Question about Televison & Video

Should I change the bulb?

I have a 52 DLP Toshiba TV, for about a week when I turn it on it makes a sound like it's got an open circuit (makes a arching electric sound) Now I pulled out the bulb, looked at it. No wear or tear that I can see on it, bulb is fog free. The only thing is it is 5 years old, and I do watch a lot of video and TV. Could the bulb have some internal circuit burned out or is the whole dang TV just a huge paper weight now?

Hi MovieJunkie9,

I would first recommend having a diagnosis done by a Toshiba authorized technician. Bulbs for projection televisions are typically a costly part, so I would not advise replacing it if you are not sure it is needed.

Second, make sure that your product's manual lists the bulb as a user-serviceable part and gives specific instructions for you to change the bulb to make sure you do not do any damage to your unit.

So long as your manual gives you instructions for changing your bulb and the Toshiba authorized technician diagnoses that the bulb is the issue, you should be able to go ahead and change the bulb yourself.

Thank you,
Jason,
Go Ahead. Use Us.

Periodically my 52HM95 would have some little electrical glitch where it would not come on when I turned the tv on. I would have to wait a little while before I tried again, or I could shut the power off...


I have a similar DLP TV. If you losing your new bulbs that quickly there is likely a problem with cooling. There is a fan that keeps bulb cool. Make sure the fan is working and there is nothing blocking the air passages. I have not had a problem with my fan but you should be able to find a replacement at Radio Shack or a computer/electronics store like MicroCenter. They come in standard sizes just make sure the voltage is correct typically 120 VAC or 12 VDC.
I have had the computer inside crash such that the sound would work, the bulb would come on, put no picture. Fixed by unplugging the TV for one minute then plug in and turn on.
The bulb repeatedly goes through its startup cycle but never comes on. It tries about ten times then stops. Fixed by removing the bulb housing and firmly tapping it on a counter top ten times. This was at Toshiba instructions over the phone and it actually worked.

Toshiba 52HM84 DLP TV with new bulb but the lights keep blinking


They exact way the lights blink are telling you what the failure is. If the tv is firing the lamp and the lamp is bad, you will hear a buzz sound for about 1 second. The tv tries 8 times before it gives up and spits out the lamp error. Check the user manual for led diagnostics. If you put in a new lamp but still have issues, you've likely got a bad ballast (most common on this model) or colorwheel (less common). Both are part of the optical block (light engine) and I don't believe they're available as individual components from toshiba.

You have bad capacitors in the power supply that took out the regulator, or the ballast circuit is defective. Not really a repair for the novice. Good Luck
