Your TV cannot reproduce 1080p resolution so go into the menu setup of bluray player and make sure resolution is on 1080i and not 1080p. I understand you will have to do this on another TV capable of 1080p or if your bluray player has a composite output (yellow single rca) then hook that up as it may be active at the same time into your AV in on the TV. Once you have picture, then you can enter the setup menu as I have indicated above. I hope this solves your problem.

I found R3 on the original board to be open, along with reading an open on CR1, D5 and D6. All the other transistors and the transformer check out. The only thing I have to do now is find out the specs of the diodes. The replacement board also had CR1, D5 and D6 open (R3 was OK). There had been some threads on various locations where remanufactured boards had bad components (the transistors were changed but not some of the other components).

Check the lamp again it might have broken, that or some component on the power board has died.

On Mitsubishi RPTVs there can be 3 dots on the front and how/when the blink can be interpreted as codes. Do you have a POWER, a LAMP and a TEMP light on your TV?

On the front there should be a panel you can open if you dont have a remote. On that panel there should be a reset button.Just press it while the tv is on.

This is a common symptom for the lamp being burnt out.The TV set detects that and goes on a safety mode.The lamp part number needed for this TV model number is TB25-LMP you can find this lamp on various online stores.

I have the same problem with my 65HM117. Funny, but it started just when I was getting a FREE repair for a Samsung LCD tv with bad caps on the power supply about the same age as the 117. The problem according to Samsung tech (who was kind enough to look at it while he was here) is the DMD (digital mirror device) chip, the "processing" part of the DLP (Digital light processing). Suggested I call Toshiba. Toshiba rep, obviously not in the USA, told me Toshiba doesn't make DLP's anymore "because of all the problems." They apologized repeatedly, repeatedly pointed out the unit is "out of warranty," but NO help or recal even though they know they built a product with defective, unreliable technologyl. Bottom line, Toshiba lost a customer but SAMSUNG has one for life! I'd repair it, but can't find the part number for the board with the DMD...

You need to replace the color wheel.Unfortunately they do not sell that part you need to buy the complete Light Engine or a new TV.
