Question about Mitsubishi WS-73909 73" Rear Projection Television

2 Answers

MITSUBISHI WS-73909 will not turn on 1. I have a Mitsubishi Big screen TV model no WS-73909. Few days a go the city power went out when the TV was off. The TV had a surge protector. Then the TV will not go on and a small green light labeled ?timer? was blinking continually. 2. After about 3 days the light went off and the TV will go on. I turned it on and off and it worked fine. Then I disconnected it from the electricity to install a better surge protector between the TV and the wall. Now the TV will not turn on again and it has the same symptoms as described in item number 1 above. Did any one run into this before and knows the remedy?

It is normal for the green light to flash for 70 sesonds at first plugin the set will not turn on while it is taking place try it again after the light stops blinking.

now if your still having problems I need the error code
to get the error code Hold down input (device) and menue at the same time for 5 sec.

the led will start blinking an error code to you.
if it is broken we need the code.
thanks.

SOURCE: MITSUBISHI WS-73909 will not turn on

You can fix it yourself!!!

You need to replace the capacitors on your DM Power Board. It is easy.

It is easily fixable for about $10 worth of capacitors

Or a whole kit with all tools needed for $36

http://servicemanuals.vstore.ca/product_info.php/pName/v21v19-mitsubishi-dm-repair-kit/cName/repair-kits

That is an extremely common problem with Mitsubishi tvs old and new. It can be fixed easily and cheaply for those willing to use their hands.

Refer to this guide to replace the capacitors on your DM Power Circuit Board part # 935C9860. You could also have someone else do it for you for $100

Guide for a $10 DIY repair in capacitors : http://hdtvoice.com/voice/showthread.php?t=32186

Paid Rebuild Service: http://shop.ebay.com/?_from=R40&_trksid=m570&_nkw=PWB-PM-ASSY+REBUILD+SERVICE

That fixes the problem most of the time.

After replacing capacitors is you still get green light try replacing the EEprom. EEprom board also known as the E2P board is part number 935C978001

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

I have a mitsubishi 73' tv..we ordered a bulb but that wasn't the problem..,we have power and sound..the code light blinks really 6 times and yellow 1..can't find a code to match that,


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
http://homenol.blogspot.com/
http://electronicshelponline.blogspot.com/
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board...
