My Mitsubishi tv WD 73734 won't show a picture you can hear sound and it powers on and off lamp light red and timer lighter blinking


No TVs will behave that way due to a timer. TVs only will display a nag screen telling you to reset the timer. If your lamp is more than 2 years old, it is suspect of failure. Be sure you buy a lamp with an Osram brand or Philips brand bulb inside. Any compatible(knockoff)lamps will not perform as they should. Mitsubishi DLP TV Bulbs
These folks sell original Osram bulbs in their lamps and they have a 6 month warranty. I use them myself for repairs and really have had great experiences with them.

Have a mitsub. WD-73734 working fine this morning with white and black dots - replaced the chip and now the tv won't turn on, green light blinks raptly then the lamp light starts to blinks red/orange


Somehow--the lamp is not firing. Before you go get another bulb--check ALL of your work, and make SURE no connectors to the ballast have been left off or pinched somehow. It is easy to do this. Also, make sure the lamp door switch is making proper contact with the tab on the lamp door. You have already fixed a real problem with this set--do NOT give up so easily now!! ALso--make sure all fans are running. If ANY do not run--it WILL shut down. ANd make sure the color wheel connector has not come loose or been damaged somehow (this will be between the engine and the lamp area--likely have a "hump " raised in the light tunnel betwen the lamp and the engine--this is where the CW is). Even IF the ballast died (NOT likely at all), you can find one on ebay for under 100---and this set IS WORTH the repair. You will NOT be satisfied with some crappy flat-panel as a replacement.

TV will not turn on, it just sets an makes a clicking noise like it is going to come on and will not. The red light under lamp is on.


Sounds like you need a new lamp. Try re-seating the lamp first. If that does not work you might need a new lamp.

It could be the lamp, they have an approximate 1 year life depending on conditions. If you bought the TV new, it has a 1 year warranty and labor you might want to contact warranty support. They will send you a new lamp.

To Receive a Replacement Lamp Under Warranty
Call (800) 553-7278. Please have model number, serial number, and TV purchase date available.
Important: All lamps replaced under warranty must be returned to Mitsubishi where they will be inspected for defect
verification.

Appendix C of the manual describes how to change the lamp. Handle with care (avoid fingerprints on the new lamp). Make sure the TV is off for at least an hour before starting.

I hope this helps.

We had the same problem. One place changed the lamp but they couldnt work out why it was red and lots of shadows. Next mob said that it was the component so they replaced that. From the 28/4 till end of Oct, the TV has now switched itself off and wont come back on. Both places say its the lamp - however I cant see how in 6mths it would run out again. The people who replaced the lamp dont want to help, just said they will put in a new one at $521. This TV has cost us so far $1100 in repairs and it's only 3 yrs old. Not happy. The DVD recorder broke within the first year, the set top box broke in the 2nd yr and the surround system blew up (yes smoke appeared and we were lucky we were home) on the 13th month. Mind you our LG comp screen also shut down on the 13th month. Never again will I buy LG

Problems with brightness on the hitachi 50v810


Yes, they dim as they age, and you've done well to get 3 years out of one.
Projection TV makers charge an arm and a leg for their replacement lamps. They make it easy to do but as a result the custom lamp assy is expensive. The trick is to just buy the bulb for your model TV from any number of us aftermarket sources at a fraction of the lamp price and install it in the old lamp yourself. really easy.
