Digilogic digital set top box (DSTB1000) - No picture

I turn my TV to AV channel and all I get is a black screen. No picture, no sound. Standby LED is lit green. Function LED is lit red. The remote batteries are fine as I can still turn it on and off using the remote.

All of the lights are occasionally going off for brief periods too....i.e. turning itself off and then back on again.

We have been having some bad weather but surely that wouldn't cause this would it?

Is it doomed? I have had it for a while.

Hello Suzid, It looks to me like you have a possible power supply issue (poor brightness on screen, shrinking of the picture, and initially no picture) This problem may put you in danger of electrical shock, so I would suggest that you not try to repair this set yourself. I would suggest that you take the television to a television repair shop.The power supply issue could be a low power or a high power supply problem.

Alba TVs are manufactured in Albainia and the service info is next to impssible to obtain. I would try to troublehoot the deflection circuits. Possibly horizontal output or one of the regulators.

Replace the horizontal output transistor (Q502) and check the electrolytic caps in the vicinty, unsing an ESR meter. PLEASE NOTE THAT THE TV TUBE MIGHT BE CHARGE WITH ABOUT 27,000 VOLTS.

Okay I've purchased a 40 inch tv today and how do I reset everything?


From the User Manual, page 35 (page 36 in the .pdf file):
Return your settings to default values When you return picture and sound settings to their default values the
channel installation settings are not affected.
1 Press MENU on the remote control and then use [the arrow buttons] to select [Setup] > [Installation] > [Reset AV settings] > [Start now].
2 Press OK to reset the picture and sound settings.
3 Press MENU to exit.
You can download a copy of the manual from 40pfl7705dv_f7_dfu_aen.pdf http://download.p4c.philips.com/files/4/40pfl7705dv_f7/40pfl7705dv_f7_dfu_aen.pdf

You may also want to look at "Update your TV software" on the following page of the manual. Updating is not always necessary, unless the update fixes something that bothers you or provides an improvement you want (if it isn't broken, don't fix it). As of this writing, there are two sets of fixes (copied from the "Firmware Upgrade Readme File" at Software & drivers):
Software history:

Version: Problems solved.

PHL-0DA_710_0 - Momentarily looses audio after channel change.

- Time shifts one hour when changing from "Auto Clock" to

"Manual".

- Enables Philips Wireless Media Connect.

PHL-0DA_713_0 - Clock does not keep accurate time.
You do not have to apply both updates; everything is included in the latest one.

I have a Gold Star TV, several years old, that is stuck on a black screen with AV on it. I pushed the wrong numbers to change the channel and cannot get it to f\go back to tv mode. Can you help me?


If you have the remote, press the AV/TV button. If you have no button with AV/TV written next to it, look for a symbol that is the outline of a TV with a small + sign in the corner. Or, worse case simply press each button one by one, until you find the one that switches the channel. If you bring up something on screen you're not sure about, turn the TV off and back on again.

Toshiba t/v model 155R9B how to set channels to correct numbers The channels are coming up to the wrong nos. for instance BBC1 could be on no. 3. how do i set them to correct channels?


Digital tv channels use analog carrier frequency of old system then changes to digital tv numbers later in the tuner memory. Leave tv on or standby at all times to have tuner set the digital tv numbers in its memory. You can reset the memory by pull the plug on the wall for 5 minutes then reconnect to the wall plug.

How to connect settop box to tv with no avs


You will have 2 UHF plugs on your set top box.. One for input (aerial) and 1 for output (TV). Connect your main aerial to set top box UHF input and connect an Output UHF lead from set top box to TV. Next switch on set top box and retune tv on a spare channel until you get set top box channels (good idea to switch on menu on set top box so you know you are tuned into set top signal )

My Screen Said "Are You Sure" and "Please Wait" and now, instead of "AV", i have "AV1" and "AV2" and my tv wont show picture from the dvd player OR vcr


You will need to go back into the menu and see what ia available in the video input mode. You may have switched the type of input you can use such as default or componts ect. If you have an isntruction manual, look in there or call the manufacturer, should also be in the instruction or user manual. Good Luck
