I would say your set needs a service engineer who is familiar with this model/make, sets shut down for various reasons, under No signal conditions they will or if a fault causes this state. They react to faults caused by faulty components or solder joints that have become poor so switch off to protect themselves and more so you, heat can make parts fail. If it recovers each time then the odds are good it can be fixed easily but by waiting the fault may cause further component damage so then beyond repair. If it otherwise works OK and you can get it fixed then please do before the fault makes things worse.

Clicking sounds


You must obtain the service manual and identify the parts from the layout diagrams.  It is not an easy job and is even one that advanced tv techs have trouble with.

You may want to spend the money to have a qualified expert do the job because the set should be analyzed first to make sure you know what is causing the problem.  I can only be about 70% sure by long distance diagnostics!

My tv cuts off then it won't come back on when powered on the power button light just keeps flashing. After unplugging tv for 20-25 mins it will come back on


CRT screens use a vacuum tubes for displaying purposes. These tubes warn off through time and use, with symptoms like colours fading out, late responce on start and even quit doing what they suppose to do.
My solution is to replace the warn tube with a new one,if you really want to keep this screen properly functional, but this could get to much trouble and cost maybe.

My 19pr15 c122 will come on for a second then shut back off just wondering if its something fixable or should i just trash it


It's seldom the parts that cost much, it's the labor to figure out which parts are causing the trouble that make TV repairs expensive. Many things can cause a TV to behave the way you describe, so I can't point out one or two specific parts. Even if I knew exactly what was causing the problem, you might have trouble getting the parts or lack the tools and soldering skills to replace them. It's possible to do more damage trying to repair a set without some experience. So while it's certainly fixable, it's probably not economical for this small of a TV. You could easily replace it for the same cost you'd likely face if you have a technician service it. Use this as an excuse to find yourself a new TV.

I have a Sony Wega KV-34HS420 TV that takes several tries to turn on. When I push the power button or remote power on I hear the normal click and the sound comes on for 3-5 seconds but then I hear a second...


Since the set appears to "recover", it suggests either a poor solder connection or bad cap somewhere in the power supply. The 7 blinks indicate the problem circuit is in the horizontal area. Check the regulator (STRxxxx) IC in the power supply. If you do not have experience working with TVs, please refer this repair to a shop. The regulator IC costs around $25.

SONY KV32XBR400 (year 2000) screen is blank when power turned on


The clicking you are hearing was probably always there, it's just that when something goes awry, one pays closer attention. What you hear is probably a relay that connects power to the rest of the set. Since our sets can respond to a remote, they always have a little bit of life to supply power to the infra-red receiver so it can respond when 'off.'
I see two possibilities; the relay itself has burned contacts and not always 'closing' as it should, or, the high voltage circuit is failing to turn on as it should causing an excessive current to flow for a moment and a protective circuit to trip and disconnect the power from the main supply.
It probably will get worse if the problem is not found and could damage other circuitry as well.
Good luck finding a TV repair man who isn't deceased or out of business but I do recommend you try to have it repaired. Once repaired, it will outlast most any panel/flat screen-type TV as it appears nearly all of them are failing much too early in life.
You can check by entering just "LCD," "plasma" or "projection" plus TV in the search window here.

Usually what I find in those sets with that symptom is that the solder joints have cracked on the convergence output IC. When this happens you may see the colors no longer lining up on the screen, and slapping the side might temporarily straighten it out again. After a while the convergence IC will short out inside, which overloads the convergence power supply, possibly shorting a diode and/or burning the resistors. The computer senses that the power supply is not working right and shuts the set back off. When I make a housecall for a set like that I charge $150, but some shops charge up to $400, so ask around.

Toshiba 36zp38b picture problems


With it only being about 3 years old, I would suspect bad solder connections rather than defective components like Capacitors. You may get the symptoms to come and go by slapping the side of the set or jaring it slightly which would prove the bad connection thesis. It is not a permanent cure however and you can make it worse if you keep doing that. A solder repair shouldn't run over $225 in my opinion.

36" CRT Toshiba has that vertical issue mentioned on here a bit


Your problem is most likely caused by a cold solder joint in the vertical circuit. Normally this is easy to find and correct. The problem will only get worse over time, but not likely for more damage to occur.
