20 Most Recent Proscan 26LA30Q 26 in. LCD Television Questions & Answers

What is the TV source? For some sources (set top box), you may need to turn on the captions using the menus of the box.

Assuming you are using a source that gives captions that the TV can interpret, if you have the Proscan 26LA30Q remote, press the CC button to toggle through the caption options. Another route is to press Menu (either on the remote or the buttons on the side of the TV) then select the Feature submenu with the left/right arrows. Press Enter (menu when you use the buttons on the TV) then navigate to the Digital Closed Captions option. Here you can set the captions to on and adjust the size, style and color of the captions when they appear on-screen.

If you are using a universal remote, try the CC button. If it doesn't work, try another code for the Proscan TV on the remote. There are some codes that may not control all of the functions of the TV with the remote.

Crutchfield has the manual for the TV on the product site: http://www.crutchfield.com/S-Kaec3gBqVtM/p_68326LA30Q/Proscan-26LA30Q.html . The direct link is http://a248.e.akamai.net/pix.crutchfield.com/Manuals/683/68326LA30Q.PDF .

I hope this helps

If this TV came with an universal remote, try pressing the TV key. Sometimes it works.
If that did not work any other RCA, GE, Proscan universal should work.

If the problem is same with different input devices and you have ensured the are no loose contacts in power outlet, RC jack, cable and sockets, the TV needs servicing.

You have to start checkin from its main ON/OFF switch itself. If the switch have any contact contact trouble, the set will not turn On, even though you hear the click sound from the switch. If switch is Ok, then you have to come to the power supply regulator board. It can be easly recogonized the powe supply regulator boad. The main supply line will go straight to it. There will be more that 5 or mor secondary voltages from it, according to Tv model. These secondary wupplies will energzed only after the power supply switching circuit work properly.
Ther is a fuse [ a cartridge type; replaceable]. Check the fuse first. If it has blown; be carefull when you replace it; because there must be some reason for the blowing of that fuse. It is really a protection device. Before replacing it, you have to check the entire power supply board for some short circuit. If you have sound knoledge in repairing Switched Mode Power Supply [SMPS]; just proceed. Otherwise get it repaired by any experienced service technican or by authorised service center for Proscan. OK.

Hi Todd,
This kind of symptoms indicated of LCD controller board malfunction. First isolate the unit from loose connection inside because it will do same symptoms. Take it apart and pull-out the cable connectors from the LCD controller board, power supply board, and main board, inspect and then re-insert and ensure the connections.
If the symptoms still persist check the supply voltage in the LCD Controller board if present. If yes, this is an indication that the power supply is not the issue but the controller board. You must replaced this board to back the unit in normal operation.
If the supply voltage is not present in this board, your power supply output has a problem and disable the controller board. You must check this board from faulty parts like open fusible resistor(low resistance value), open/shorted regulator transistor/Zener diode, bad solder joints in line with the supply voltage (crack/dried/cold solder).
If you don't have necessary tools and test instrument and can't troubleshoot the unit yourself, I would advice you to look for a qualified technician to isolate the faulty parts.
Also check if your unit is under warranty/extended warranty period, avail it because the manufacturer will fix it for free. Don't attempt to open the back cover because it will void the warranty.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

If you were to log on to the manufacturer's web site, I think you will be pleasantly surprised as usually one is able to download, by model number, Customer Instruction Manuals, list of Dealers for spare part supplies as required.

Just Google the manufacturer's name and follow the links. Make certain you are directed to the manufacturer's web site as some search engines direct you to other sites and they charge for the information that is normally free of charge.

I hope this helps.
