The inverter is the usual suspect with that symptom. It may be hard to find a replacement inverter for an apex model. But you might be able to get one from www.tvrepairworld.com

Your problem is in the power supply. In the power supply, you will find a burned tantalum capacitor. Location is C205, near an inverter connection. The value is 6KV at 47 joules. These types of capacitors are also used in surge suppressors. They are sometimes used in the ultimate voltage control similar to the bridge rectifier. In this case it is used as a standby, always on, waiting for you to power up your TV, and to light your screen to watch. A lot can be said here. Find a reputable electronics store (not a fan of Radio Shack for TV parts). Show them your power supply and the location and value of the capacitor you need. I found one in another power supply (Philips TV power supply). Replaced the cap in the Apex LD 4088. I am a TV Repair, and save almost everything. But your TV will come back to life. Thanks for asking, Matt of Martins TV Repair.

SOURCE: i cannot program my comcast control for an APEX

I just spoke with a rep at Apex about the comcast code for the LD4088 TV. I was told to call 1(800)284-8828 M-F for specific customer service for this TV and that if they cannot help us, the TV may be so new that we may have to wait for the next generation Comcast remote in order to control our TV with a comcast remote. Frustrating. Isn't it?

check to make sure that your tv is not starting in "line in" mode and to be starting in the tv mode.
if the screen flashes then goes out then you have a back light problem and it needs to be serviced! possible bad power inverter for the back lights

SOURCE: I have an apex ld4088 tv. And i have insight

When I bought this at Target on black Friday, I did not realize the remote was missing. I had a spare universal laying around. Went online for codes and found nothing but codes that didn't work. Bought a low-end one at Target (who refused to give me one after the TV's sold out, said all I could get was a refund but I got a GREAT price on it and didn't want to spend another 150 to replace it.) Low-end remote did not work, returned it and bought a 70 dollar remote and that didn't work either. Got fed up and called Apex, who jerked me around twice before finally telling me there is a special number if you buy it at Target. Called them and they said fax the receipt and serial number and they would mail me a new one. Did this TWICE and never got a remote, called and demanded a supervisor and explained the situation, he ask my name and info and within 5 minutes I had a conformation email with a tracking number. The aim sucks, but it's not the TV, it's the signal on the remote being weak. The supervisor told me there is only 1 universal remote2_bing.gif they know of that works with the TV since it is so new. His name is Marcus Chan and his email is acctemp@apexdigitalinc.com
Hope this helps!!!

I awoke this morning to find the sound on my Apex Digital LD4088 LCD tv is dead. The picture is fine, but sound is dead, how do I solve this?


Download the user manual to your TV. Clik here to download it. See whether audio options to it are set right. If all are right, check its speaker. If speaker is OK, the audio output circuit section should be troubleshooted.
If you feel any difficulty in downloading the manual, send your email address to me. I'll send a copy of it to you by return mail.

I have an apex 4088,have had it for 5 months.Suddenly I only have sound,no picture


Hello
If sound is OK and there is no picture, means the video processing section of your Apex TV is faulty. It may be either to the absens of voltage or a damaged processor IC inside the circuit board. Being a new set, it will have guarantee. If it is in guarantee period, get it service by the Authorised Service Center for Apex. The processor board costs some more. Do not open it, if guarantee prevails even now. Opening the set for any purpose will void the guarantee. OK.
