LOT fault. Check the horizontal output circuit. Check horizontal output transistor. If this transistor is faulty, this kind of buzz sound can occur.

Testimonial: "Thanks, Gopa, but I am not a tech-type and the only person in this tiny town says you can't get parts for a TV this old anymore. Maybe he just doesn't want to deal with it. Thanks for your input, I wish I could fix it myself."

I'ts possible that by accident someone activated the parental lockout. Your best bet is to locate your instruction manual and find the default code. Also problems(usually with software) can cause the the tv to do unusual things. Leave the set unplugged for at least 24 hours, the see if there is a response with the buttons on the tv. You may be able to reset the set to factory defaults. Scrivitron

SOURCE: power surge-no picture or sound, just red blinking power light

Any malfunction associated with a blinking redlight usually indicates a circuit problem or defective component. Unfortunately, the days of taking off the back cover of your TV and replacing a defective tube or fuse are long gone. Proper servicing will require troubleshooting procedures that can only be performed by a qualified electronic repair facility or professional television repair person. Ask for an estimate and a realistic appraisal of whether the set can be adequately fixed. Depending on the age and condition of your TV it may not be cost effective to repair.

I unplugged the TV and held the buttons down and it continued to flash. I continued to hold down the two buttons and replugged it in again and it worked. TV back up and working.

Unplugged it. After looking for a new tv online I decided to try getting it to work. So, plugged it back in and held down the power button, a red light came on, held down the power button again and an orange light came on, held down power button again and green light came on and tv powered on. This was simply a case of trial and success!

unplug, hold power button, plug in. If that doesn't work, unplug all the HDMI cables, unplug the power, hold power button, plug back in.

Mitsubishi WS65611 no remote function & panel buttons not working


This TV is known for the buttons going bad. You can remove the speaker grille to gain access to the wires for the panel. You may have to pull off the font access panel to get to the connector. There will be two of them, one for the input, other for the control panel buttons. If the buttons are bad, unhooking them will make the TV work fine with remote. I believe the connector is labeled ZR and is not the one with the thicker black wires (shieled video wires). Unhooking is my fix for this problem as replacing the buttons seems to be only a temporary fix.

Printer doesnot Power On (no power surges either)


In case of Power Failures / Surges.....we should first check if the h/w of the printer has gone Bad... Try the following in the specified order... 1. Unplug the power cable at the back of the printer and replug it and then press the "ON" button on the printer to check if it works else... 2. Unplug the power cable from the surge protector (if you are using one) and replug it and then press "ON" button else just try unplugging from the wall jack and replug the cable (if you are not using a surge). 3. Else , Try a different wall jack 4. You may even try taking the printer to a different room and then check if you get some power. Now if the printer powers up but the "startup cycle" continues...it needs a "semi full reset" to do that-> 5. unplug the power at the back of the printer and 6. press # and "6" at the same time on the front panel 7. while holding these two buttons , replug the power at the back and keep holding till you see "semi full reset" on the screen 8. Now release the buttons and let the reset complete...you may be prompted to enter the language again etc.... Even if this doesnot work...try a "full reset" 9. Which is done by pressing "#" and "9" simultaneously with the same procedure Else the firmware(program inside the printer) has gone bad and may need replacement I got this valuable information from the engineers of ***
