SOURCE: Sony Flat Panel tv with no Picture

Flat panel TV's typically do not have "bulbs," but rather backlighting.  Plasma displays are especially touchy during movement.  I would suggest checking your warranty status, as it's probably not something you can easily repair.  If you wanted to take on the repair yourself, be careful not to lay down the screen, as it will drastically shorten the life of the Plasma display.  I would start with checking the system boards for possible damage, since you did hear a "click," It was probably a fuse, chip, etc.

SOURCE: will not turn on no power proscan tv model no 26la30q

Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. Or, something simple like a blown fuse inside the TV. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:

1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.

SOURCE: panasonic viera tv won't turn on. Power light

hello, you have a either your su, sd or sc boards fualty and it is a driver sos1 thats what the manual reads the best thing to do if your not electronically inclined or able to fix it is to get a service manual and make sure it is for your specific model and size you will find what the 7 blink codes mean, on my side i have a 42 in pana the service manual for this set and your is similar so since it is not the same model i cant tell you exactly what the truoble is but your best bet is to find a service manual find the 7 blink fualt then without getting ripped off you will know what the service man needs to do if you dont know or cant replace the parts yourself that is besides having to download firmware from your computer to a sd card and update your set but you need to solve the blinking code first it may solve the entire issue. the tv should come on when you resolve the blink codes or replace the fualty board or boards

Proscan inverter board won't power o, Any ideas?


hi travis,
you din't mention what happened after you disconnected the main board. unplug and plug is not bypassing.to bypass the main board you have to keep it disconnected.if the back lights come on and stay on after main board disconnected, the main board is defective.
good luck.

My proscan tv has the blue light but wont turn on


Most likely it's the power supply board that went out. (part of it still works is why you get the blue LED when you plug it in.)

If you decide to try to fix it yourself, BE CAREFUL! The power supply board has capacitors that can hold high voltages for many hours after the TV's been unplugged.The equivalent of sticking your finger in a light socket.

You'll need the part number off the power supply to get a replacement.

Proscan TV


with no picture and no audio i would more than likely suspect the main AV Board needs replacing.
Take the back of your tv and get the part number of the AV board ( THE ONE WITH THE INPUTS AND SCART SOCKETS) then Google or Ebay for a replacement.
95% thisd will cure your problem.
Hope this helps
