Unplug the tv set for 30 seconds, plug back in and turn set on, if the problem still on and you are sure its not something with the remote (like bad batteries) call for service. BUT If you're NOT still under warrantee you should at least open the TV and check the board where the components are mounted and resoled any that look bad. Brief power outages may cause power problem. If you are using a surge protector, try connecting the set directly to the wall outlet. In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint at the horizontal drive transformer. All can be replaced at a local electronic or hardware store and they're easy to replace good luck!

Samsung HL-R4266W 42 in won't turn on


Initially, have you tried a full hard reset? If not, pls unplug from the mains. Most current devices would reset and revert back to factory default settings (assuming no internal hardware fault) when unplugged for a considerable period of time (from a few minutes to a couple of hours).

Additionally, have you tried powering the unit using another outlet?

Pls post back for any development(s) or even the lack of it.

Hope this be of initial help/idea. Good luck and kind regards.

Thank you for using FixYa.

No picture and the power light blinks

A red blinking light could mean that the lamp timer is at it's limit and it is time to change the lamp. You will also have to reset the lamp timer by pushing and holding down 2-3 buttons on the tv or remote. Refer to your user guide for the proper way to reset and or change your lamp.

I have RCA HD50LPW167 DLP TV with NO Sound and NO Audio. The LED blinks when I turn the TV on but that's all it does. Took it to the local RCA authorized repair shop and they told me that the digiital...

Still sounds like a lamp:

TV won’t turn on
• Press the TV button or ON/OFF button while remote is in TV mode and there’s a source of power to the outlet or outlet strip.
• Make sure the TV is plugged in.
• You might have tried to turn on the TV during the lamp cool-down. Wait a few moments and the picture will appear.
• Has the power light on the front of the TV been blinking for one minute? If so, the lamp may be dead. Refer to the Power indicator
is blinking or fl ashing
section below for more information.
• When you fi rst plug your TV into an outlet, the Power indicator on the front panel will light and blink for approximately 30 seconds
and then go off during the initialization of the TV. This happens only when power is reapplied to the TV. The TV can only be turned
on after the Power indicator goes off.
• Check the wall receptacle (or extension cord) to make sure it is “live” by plugging in something else, such as a lamp.
• Something might be wrong with your remote control. Press the POWER button on the front of the TV. If the TV turns on, check the
remote control solutions on page 84.
Remote Setup might be set to the wrong option. Press MENU/OK on the front panel. Select Connections, then Special Features, then
Remote Setup. Choose TV (default).
Power indicator is blinking or fl ashing
If the light blinks 5 times, pauses, and blinks again 5 times, the lamp is trying to turn on. If the TV doesn’t turn on after 5 minutes and
then the light blinks steadily for one minute, one of the following options is possible:
• Lamp door may be open.Face the back of the TV. Locate the door at the bottom of the TV and close it. Turn off the TV and turn
back on. The lamp should turn on.

You can easily replace the lamp yourself by following the lamp replacement instructions. If your TV is still covered by
the warranty, call 1-866-723-6486 to receive troubleshooting assistance and a lamp replacement.
• If your TV’s warranty has expired, call 1-800-338-0376 to purchase a lamp replacement.

To order the correct lamp, you’ll need to know your TV’s model number, serial number, and lamp type—this
information is listed on the Service Model Number sticker (example of the sticker is shown above). Face the back of
the TV. The sticker is located on the right side of the TV.

Hope this helps :)

No Picture or sound

The lamp cover door was not secured tightly. Door does not "push" shut easily. Got a little rough with it and latched it shut, then the tv worked fine.

No picture or sound mitsubishi 62525

Capacitor failure is the most likely scenario the FMT ans Signal PWB would cause the picture interference and the power pwb would cause the lamp light to turn red and give a 34 code when the device/ input and menu buttons are pressed in together and held for five seconds. That chassis has issues with every board in the chassis having failed capacitors you can get repair kits for the V26 chassis at the follwing link that come with instructions. Your model is the V26 chassis. Heres the link.

No Picture, power button blinks 5 times and just clicks

If you dont have the manual, download it from internet. It should tell you what the blinking light is indicating. My friends tv was blinking 3 lights around power button and the manual I downloaded correctly stated it was the lamp that needed to be replaced. I also found some other interesting info via the internet. There is a way to get into the Service Mode of a Samsung TV. Try doing a Google search for Service Mode for your model... Good Luck. PS the lamp itself was pretty expensive but installing it was not hard to do.
