I don't have schematics of this particular tv but I would try to help you to diagnose and rectify this problem.
I think that your tv has problem of pin cushion, incorrect picture size at sides, this is cause of few defective parts in Pin Amp area.
I need few clear and focused pictures of both sides of TV main board to see what part is damaged.
Thank you.

    You can use Diode "PG156R" OR "EGP20G" as replacement part for D155.
    Both diodes are high frequency and used in Pin Amp stages in most TVs.

Advent tv displays green


If you are saying no red: The model indicated here Recoton Advent Advent Q1435A TV is a 14 inch set.

first it may be cheaper to replace than repair--That said if no red look to the small circuit board at end of picture tube (it plugs onto the tube).

It will have either individual output transistors or a single IC.

What (if only one color missing) I would look at is the bottom side which faces to the rear---a circle of solder connections--possible one is broken--there will be one for each red, green, and blue--not always easy to see but if any of the solder connections look cracked or even broken loose-----

I have an Advent Television Model Q2035A and would like to know if I am going to need a converter box for it? I have an old timey antenna that rises above my house' roof. The wiring on it is spliced for...


Yes you will most certainly need a converter box. At Radioshack you should still be able to get the piece that you would attach the spliced wiring to.One side of the piece I'm talking about has a screw for each one of the Y shaped spliced ends to attach to. Sometimes there are two places to attach things and sometimes there are four so buy the one that best fits your needs. Then the other side of the piece has the male part that will attach to the female antenna in part on the converter box. Then a cable goes from one of the outs on the converter box to one of the ins on the television.

Advent Tv on direct tv with snow showing on screen


This is the best solution for your problem as a 40 year experience with wires etc. Go to the source of your cable signal connector . Open it and clean the terminals with emery paper , sand the end of the cable shiny clean from corrosion , get a new barrel connectors with gold terminals if possible lengthen the ends of the cable , insert and tighten good, use thick rg-16 or rg 40 cable with good insulation ends crimped professionally with a crimpier or buy ready made , not from dollar store. Get a gold plated professional splitter if you need one or two , it will cost about 15 or more each . Make the cable runs as short as possible, using the thick good cables. If needed get a signal magnifier. From radio shack or the source etc. Connect them good and tight . Ground the splitters . Problem solved , you will get crystal clear channel 2 to 7 including 3 and 4 . Isolate the TV cable from other cables and power wires. Vitally

Curves on TV


You have a bad capacitor off the vertical output I.C..Find the pin off the I.C. that represents the out of the I.C. If you have a capacitor checker, you can check the ESR(equivalant series resistance) to see if it reads high.Look on the internet for a schematic,this will show which pin of the vertical I.C. is output,and the cap. that leads off it..

Advent HT2751A display no good until after 1-2 hour warmup - maybe


After 3 years, I finally decided to open up the TV and do some troubleshooting. Found out the problem, It was a blown capacitor Location C554 Capacitor value is 2200uF 16V - costs about a dollar to replace yourself and the TV works brand new.
