Hello

If the tv clicks SEVERAL times like it is trying to start but just cant make it over the hump this is "GENERALLY" a power supply problem. Bad Caps tend to make this happen and are fairly easy
to change by someone with a little know how. However, the bad caps could be hiding a larger
issue that only someone who is skilled can really troubleshoot.

If your tv is suffering from a powersupply many times they can be purchased on ebay, or sometimes you can find them totally rebuilt.

I hope this helps

u are getting problems with horizontal driver trans former
u have to replace it. some time it works normally when
copper wire windings get connected.

you may need the digital converter from radio shack or best buy

You will need to replace the transformer on the power sector. it has failed.

You almost certainly have a bad picture tube. The green screen was from one of the elements inside shorting out. The static sound you're hearing is the high voltage arcing out through the end of the picture tube to other parts inside the set. It's more economical to buy a new TV than to repair this one.

Sorry to have such good news, but this is one of the ways a picture tube can go bad, and it happens quite often.

Hi..i have the exact same problem. Did you find a solution for this? Please let me know.

Have you tried to access the menu features and tried to retune the stations on digital, or are you hooked up for analog.
If you don't know about what i speak, give me a yell. [email protected] I believe my remote sensor card is bad. While this might explain why you can't turn yours off, it would not explain the blank picture. If the menu does show, i would think the picture tube is O.K. if the menu does not show, there are some other things to look at.

Ts it in video mode?

i need the make and model of your television.. usually the red light blinks out a code. i need to know how many times it blinks as well. so i can find out what code it is producing.

Try to check the power supply output side where anything could came into contact with positive and negative line for which when you press play button then it shuts down.

RCA video cables handle analog signals. HDMI cables carry digital video signals. You need a converter. If you are using a component video converter, check if you swapped two of the three RCA video cables. (There are some A/V projectors that can do the translation of RCA and HDMI internally. Most TVs do not.) I hope this helps. Cindy Wells (One of my family's TVs used a dongle to condense the analog video signal to a single port, swapping blue and green gave a black and white output, IIRC.)

Most modern tv remotes are not normally designed to be repaired. You will possibly need to replace it. there are plenty of cheaper after market version that will do the job just as well. Your other option, and yes I know this is a silly answer, when you want to mute the TV is to simply press the volume down button to zero then turn it back up when you want sound.

you will need to rind RCA to whatever input is on your tv google RCA to HDMI copy and paste link for manual https://www.manualslib.com/manual/313476/Rca-Vr677hf.html#manual
