lamp door. if the power light blinks and the status light is steady red or blinking green, you have a power supply/ballast issue. you may have to send it in for repair. try www.avsolutionsny.com.

II get sound for about 15 sec. but no picture and then shuts off


kp57ws50_57_in_rear_projection_hd_228277.jpg Problem with Sony KP-57WS520 57 in. Rear Projection

This model is really prone to one problem in particular--screen even briefly comes up bright red, green or blue and set shuts down.

15 seconds from turn on front power light should blink as set checks several things internally---if something wrong it does not let picture show.

Usually after shut down or failure power light will blink a sequence of blinks but not always depending on problem.

Did you see the screen at all go red, green, or blue before?

the more you tell me the better I can help

Did you check the service manual troubleshooting guide yet. You can try disconnecting the power to the inverter board and see if it will stay on and have sound.

  • Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen A2 slightly.

My Sony KP-46WT500 screen shows the tv image in blue only for a few seconds, then it goes completely blank (as if it were off). Do I need to replace the bulbs?


It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen.
Do you see standby red light blinking when TV shuts off after showing blue image for a while?
If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution.
Thanks.
