Question about Samsung HL-T5076S 50 in. TV

Open Question

When I turn on my TV I get a high pitched beeping noise coming from the back by the bulb. The far right green light flashes and the TV won't turn on. After it restarts a few times then all lights flash. I replaced the bulb with a new bulb from samsungparts.com. It matches the existing. After watching TV for 3 hours. The next time I turn it on it did the same thing. High pitched beeping and then 3 flashing lights.

SOURCE: red light flashing 4 times, tv turns its self off

Start by removing and inspecting the bulb. The filament you're looking for is encased in the glass tube in the center of the lamp itself. Kindof difficult to see unless you're at the right angle. 9 times out of 10 that solves the problem. If not move on to the ballast, the small circuit board directly underneath the lamp housing.

SOURCE: New Samsung Tv High pitched hum

Don't know if people are still having this issue or not but figured I'd post what i went through to help anyone that has. My LN-T3253H tv as out of warranty when I finally got around to calling Samsung. They flat out lied about the commonality of this problem and I convinced them to at least pay for any parts. Problem is the labor of a technician would be around $150. So, I bought the new power supply from Partstore.com for around $70. Just go to partstore.com and enter your model number and look for the power supply on the page. It took 3 days to get the part. It was very easy to replace. All you have to do take off the back cover of the tv (think there were around 12 screws all around the outside and one where the A/V connections are and pull off. Unhook the plugs going to the power supply and the four screws holding the board and then replace with the new board. So far, this fixed the issue. Keep your old board in case it starts happening again. You can probably have the old board repaired to fix the original problem since so many TV repair shops are aware of the issue. I am trying to find out from someone which specific capacitor or other piece is causing the issue and plan on fixing it myself. If and when I do, I will also post that.

Make sure you give Samsung a ton of grief when you speak to them and see if they lie to you also. I had just bought two of the new Samsung LED TV's for my media room. They work great but I returned both because of Samsung's refusal to fix my LN-T3253H and I will never, ever buy Samsung products again.

Samsung HL-T6756 DLP TV Standby/temp light flashing and tv won't come on. I have replaced the lamp and the fan is working. Any suggestions?


Remove lamp and inspect the color wheel to see if missing pieces or shattered---it will also just before failing give a high pitched or fan like sound and if running too slow or not at all instant shutdown happens.

Its also possible if you bought a GENERIC bulb--and used original cartridge the new lamp is bad.

I haven't worked on an RCA DLP but have on Samsung DLP, based on your description it sounds like the color wheel is bad. Take the back off and turn on TV make sure its not a fan making the noise ,but most likely its the "wheel" it is inside the light engine probably right next to where the lamp is plugged in. If the whine comes from this area definitely the wheel.

All three lights turn on like normal and then nothing


Depending on the pitch. humming noises are either a motor ie: fan motor or if it is very low a defective capacitor . Since you have the yellow band and the high pitched beep my fist thought is somthing defective in the power supply. Take it to an authorized servicer.

Does the set make any sounds. DOes the front green led light or flash when you try to turn it on.. if not then it could be as simple as a fuse, if it does flash then it can be many problems
