    Anyone know a solution?

Troubleshooting switching power supplies just sucks, but there are ways of finding the fautly componets. In my case, a visual inspection found 2 bad capitors, the tops bulging open and oosing goo. If you look at the tops of any other caps they should be flat. You can also note faulty caps by discoloration of the circiut board itself. I had one other faulty cap on my supply that, by visual inspection had been running hot. After replacing the defective caps (Nichicon 105c) I went with an ohm meter, and checked the smaller transistors for faults. Q1 a very common transistor was bad (2N3906) with a base emitter short. In conclusion, it's the cheap caps that are at fault, sometimes taking the silicon with them as they short out. The unit is now working.
As an added note, I understand that there is a Radio Shack branded version of the HD3150 as well.

Is RCA TV Model L40FHD41YX9 a high definition tv ?


It has a 1080p display panel (Full HD) and also supports 24p for the optimum way to display Blu-ray. So in these respects it is a high definition TV.

The built in TV tuner may or may not receive HD broadcasts though. That doesn't change the TVs ranking as a HDTV. It just means you might need an external HDTV tuner to get the same kind of quality from TV broadcasts as Blu-ray and console gaming.

Hope this helps.

How to set a clock on a hd dual tuner dvbr dch3416


The clock should set automatically, synchronized with your cable provider's time. You can't change it, as far as I know. OR does it display the channel number and you want it to display the time? If so, go to your onscreen menu (home), choose setup, choose cable box setup, front LED display: current channel ----> current time.

Do we need to buy an antenna to get this TV ready for Digital TV?


LCD TV refers to the substance that creates the picture quality (it would be either LCD or Plasma or Tube) and HD refers to a crisp clear picture that can be attained. So your TV is an LCD (Liquid Crystal Display) TV that is capable of receiving and displaying HD (High Definition) Picture.

What you need to check for is whether the TV has a built-in Tuner. This will either be SD (standard definition) TV Tuner or an HD TV Tuner. The box it came in will tell you or you may still have stickers on your TV.

If it has a built-in SD tuner you will be able to pick up HD channels but in a lower quality. In this case you will only need to plug the TV into a Wall-socket antenna or rabbit-ear antenna.

If it has a built-in HD Tuner you will be able to pick up HD Channels in full HD quaility picture. Simply by plugging the TV into a Wall-socket antenna or rabbit-ear antenna.

If your TV does NOT have a built-in TV-Tuner then this TV is clasified as "HD Ready". Which means that you have to purchase a Set Top Box (STB). you can get either HD or SD set top boxes. In this instance you will plug the cable from the wall socket into the STB then from the STB into the TV using either an HDMI cable (as long as your TV has an HDMI input) or through RCA cables which will be coloured Green, Blue and Red (i think red)

By the Way - best picture quality is from a wall-socket antenna.
HDMI = High Definition Multimedia Interface
STB = Set Top Box
High Definiton RCA cables will also be refered to as YPbPr/YCbCr (depending on equipment)
LCD = Liquid Crystal Display (the method used to make the picture on your TV screen)

If you have anymore questions, ask away.

My thomson dti 6300 250gb free view box wont turn on


Emailed Topuptv and got this reply

Dear Sir/Madam,



Thank you for contacting Top Up TV.



Please note that we are currently aware of an issue affecting some Thomson DTi6300 boxes.

If your DTR will not come out of standby and is not responding to your remote control, please try the following procedures.


Step 1: Power cycle
First of all, remove the power to the box and wait 20 seconds before restoring power.
Wait while the box tries to restart and allow 2 -3 minutes for this to complete.
Try this at least twice.
If it doesn't go to the solid green light then proceed to the next step.


Step 2: Front Panel Reset

Note: This procedure will unfortunately cause you to lose all of the recordings that you have stored on the box. You will need to be able access the back of the DTR and the front panel buttons

1. Remove power to the unit by removing the power cable from the back of the DTR.
2. Wait 20 seconds and restore the power cable while holding in the standby/power on button on the front panel of the DTR.
3. Release the standby button immediately you see a light 'blip' on the DTR front display and then immediately press the following front panel arrow buttons in sequence Up>Down>Left>Right
4.The DTR will now show the Orange LED with the Green LED flashing until the format has been completed in about 60 seconds. The DTR will return to ON automatically.
5. If requested, perform a channel scan to complete the operation.


We apologise for any inconvenience caused. Our Customer Services department can also be contacted on 08444 159 159. However, please note that we are currently experiencing high call volumes and so may not be able to answer your call as quickly as we would like.

Kind Regards,
Richard

Combining output from dish home distribution with ota antenna


You should have your system setup in the following manner below:

You also will only be able to receive the HD locals with a HD OTA antenna. It is possible that you will need to turn the satellite off in this room to view the OTA's effectively.

Also you should use a splitter as depicted in the picture by the red boxes to combine signals of this frequency. The blue box is the diplexer on the incoming satellite feed and the black box is the seperator that most dual tuners use. If yours does not utilize this device you will have another cable coming from the outside of the house to the back of the receiver. The location of the ports on the back of the receiver in my diagram may differ in position on your receiver so obviously connect them to the proper port. I hope this ressolves the issue and there is no need to seperaate the signal at the remote tv as it will only be a duplicate of the same signal you have connected already as OTA and the TV2 backfeed are of the same frequency range.

Problems with subtly changing colors


What connection are you using, HDMI or component?

Also, on what source is the problem happening, through sat or through off air antenna?

If you're on HDMI I'd try component. Then, playback the affected video and see if it's reproduced w/ component.

If it's on ota only, you may have a loose tuner cable inside. It's easy to fix, you need a torx t-10 screwdriver. Unplug the unit, take the 5 torx screws off of the back cover, and on the right side you'll see 2 cables running from tuners in the front to a splitter that connects to the tuner for ota on the back right. Just make sure the connections are tight with your hands only, don't over tighten them. Also, make sure you don't touch the power supply when you have the unit open!
