I have a Proscan model # PS36800HRJX1 and having a hard time putting it on DVD mode to be able to play a movie. I just bought a remote for it and can't figure out what's the problem. How do I go about it?

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: i have a 42" Proscan standby light comes on but the tv wont turn on

I see so many here with no sound/no picture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signs of damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down the problem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the generic ones like Radio Shack). Many fuses are special even aside from amperage--Don't put a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses a standby power supply that runs 7/24 and a main supply (some are combined and some not.

Here aside from checking fuses you want to examine all the filter caps on the power/standby to see if any are puffed up or buldged up in some fashion--I attach a photo of a good one---top should be silver metal and PERFECTLY flat and have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating (saves money) which causes them to fail in a year or two---the standby runs 7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buy and try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over. If set is opened at least look for puffed up and bad caps like in this photo

My proscan 42la45h model lcd the tv has power but wont turn on. Any suggestions


check fuses. if it turns on via remote control replace batteries. First remove from mains / power for a good ten minutes and see if this brings any benefit. There is not a lot to go wrong with fp tvs really.
If the issue is not one of these, and it does turn on via remote it might be that the control handset is faulty.
After this you can think about getting the set itself diagnosed/inspected

I have a 47" Proscan


Right now the standby 5vdc power supply for the processor on the main board is working (the standby power supply and the processor are running 24/7, even when the TV is OFF) but nothing else, and since you cannot even turn on the TV at the TV control panel it may mean that the main board is not functioning.
I would inspect the power supply module first though just to make sure it does not have any bad caps, burnt parts since bad DC can make the TV to have strange symptom.
Please read my guides first to understand more.

The power supply is bad. It supplies enough power to light the red LED when the tv is powered off, but not enough to power up the tv. You can find one on ebay.

Proscan 36 inch tv


Good day.

The spark the you see means that your wall socket is loose. Have it fixed by a qualified technician. With regards to your unit, it has an internal problem. In my experience, the power supply is not dissipating power to the circuitry. The problem is contained in the power supply, have it checked by a technician.

ProScan wont turn on


PS52690 52" projection TV (CTC188 series) that won't power up. From what I have read here and other places, the most common cause of this is the HV splitter. Actually, when the unit was 3 years old, the HV splitter went out and had to be replaced but it was under warranty at the time. I have found that the part I need is 205064 and runs around $40-$70
A post in another thread said that you could test to see if the HV splitter is really the problem by disconnecting the HV anode (big red wire) from the flyback (not the splitter since that will arc), plug the TV in, power it up, and if the power stays on and you hear sound, replace the HV splitter to fix the problem.
