Your hookup is correct- Your VCR needs to be tuned to channel 3 or 4, to match the cable box.

Also, the VCR channel output needs to be matched to the TV. If VCR menu options are displayed on the TV then this part is right. If not, then set either the VCR or TV to the correct channel.

Hi Pukkaca

Sounds like the child lock is on. Hold the play button in for 5 seconds on the remote. IF that does not work, hit me back here and I will find the one that does.

regards
Graeme

yes, you need to use an Audio/Video cable (red, white, yellow) to hook to the TV. I've never seen a VCR that doesn't have coax connectors for the antenna input and TV ouput, but maybe the new ones are starting to leave that out. Normally, you run the antenna or cable coax into the VCR's input, then run another coax from the VCR output to the TV's input (or use an A/V cable)

This is easy in a nutshell. from the cablebox into the VCR RF connection (ant in) then from the VCR RF into the TV RF in. The from the DVD composite video out and audio out into the VCR composite video in and audio in. This make the VCR the hub of your setup the VCR should be set to channel 3 and you can switch between the VCR and the DVD by using the VCR remote. Now for the cords: 1) Cable to VCR RF = Coaxial 2) Composite Video and audio out = RCA patch cable 3)Composite Video and audio in = RCA patch cable That is it. If your TV can support multiple inputs then use it as the hub. Cable Box to VCR RF (Coax cable) VCR to TV RF(coaxial cable) or VCR to TV Composite video, or TV Component Video (RCA Cable) DVD Player to Composite video, or TV Component Vido (RCA Cable), or Svideo (Svideo cable)

Use code search on your URC to find something that woks. If a search through all Sharp codes stored in the URC fails, try a different one.

Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. https://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty. It seems that your TV has philips maun board in it. Some sharp sets uses Philips Circuit and main board.
Counting of number of blinks to Philips TVs is entirely different to that of other brand TVs. It is not a direct count procedure. The site have details about how to count the number of LED blinks [Fault Codes] to Philips brand TVs are given; along with details of the faulty circuit location.
