Question about Televison & Video

1 Answer

We have a Toshiba 42HM66 DLP. It is at least 3 years old and the lamp had never been changed. Lately the picture has gotten darker and once the unit is on for awhile the picture starts flickering and colors are not right. We assumed it was the lamp. Changed the lamp and still the same problem. Called Toshiba, they could not help but said picture flickering is not a symptom of needing a new lamp. They suggested we call a tech and they gave us a reference. The tech came out and agreed the picture was bad even though a brand new bulb was just installed however it did not start flickering while he was there. He suggested that when it does to call him. He has never seen a problem like this in this model before and his only thought was it was some part that would cost a few hundred dollars. Anyone else have any idea? The owner of this TV is terminally ill and I would hate for her to have to buy a new TV at this point.

    OK. Please bare in mind I do not know what you mean by Inverter or capacitor. How to I confirm it is not one of these things? We also have a Roku box connected to the TV and when that was on the screen still flickers. However, when I have the menu up, the menu itself is not flickering but the background is.

    Great I will check and see. Are these expensive parts to replace?

    OK. The repair man said that these TV's do not have an inverter because it is a DLP. But he still hasn't figured out the problem. Maybe I orignally posted this in the wrong area of this website. However, the flickering seems to have stopped but the picture quality is terrible. This is with the new bulb installed. What besides a bulb would make the picture so bad? You can watch the TV but there is no HD quality that I can tell. The picture is either too dark or too light. Not crisp.

Check if the flickering happens when you have the menu up on the screen. If the menu does not flicker it may be the source of the signal or the connections to it or probable the board where the connections are terminating at. It may also be a problem at the inverter. It may be due to a capacitor that is leaking or swollen and is starting to go bad.

    I see. The inverter is one of the boards on the tv but replacing or taking this off may need a specialist as for the capacitor it looks like cylinders and may have different colors with two legs attached to the circuit board. If they are leaking or swollen they need to be taken out. The technician may not have inspected them.

    the inverter may be pricey but the capacitors, they are the cheap ones the power supply circuit may also be the culprit. It is the first circuit after the power cable. Check for the capacitors as well. The power supply circuit may be a little cheaper than the inverter. Check first my first suggestion if it happens on the menu... thanks

    did you notice the same problem in all inputs, like DVD players, using the round RCA connectors or TV connection? For the dark or light picture how does adjusting the contrast help? Did you notice the fan turn on or off? I am thinking that its could be a convergence IC issue (one of the flat things on the board with many legs on it) or still a power supply issue if the fan keeps on turning or there was a voltage drop or surge if the repairman measured them.

Picture is getting darker


Many of these DLP sets the picture gets darker right before the lamp fails.

Average life of the lamp is 2,000 hours----about 1 to 2 years of normal use.

If the lamp has not been replaced for a long time it is first suspect in this case.

Let me know if you have questions.

Toshiba M#42HM66 First lamp blew after approx 3 years Bought new lamp and it blew after 3 days. Could I have another problem other than the lamp


Yes usually for a lamp to fail there is a drive problem, one must always fix the causative problem, behind the failure, or as you have seen it will simply reappear. The most common problem is "Dirty Power" to the lamp. But I think it is a problem for the serviceman/center.

Picture getting darker over the years


It could be your Light Engine. However, I would first check a few things:

1. Make sure your Low Power/Lamp settings are adjusted so that they meet your brightness needs.

2. Make sure you used a Mitsubishi original lamp, as generics get chewed through fast and hard.

3. Try another lamp; sometimes you can get a bad one in the bunch.

All those things don't work, consider a Light Engine ($400 + for parts; $300+ for labor)

14 MONTH OLD TOSHIBA TURNS OFF BY ITSELF


I repair a lot of these and a average tv lasts like 3 years . It is not like the old days. I suspect the lamp or fans or therm protector.

I would call a local tv shop see what they charge for estimate it might be worth his estimate to find out what it is.

You need to replace the lamp in this set. The "pop" you heard was the lamp popping.

Picture seems to be alot darker than before. toshiba 62hm95


I just replaced a lamp in a Sony LCD projection that was just over a year old and it was bad. It was a VERY dim picture. You have a DLP but, in either case a dim or dark picture is almost always caused by the lamp.
