The VE1020 didn't come with a mount. It came with round plastic spacers (16) that were 1/4", 1/2", and 3/4" thick. You could stack these on the mounting screws to get the clearance you needed for under the cabinet mounting. You will note that there are 4 through holes for the mounting screws, one in each corner of the chassis. Sheet rock screws of different lengths will work. You can easily just cut four small blocks of wood or use 3/4" - 1" wood dowel cut to the length you need. Drill a through hole in the dowel. Paint them to match if they will be exposed.
If the fuse is intact in all probability the power supply unit is OK. If your Horizontal Output Transistor fails you will hear a high pitch whistling sound . Any way its the black three legged device mounted on an aluminum heat sink near a transformer from which a Red wire goes to the top of the picture tube.
Sounds like a bad power board. They have random meltdowns all too often. Usually the cause is an overheated transformer caused by power transistor short outs. Possibly sell it. Could get over $100 for it if sold online.
A common failure in these units is Q401, Toshiba p/n# Bz510004 is a 2SA1624 (HV amplifier) which finally fails due to a resistor R408 Toshiba p/n# Bz210285 a .47 ohm/1w metal oxide having changed in value and at last opening...
This isn't an expensive repair for a qualified shop - but I would suggest not continuing to test your shutdown circuit. What's happening is that HV (high Voltage) is builds beyond tolerances and the shutdown circuit turns your unit off to keep from causing any severe damage. If it failed you could likely burn out the SMPS or cause some substantial damage..
Your unit may have been switched to Progressive Scan mode, which a normal analogue TV can't recognise. Check your VCR/DVD manual for instructions to change picture settings and set it back to PAL TV. Failing that try a new 3 conductor lead from unit to TV. Also unless you yourself were actually the one who accidentally unplugged the unit, it is just possible that whoever did has not (for whatever reason)disclosed to you the full detail of what actually happened to cause it to fail. If it was in fact dropped or fell, pulling on the AV leads they could have been rendered useless or the unit itself might have suffered a Gforce-shock causing component failure or circuit board fracture. All the best with this one
Look on the back of the unit. On the right hand side will be a removable panel. Inside the panel is a recessed area where the TV Tuner module is mounted. It plugs into a small D connector on the left side of that recessed area. If there is no tuner module mounted in the recessed area, you will not be allowed to select the TV options in any of the menus.
I owned the under the counter since jan 07 and the same problem. Called poloroid and they said the warranty is only for 3 months. Since I purchased it on ebay they said i have no warranty since i purchased it through a 3rd party. they said they would replace the tv for $60. plus s&h. WOW SOME COMPANIES JUST DON'T STAND BEHIND THEIR PRODUCTS. CRAP PRODUCT DON'T BUY IT.
