    Hey I've got the same issue as you do, tv whines three or 4 times, but
    then I get double solid reds, I even have the new 5kv bulb but now I'm
    wondering if the old bulb is good. Did you ever end up finding a
    solution? If so I'd love to hear about what you did. Also do you have
    any idea what is what in the back of the RD65, I'm pretty computer
    savvy I can build them and what not, so if I just knew what was what, I
    could probably replace the part that it needed. Any assistance you
    could offer would be greatly appreciated!! Thanks!

In most projection televisions if a solid light comes on there isn't anything wrong the bulb there is a problem with one of several cards in the back of the television. I'd check for over heating damage on your imput cards, the Controller card that is connected to said input card, or the relay card that controls the tube output. Keep in mind you did order a part off of Ebay which is untrustworthy in and unto its self.

TV shutting down, lamp and power light blinking


I would try a new lamp. Lamps have varying qualities & usage conditions may cause varying life spans.So, even though the lamp may be 1 year old I would try a new one first.

I have a Sony KDF-55WF655 and the bulb blew out and I smelled something electrical burning.


3 blinks is indicating that the lamp door cover isnt making contact so the lamp door cover is either attached wrong or the switch is defective.

Changed lamp green light comes tv plays for about 1 or 2 minutes tv goes blank red flashes 3 times.


Not 100% sure but I am currently looking into this. 2 things it might be which are most probable. I replaced my lamp a few years back with no issues. This time around I figured I'd be proactive and bought a new lamp as my current one was going dim. Not unusable but I could tell. Lamp arrived and I put it in. Started up, great! Then after a few minutes it shut down and the red LED would blink 3 times. I removed the lamp and replaced it after unplugging the tv and turned it on. This time it ran about 20 minutes and same thing! Tried a third time and had the same thing. So I put the old bulb back in, and this time it didn't even turn on! I removed it and with a flashlight looked in there. There are two safety switches. The first is a very small pressure switch at the base of where the bulb interfaces to the TV. That switch ensures the bulb housing is seated. Secondly there is a switch in the rear side where the second door with the lever lock is. When you rotate it the switch is engaged. I replaced the housing carefully and made sure everything was tightly seated. The tv has been on for about an hour now no issues with the old bulb.

I have two theories and am leaning toward the second one I will suggest. One is that the bulb is somehow overheating as it is newer and brighter, or is somehow defective. The other theory is that as the bulb heats up the switch might be getting dislodged. I am leaning towards this given that it is working with the old bulb. But I am not certain. Soon I will try the new bulb again and may even attempt to slightly bend the switch out a little so that it is easier to engage.

Samsung 50" DLP - Lamp Light Blinking after bulb replacement


Listen closely. The tv should make a high pitch whine as it turns on. If it does wait and see if it tries this a few times. If yes then check the bulb, I have seen cases where the lamp shoves the power connector back into the set. If the tv starts with a grown or heavy vibration noise, then your color wheel may have broken and needs replaced.

Panasonic PT50LC14 Power issue


We have a PT-50LC14. We replaced the lamp 6 months ago with a TY-LA1000 bulb we bought from a company online (not directly from Panasonic) and it worked for 6 months. Then the TV started turning off on it's own...sometimes it would not come back on for an hour or so. We called the lamp company and we luckily had 1 day left on our 6 month warranty!! They sent us a replacement bulb and the TV would never power on. It would try to power up, but the bulb would never ignite. The power light would flash and then the lamp light would flash every 5 seconds. I had a friend that has the same type of TV and she ordered her bulb directly from Panasonic. I borrowed her lamp and it powered right up. We then called the online company and they sent us yet another replacement bulb, and I tried it today and it works. It seems like these TVs are very particular about the type of bulb used. Next time, we will be ordering ours directly from Panasonic and just paying the extra $100. We have been without our big screen for 2 very long months! I had called a local tv repair shop, called Panasonic directly, and read through countless internet forums, and I thought we were going to have to replace the ballast or get a ballast repair kit and start messing with the circuit board.

LG 44SZ8D not turning on


The red light indicates the lamp is burned out. A new one is $100 to $200.
Depending on whether you use the old housing or want to order the lamp and housing together. There are lots of sources for this lamp online.

Once the lamp is replaced, it will be good as new and the lamp will last aprox. 8000 hours.
