I have a 65hm117 tv. It has white spots and every day more spots ap[pier. What part do I need to replace.


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...

Distorted picture


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 overs. To get fixed either call in a local TV repair company or goto sites such as Tv Repair Kits to get a repair kit with instructions. Here is there link.

They have put together complete kits for most models that include the parts, step by step photo instructions, repair assistance, etc.

Sony e55a20 tries to turn on then flashes pwr light in sets of 6


Really sorry to say but you need a tv repair man. This unit has something wrong internally. Also there is usually a reset button on the back of the tv. This is your only other option. try resetting the tv, if there is not button on the back hold the power button for at least 1 minute.

Samsung le32n had it for 16 months came down this morning blue light flashing on bottom of tv but no picture or sound. Tried swapping cables, sockets, leaving it off for a while nothing helps


Those Samsungs and most other HD units can fail within 6-18 months of purchase.. I would contact Samsung and go up the corporate ladder for help. Otherwise you may be looking at a repair bill that is as high as the cost of new unit.

Samsung hln4365w - no pic. or sound. it whistles a few times when powered on


We have the same DLP set and had the same problem. The Color Wheel, P/N BP96-00250A, a $200 part needs replacement to eliminate your problem.

TV Shuts off by iself!


Don't feel bad about Mits. All the projection companies and all the new TVs have markedly poorer reliability than the good old CRT types. You should see all the class action lawsuits against even some of the best companies!

The power supply section is not working.
Common possibilities are:
- Convergences amps have failed overloading the supply
- High-voltage section (flyback transformer) has failed
(happens sooner or later, about 8 years typical))
- CRT tube has failed overloading the supply
- Power surge has popped the power input circuit.
(Fuse, rectifier diodes, turn-on relay etc)
- One of a hundred of electrolytic capacitors has failed short overloading the supply. They dry out with age, are cheap to replace, but hard to find which one it is.
- Or any of many other possibilities.

In short, you need a experianced tech to troubleshoot this.
