I have to say I have had NO issues with this TV! I replaced the Bulb once after 5 years.

I replaced the bulb only on my Toshiba DLP The bulb is a TB-25. This is the first time I've done a bulb only replacement. Supposedly there is a timer module that needs to be re-calibrated or reset. I don't know where the module is located. I see some vendors selling the bulb with the housing stating module included which leads me to think the module is located inside the enclosure the bulb mounts in, but I didn't see it. Maybe it's inside the plug attached to the bulb?
Anyway - I am seeking information on how to reset this so called module so that the lamp will operate. Apparently... -
Hi,
I have a LUMIMAN Smart Bulb that suddenly stopped lighting one day. The bulb is still detected in the app, but won't light. I've probed around and nothing seems to look off with any of the diodes, caps or resistors. The Bluetooth/Wi-Fi module seems to be working as it's still detected in the app. I even tried deleting and re-pairing the bulb (it didn't light, but I was still able to follow the pairing instructions), it re-paired fine, but still no light.
In diode mode, the LEDs all light up when probed so I'm guessing this means the LEDs themselves are OK. I was expecting... -
As the title.
I think these used to be sold in maplins a lot of years ago, it is an antique, but it's just fine for my needs.
It looks basic enough inside with large components so I could do a full recap pretty easily.
Any suggestions on what component would cause the symptoms of low volume output on both left and right rear speaker outputs?
If I turn up the rear gain level in the amp until the speakers start to distort it starts to distort quickly even though the speakers are still pretty quiet.
I thought I had dodgy speakers as I just fitted new old stock 6x9s in... -
TV was fixed just after removing Samsung's rear snap cover.
This curved TV's construction is rather interesting. When the snapped on back is removed, rest of the TV will relax the curvature. Top of LCD panel is loose as it wants to straighten out against the slightly curved bezel. Snapped back provide most of the curvature shape. So just simple disassembly of rear cover will allow the rest of the TV frame to relax its curvature. Thats probably what fixed it but no idea which connection. 4x LEDs are edge lit.
Maybe PSU->backlight connector didn't have a good contact?...07-23-2025, 12:34 AM -
I have a pioneer dvl-909 LD/dvd player from 1998. It has a light on the front panel that lights up when you play a dvd. I removed the bulb and it appears to be a tiny incandescent bulb. Its measures "open"/dead and the bulb is black like it's blown. The socket it fits into measures 5v. I've looked up the schematics and there's no indication of the amperage. I don't want to spend any money on new parts, but I have a pack of like 100, 3v, 20ma LEDs and I have various resistors.
Is there a way for me to determine the amperage going to the old dead bulb with my multimeter?
