JVC AV-27230 27" TV - Won't turn on - repair guy says parts no longer available

He says it is a high voltage power supply and that part is no longer available and he can't find one anywhere. He offered to "dispose" of the set for me. Does this sound right.

    For a while I noticed that it took longer and longer for the set to turn on. Fearing that it would go out completely I just left it running all the time!!! Yesterday, by mistake I hit the wrong button and sure enough, it won't turn back on. You can hear it making some kind of noise, (like its trying to turn on) when you use the remote, but otherwise, nothing. The set has a beautiful picture. I just can't get it to turn back on. The set was my mother's, who passed away so it has a little sentimental value too. I would really like to get it fixed if possible but not if its going to cost an arm and a leg to do it.

He probably means flyback transformer. They are harder to find unless you are a service provider. Then they have access to these parts. Generally it's a cheap part, but often servicemen can mark it up quite a bit. Try another service guy.

Only standby,won't start


Look to the High voltage circuit and also inspect the circuit board for any cracks or broken solder connections, unless you have a meter and can find a schematic it may be cheaper to replace the set than fix it.

Power on for a few seconds then turn off


Tv is going into x-ray protection mode. Check power supply voltage, make sure it's not too high. 160v dc across main cap, do not use chassis ground, use cap ground. If too high, something is open. If too low, something is shorted in power supply. Check voltage regulator ic.

I have a JVC model available27980 that absolutely will not power up. I checked the fuse inside, any ideas?


Replace the SMPS (switch mode power supply) STRF6626 regulator. This is the part which supplies multiple voltages which ranges from 157 V to as low as 16 V. Any one of these voltages could be disrupted. So instead of trying to repair it, sensible thing would be to replace it.

I am watching my 14 days old JVC 21"TV but


Hello
Your TVs power supply regulator section has got some trouble with it, that is why power indicator doesn't light up. You have purchased it only fourteen days back, surely there will be warranty for it. Do not open the TV. The company will give no concession if the set is opened. Send it to the authorised service center and get it repaired. Some power supply faults may fatal, and may have to spend more. Since your TV is a new model, spare part availability in the open market may be difficult. Send it to them and let them do the work. OK.

Fuckin jvc tv will not turn on and its really


Try to unplugged to the power outlet for 2 minutes, and then power on. Or for the meantime if it have protection circuit like surge protector disconnect that for the meantime. And then power it on.

If not there's maybe a high voltage circuitry problem if this is a crt type tv.

Jvc tv av-32d502 timer light is flashing will not turn on


Hello, I am a tv tech. I worked on a JVC AV-32D502 today. Problem: led flashes / no power or picture at all. Same as trobertson52's set. The microprocessor is bad in my machine. trobertson52, if your sets' relay does not click when the power button is depressed you most likely have the same problem or the standby power circuit is at fault. That circuit supplies +5 volts to the micro.

Edtal you have a different problem with your machine. Your machine is going into shutdown. A number of circuits could cause this and would need to be looked at by a technician to determine exactly which circuit is at fault. High voltage transformer (HOT) \ Vertical Circuit \ Power supply are the most likely causes.

JVC AV-35750 TV


I changed capacitor C926 (1000Uf 16V) on main board. It solved the problem. I went with 1000uF 63V as it was readily available...it's okay to go with higher voltage. It was hard to fit it on because of the larger size but it worked.

Problems with JVC AV-32WR4EK


This could denote a power supply problem. or overcurrent protection due to a component going bad. If you do not have electronics experience, "DO NOT TRY TO WROK ON THIS SET" people have been seriously hurt trying to repair TV without knowing the basics of electronics. If this is a power supply problem it may be the HV supply and the switching power supply (IVHT based) or the low voltage starter supply. In both cases I would advise you taking it to the shop for repairs.
