The TV shut off automatically but the powerlight is blinking


Your power source seems to be the problem, replace the part (located inside the television) and the problem will be solved.

The color is distorted and the picture blinks. I've replaced the lamp twice before and i don't think this is a lamp problem.


Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

The screen on our 50H81 Toshiba is blank, there is no audio and the red light by the power switch is blinking at a rate of one blink per second.


The most likely cause is shorted convergence chips and possibly a few pico fuses.

Picture & sound go on & off every sec, red light blinks 5 times


helloFive 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 slightly.

Blinking powerlight on front when i try to turn on tv


This is more likely a power supply failure. Most causes of tv failure are due to bad capacitors on either a system board or the power supply. In this case, it sounds like the power supply. You can test the capacitors with a capacitor tester to determine faulty capacitor. You can also test other components like power supply current with voltmeter or mulit-tester.

No blue auto convergence when performed by menu buttons


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded over.

No picture, sound OK...setup menu shows up, able to get picture in PIP


You will need to check the inputs on the television. You more than likely have a bad video in signal. This can be a bad cable or a loose connection either at the input of your television or at the output from your receiver, (cable or satellite). First, try wiggling the cable and then try replacing it. This should fix the problem. If not, your signal may be routed through a stereo or other switching device?
